Battling Wild Violets in Iowa Lawns

wild violets in iowa lawns

In an earlier blog post, we talked about creeping charlie as a problematic weed in lawns. Wild violets are another broadleaf weed that causes some frustration due to their persistence and difficulty to control. Wild violets thrive in and are first noticed in shady, moist conditions, but can withstand drought once they’re established.  A thin stand of turf will also be more susceptible to wild violets and other weeds. Wild violets and creeping charlie are frequently mentioned together, but the reasons behind their persistence are a bit different.  Let’s take a closer look!

Identification of Wild Violets in Your Lawn

Wild violets have a heart-shaped leaf that grows on a single stalk. At times throughout the growing season, they’ll sprout small flowers that are blue/violets that also grow on individual stalks. At times, those flowers can be white too. Violets don’t grow very tall, so they usually aren’t seen from a distance like grassy weeds that grow faster than turf.

As mentioned earlier, wild violets thrive in shady, moist conditions. These conditions aren’t favorable for turf growth, which then exacerbates the issue. Tree limbs can be raised or thinned out to create more sunlight. If that isn’t a desirable option, that area could be converted to a low-maintenance landscape bed with shade-loving plants like hosta, astilbe and coral bells. As much as we love turfgrass, we also acknowledge that some environments aren’t meant for grass and would be better served in a different capacity. Aesthetically, a landscape bed may be more pleasing to the eye than a struggling patch of turf.

So, why are wild violets so difficult to control? There are a few different characteristics that make them a worthy adversary:

  • The leaves of wild violets have a waxy coating that makes it difficult for herbicides to fully penetrate the leaf. We’ll touch on that when discussing controls for wild violets.
  • Wild violets are resistant to a variety of herbicides. Our program includes herbicides that are effective, used in a rotation.
  • Wild violets have a very thick root system and spread by thick underground roots called rhizomes. Repeat applications are necessary for the products to work their way into these roots.

Controlling Wild Violets on Your Property

There are two general methods to controlling weeds and pests; cultural and chemical. Cultural controls are non-chemical methods that are aimed at changing the environment or suppressing growth with practices designed to strengthen the turf. These include:

  • Mowing your lawn at the proper height, and at appropriate intervals. Lawns should be mowed at least 3” through the growing season, and raised to 3.5” in periods of extreme drought or heat. Lawns should be mowed frequently enough that we’re removing NO MORE than 1/3 of the plant. At times, that may mean mowing every 4-5 days. Proper mowing is the #1 practice that has the largest impact on turf quality.
  • Fertilizing at regular intervals and proper amounts to make the turf as thick as possible. Weeds are great at finding open spaces to grow, and a well-fertilized turf has a thick, full canopy that will prevent weed germination.
  • Proper irrigation will help keep our turfgrass healthy, while also preventing a habitat that encourages wild violets. Violets love moist soil, and watering frequently will not allow the soil to dry out properly. A good irrigation schedule waters the lawn when needed, and provides about ½” of water at a time.
  • Aerating at least once per year (spring or fall) is a necessary practice to help the soil and turf. Aeration relieves soil compaction, removes extra thatch, and improves air, water and nutrient movement within the soil. Regular aeration in conjunction with the above practices will yield a thick, healthy turf that will do a great job keep out any weed.

Chemical control, using herbicides, is usually necessary when dealing with wild violets. Because of its growth habit and characteristics, one treatment is not enough to eradicate wild violets. Repeat applications will be necessary, along with the proper lawn care practices outlined earlier. Certain products stay in the plant for longer periods of time and are metabolized by the plant more slowly than other herbicides.

Here at UltraLawn, we utilize these products whenever conditions are right for their use. Full program customers also receive free service calls; visits where we can come address issues and spot-treat problematic weeds between regular visits. UltraLawn is focused on proper weed control, and thorough coverage and treatment of weeds is part of the program. We utilize the best products available, and regularly change the tools in our arsenal to make sure we provide the best service possible.

Killing Crabgrass Weeds in Cedar Rapids & Iowa City Lawns

crabgrass weeds cedar rapids iowa city

Summers in Iowa can be hard on our lawns. The days are long, so sunlight is drying out our landscapes for over 12 hours a day. The weather is hot and humid, weakening the turf and making it susceptible to various insects and diseases. Summer also brings about annual grasses, and the one that gets the most attention in this part of the country is crabgrass. Crabgrass is considered a “warm-season grass”, meaning that it won’t germinate until late spring, and thrives in the hottest weather. Unfortunately, this time of year is hardest on the grasses we want to keep strong (these are considered “cool-season grasses”), so crabgrass is able to compete and take advantage of these conditions. We’ll take a look at how to identify crabgrass, and what can be done to control it.

Identifying Crabgrass in Your Yard

Crabgrass generally has a lighter green color, but it does tend to darken as it matures. Crabgrass has a broad leaf that has a soft texture, and it grows low to the ground. It starts as single leaf, then over time develops tillers, which are new stems that arise from the parent plant. As more tillers develop, the plant flattens out and gets a more rounded appearance. As it matures even more, above-ground stems called stolons are produced. These stolons grow along the soil surface and will take root, forming an entirely new plant. Below are some pictures showing a crabgrass plant as it matures.

Because of its growth habit, crabgrass can withstand regular mowing and grows outward more than upward. Crabgrass is unaffected by drought, and will thrive and spread while the lawns may be suffering. After reaching maturity, seedheads are produced and that seed is dropped onto the soil or spready via mowers, wind, birds, etc. If conditions are right, that seed will germinate the following spring/summer. With crabgrass being a “warm-season” grass, it doesn’t like any semblance of colder temperatures. The first frost of the year sends crabgrass into dormancy. It will turn purple, then brown, and eventually “melt” away. While it is great to see crabgrass die off, it’s an empty victory if it was able to produce seeds. With each plant producing hundreds, if not thousands, of seeds it’s easy to see how things can get out of control.

Fighting (and Killing) Your Lawn's Crabgrass

Whenever we encounter weeds, we have two treatment options: post-emergent and pre-emergent. Early-season lawn applications should ALWAYS include pre-emergent for crabgrass. The cost for fertilizer to include pre-emergent herbicide is minimal, and if it’s 90% effective, it’s money well spent. UltraLawn’s full program includes crabgrass pre-emergent on our first two visits of the season. In order to achieve season-long control, this method is recommended. Over the years, its been found that sequential applications are needed in order to get the product into the soil early enough to knock back our first “wave” of weeds, and again to make sure control extends late enough into the summer. When these pre-emergent herbicides are in the soil, it creates a toxic environment for weeds that are trying to germinate.

Crabgrass pre-emergent will be effective right away in its first season, but it usually takes a few years of a consistent program to reach a point where a Cedar Rapids or Iowa City homeowner can boast of a lawn that is 100% crabgrass free.

There can be breakthrough in certain spots even if pre-emergent has been used for years. When we see crabgrass, it is usually along the edges of sidewalks and curbs. Those areas get very hot due to the proximity to pavement, and are also exposed to sand and salt from winter snow removal. That heat makes the product break down a little bit faster and leads to a bit of breakthrough.

Post-emergent control of crabgrass can be achieved with several products. Our mid-summer application is a granular fertilizer with optional grub control, followed by a thorough walk through the lawn to spot-treat weeds, crabgrass included. On lawns that have received pre-emergent weed control, very little time is spent treating crabgrass. If a lawn has NOT received pre-emergent weed control, much more time and effort will be spent trying to catch up. In some cases, an infestation is so bad that spraying everything would leave much more bare ground than is tolerable. It may be better to let the crabgrass go dormant naturally in the fall, which will allow the turf to fill in where it can. It will be imperative then to make sure pre-emergent is applied the very next spring.

As always, maintaining a healthy stand of turf through proper fertilization and mowing will go a long ways in preventing crabgrass infestation. We often see weeds when a lawn is mowed too short. Low mowing heights put undue stress on the plant, causing it to thin out. This creates room for weeds to germinate. What also happens is that low mowing heights eliminate too much leaf tissue. That leaf tissue acts as an umbrella, preventing sunlight from hitting the soil. With that umbrella gone, weed seeds are more likely to germinate.

2020 Derecho Effects on Cedar Rapids Lawns & Trees

uprooted tree grass from 2020 derecho in cedar rapids

There is no way to overstate the profound effect of the August 2020 derecho on the greater Cedar Rapids area. It will always be mentioned in the same breath as the 2008 flood in terms of the power displayed by Mother Nature, and the raw destruction of its force.

It’s been estimated that Cedar Rapids has lost more than 80% of its tree cover since August 10, 2020. That number continues to grow as trees that were damaged, but not destroyed, by the storm eventually succumb to irreversible harm. Great efforts have been made to replant lost trees, but it will take decades for the city to resemble what it once was. The environment around us has changed considerably, and we’ll talk about the different issues and opportunities that have arisen.

Effects of Sun & Shade on Lawn Grass

For decades, lawns and landscapes around Cedar Rapids sat under an umbrella of shade. This influenced so many decisions that homeowners encounter when planning their outdoor space. The types of landscape plants that do well in shady conditions are certainly not the same as those that do well in full sun. The same thought applies to turf grass! We can’t pick grass types based simply on what we want or what looks better. The selection must be made for the specific environment. Older, shaded lawns in our area will have a high percentage of “fine-leaf” fescues. Some very old seed blends that were marketed for shady growing sites also contained “rough bluegrass”. When we communicate with customers about that type of grass, we will refer to it as poa trivialis, its scientific name. All the mentioned grasses are tolerant to shade, have a very fine leaf texture, and are adapted to cooler temperatures. Even under the cover of shade, hot and humid weather in the middle of summer will cause poa trivialis and fine fescues to show signs of stress. Their leaves will become brown, vigor is lost, and the overall appearance is mistaken for disease. This stress is usually temporary, and by fall everything looks green and healthy again. With no shade cover, these grass types are now in a losing battle. Many homeowners in Cedar Rapids are seeing this, and the ultimate solution most of the time is to re-seed or sod the lawn with grasses that do well in full sun environments. Replacing the shade would be great, but it will take decades to accomplish that.

New Weeds Arriving Post-Derecho

In August, many plants have sprouted seed heads, including weeds. Seeds are designed to travel, and they are most often moved by the wind. A multiple-hour weather event with straight-line winds exceeding 70 MPH, traveling across hundreds of miles, is certain to move a lot of seeds! We saw the results of this migration in the spring of 2021. Our customers and technicians were shocked by the amount of weeds found in lawns, but we were all baffled by what we were seeing too. Field pennycress, marestail, prickly lettuce, garlic mustard….plants that were typically problematic in farm fields and forest floors, were now growing in our lawns. I’ve pictured them below:

            

prickly lettuce weed

Prickly Lettuce

Garlic Mustard (In year 1)

Garlic mustard is an invasive plant that has been taking over forest floors for several years. It doesn’t do well in full sun environments, so in that regard it has declined in the wooded areas of Cedar Rapids. Where it concerned us was that the sheer abundance of seeds was causing it to pop up in landscaping beds and in thin areas on shaded lawns.

As the season went on, we found that periodic applications of broadleaf weed control and regular mowing were effective in getting rid of these weeds. We did see them emerge again in 2022, and prickly lettuce, in particular, has become one of the weeds seen most often by our technicians. Again, we are encouraged by the control that has been achieved with our broadleaf weed control.

Planting New Grass & Trees

After losing so many trees, the natural reaction has been a city-wide effort to replace them! Thousands and thousands of new trees have been planted in the last 2 years, with many more to come. When planting a new tree, nurseries stress the importance of watering. Without a doubt, consistent watering is imperative. Fertilizing the root zone is extremely beneficial, and growth rates can be increased up to 20% by giving the plant supplemental nutrition. Iowa soil is known for being fertile and offering a great medium for plant growth. When trees are transplanted, it can take time for roots to transition to their new home and thrive. Deep root fertilization helps hasten that process. Root growth and top growth (leaves and branches) maintain a balance. When the root growth is boosted, the plant absorbs more nutrients and water which are turned into leaves and branches. The extra foliage produces more carbohydrates which are sent to the roots to enhance root growth. It creates an efficient, productive “machine” that builds on itself and the end result is a healthier plant that will reach maturity sooner.

Plant selection and placement is important when trying to replace trees that have been lost. There is usually a desire to put the same kind of tree in, but several factors should be considered before planting something new. Many of the older neighborhoods in Cedar Rapids were filled with large, stately oaks that were likely there before. Most of the oaks native to Iowa are in the white oak family, which are slow growers. If the goal is to re-establish some shade, a faster growing species should be considered.

Transitioning from Trees to Grass

When trees came down, they left behind stumps that required grinding out and cleaning up. It’s not recommended to plant new trees in the same spot as an older tree that was taken out, so the holes left behind needed to be converted to new grass cover. The first challenge was making sure the stump was thoroughly ground down and as much wood material removed as possible. While a stump is being ground out, it’s difficult to see exactly where the large surface roots of a tree are since they become covered in debris. Those surface roots, if not thoroughly removed, will continue to be a nuisance until they are completely removed. With the tree (its anchor) now gone, they are more likely to come up out of the soil during our usual freeze/thaw cycles in the spring. Those exposed roots are not only an annoying eyesore, but they can be a tripping hazard and potentially damage mower blades.

With a large hole left behind, the steps to establishing turf seemed very straightforward! Add some soil, level and grade, then seed or sod the area. However, it was more of a challenge than we anticipated. One factor was the difficulty in clearing all wood material from the old stumps. It seemed that no matter how many wood chips and shavings were removed, more always seemed to bubble up to the surface. Grass can’t sustain growth in a soil that has a large percentage of wood material. Those wood chips have not broken down into organic matter yet that can sustain plant growth, and as they decay, air pockets are created. Those air pockets lead to instability of the soil, and until that soil has fully settled, roots cannot thrive in that environment.

Another reason it has been so difficult to establish turf where large trees once stood, is methane. When large amounts of organic matter decompose, methane gas is released. An overabundance of that gas is toxic to young roots that haven’t fully established. Therefore, we still see areas that are struggling to grow grass more than two years later. Unfortunately, this wasn’t learned about or realized until the spring and summer of 2021, when it was clear that something wasn’t working. Over time, we can expect things to keep decaying and turning into nutrient-rich organic matter. The amounts of gas given off should subside, and the growing medium will support turf growth. How long that will take is anyone’s best guess.

When is the Best Time to Aerate Your Lawn?

If you aren’t familiar with what aeration is or why it is helpful for your lawn, you are not alone. It’s something that can easily go unattended because it happens under the the surface. In fact, only 25% of homeowners in the United States aerate their lawn.

What is Aeration and Why is it Important?

Aeration is a process by which air is allowed to circulate through a substance. You can aerate a wide variety of things, such as milk, blood and also soil. It allows air to circulate through the lawn, but also provides a pathway for water and nutrients to reach the roots in a more direct manner. Aeration is usually accomplished by poking holes in the soil or by taking plugs of soil out of the ground. Core aeration requires heavy machinery that has been designed specifically for this purpose. The use of aerators creates exposed roots and surfaces of the plant are cut open, this can result in the plant dying out a bit before it heals. This process can take up to a couple weeks. 

There are natural soil aerators, like bugs and other soil-loving creatures that dig in the dirt – but they are not as effective or as capable as humans are, especially professional lawn care technicians. Following the service, you will notice a stronger turf beneath your feet after a few weeks.

When is the Best Season to Aerate in Cedar Rapids & Iowa City?

Before you go and buy yourself a lawn aerator or hire someone to come out, you should know that there are better times to aerate your lawn than others. While the long-term effects of aeration are beneficial for your lawn, it is also stressful to the plants if not done a the right time. We want to target the times of the year when the lawn is healthy and growing. In Iowa (specifically Cedar Rapids & Iowa City), we have cool season grasses. So spring and fall are the best times to both aerate and seed your lawn.

Now that its narrowed down to the season, the other huge factor is the weather. We know how unpredictable Iowa weather can be and it has an impact on when your lawn entering its “growing” stage. Because we tailor our lawn care program to take advantage of the weather conditions, we have found that these ideal times present themselves in the spring and late summer/fall for Cedar Rapids & Iowa City.

Ideal Weather Conditions for Aeration

In the spring, it’s best to wait until the grass is starting to or is consistently growing. For this to happen, the soil needs to be approaching 50+ degrees. There are a couple indicators we can use tell when a lawn is fit for aeration:

  • Green Grass – Every fall/winter, the plant goes dormant. As a result, it tends to turn a yellowish/brown color. In the spring, the new growth pushes out the dormant material, which is eventually mowed off and decomposes. When a lawn has consistently green grass, we know it has grown out of dormancy and it healthy enough for aeration.
  • Mowing frequency –  Mowing should be done often enough that you remove no more than 1/3 of the leaf blade. When the lawn needs mowed more than once a week, it is a strong indicator it would recover quickly from aeration. Mowing frequently is also a great way to break up the cores that have been pulled during aeration, allowing the soil to fall back into the holes and decompose naturally. 

In the early fall (August through October), growth of the plant isn’t as rapid as it was in the spring. However, this is when the root growth is accelerated as the plant is recovering from the heat of the summer months. There is always a chance your lawn goes dormant in the summer months, so you may need to wait until the grass greens again before aerating. Also if there was a summer drought, the soil may be too hard to even penetrate well. So waiting for cooler temperatures, shorter daylight hours, and increased rainfall make the fall a perfect time of year for the lawn.

Brown & Yellow Streaks in Your Lawn May be Ascochyta Leaf Blight

Ascochyta leaf blight on iowa lawns

Do you see bleached tracks on your lawn that typically follow the path of your mower? It could be Ascochyta Leaf Blight, which is a grass fungus that is found primarily on Kentucky Bluegrass, the most common grass in Iowa. This disease causes irregular patches of straw-brown color and will make your grass appear dead. This can pop up overnight, having a great looking lawn one day and a streaky yellow lawn the next. Weather can have a factor in it as well, as it is typically preceded by wet weather that turns hot and dry. You will start seeing these damaged lawns near the beginning of June, but they can also occur anytime throughout the summer.

This is a foliar disease that kills the leaf tissue, not the root system. This also means that the disease is transferred by infectious spores that sit on the surface of the grass. The “dead” patches are commonly seen where your mower tires track because your tires will easily spread the spores as you mow your lawn. Given that the outbreaks are so random, you typically won’t notice your lawn is affected until after the patches are already there. Once they appear, there is little you can do to make them go away. The good news is that recovery should only take 3-4 weeks, depending on how the growing conditions are over that time. There also are some practices you can perform regularly to relieve stress on your lawn and lessen your chances of a yellow, patchy lawn appearing overnight.

The four main cultural practices you can do properly for a stress-free lawn are: fertilizing, mowing, watering, and core-aerating. If you haven’t already, please consider our Weed and Feed fertilizing program. We apply the best products available in the correct amount at the right time. Mowing frequency, height of cutting, and blade sharpness are very important. Please be sure 2.5” – 3” of height remains after you’ve cut the lawn. Anything shorter than this causes stress on the lawn and allows weed infiltration. Never cut more than one third of the grass blade when mowing. And avoid mowing in the heat of the day, especially if the lawn appears to be wilting or starting to dry out. 

A healthy lawn needs 1” – 1.5” of moisture a week. It is best to water over night. Keep in mind, recovery will be slow and over-watering will not speed it up and may cause more problems. Keep up with fertility to promote re-growth. Core-aeration should be an annual practice especially for lawns that frequently have disease issues. Aeration reduces thatch levels and increases air movement, which allows the grass plants to dry more efficiently.

With this particular disease, curative fungicide treatments are not recommended. There are preventative fungicides available, but they must be applied before the problem appears. If we find a recurring problem, we may suggest preventative treatment(s) or over-seeding problem areas with varieties of grass resistant to the disease. We offer fertilization programs, aeration, and mowing services. Please contact our office if we can be of further assistance.

When is it Time to Hire a Lawn Care Professional?

hire a lawn care professional

Since establishing our business in 1985 and helping thousands of customers across the corridor, we’ve encountered a variety of reasons why people have trusted us with their lawn care. No matter the reasons, everyone has their own motivation, or breaking point, for letting professionals help. We’ll talk about the most common discussions we encounter when chatting with new customers.

“I Just Don’t Have Time to Worry About It!”

In a 2007 survey, 30% of American homeowners hired an outside firm to help care for their lawn and landscape. In 2017, that number had grown to 40% percent. More recent surveys would likely reflect an even larger percentage hiring lawn care companies. There are many factors leading to this; working more hours and more time spent commuting to and from work leaves less time during the week to work on the lawn and landscape. After a long day of work, it’s understandable that trying to get everything mowed before sunset is less of a priority. With less time during the week, that leaves the weekend for tackling the list of tasks. Sounds great! Well, maybe NOT so great. It’s going to be rainy all weekend? The kids have baseball and soccer games two hours away? We all work very hard to do things that we enjoy, and the purpose of a weekend is for relaxing and doing fun things. You can see where I’m going with this; our time is valuable, and taking care of a home (inside and outside) is time consuming. Our job is lawn care. We do during business hours what our customers cannot. If Mother Nature interferes with our day, we can adjust and complete things as soon as weather allows. Many homeowners don’t have that flexibility. There’s a limited time to do things, and bad luck can ruin the best of intentions.

“Am I Even Doing This Right?”

Turf management requires a great deal of technical knowledge and experience, like other skilled trades and professions. Many people don’t feel comfortable taking care of their lawn or don’t trust their own level of knowledge. A lot can go wrong if products are used incorrectly. Having been in business since 1985, the staff at UltraLawn has amassed an impressive resume of education and experience. This experience and knowledge has been used to come up with the best blend of fertilizers and weed control. We also have developed programs for controlling insects and disease on landscape plants and ornamental trees, mosquito control, preventing various insects from entering the home, and controlling vegetation in areas that aren’t mowed.

The products that we use are not the same as what can be bought at the “big box stores”. Raw materials used to create fertilizers vary greatly. Naturally, a better raw material demands a higher cost, and those products are usually used by professionals. Because of recent issues with manufacturing and suppliers, it’s becoming more difficult for homeowners and smaller lawn care companies to obtain high-level products. As one of the largest lawn care providers serving the Cedar Rapids and Iowa City area, we have developed relationships with vendors that have put us in a favorable position to make sure that we have the right ingredients to help your lawn.

One obstacle that may make a person hesitant is the cost; the equipment and products needed for DIY lawn care are fairly expensive. Unfortunately, those costs don’t appear to be coming down any time soon. By hiring UltraLawn to feed your lawn what it needs and to eliminate weeds, there’s no need to keep bulky equipment in the garage that may only be used for a few hours every year. You won’t have the hassle of keeping pesticides or fertilizers, let us worry about keeping that product safe and sound. Products and labor aren’t the only thing you’re buying when you are an UltraLawn customer. You’re buying over 250 years of experience taking care of turf in Iowa. That type of expertise isn’t easily found under one roof.

The turf industry is constantly changing, with new and improved products being released regularly. We are always looking for any way to improve results, and utilizing better science is an easy choice to make. As stewards of the land, we take very seriously our responsibility to care for the environment in a way that provides results for our customers and is kind to the ecosystem.

“The Work Has Become Too Difficult”

Lawn care is hard work. Mowing, mulching, raking, watering, pruning…not to mention an extremely rare hurricane-force weather event that turned everyone’s lives upside-down! As time marches on, we all slow down just a bit, and there is no shame in enlisting the help of others. “Many hands make light work”. We understand that some of our customers have taken meticulous care of their home for decades. The least we can do is approach their property with respect, care, and a keen eye for detail that leaves them satisfied and proud. We’re well-equipped and trained to do the job right!

No matter what reason someone has for calling in the lawn care calvary, the dedicated staff at UltraLawn is here to provide help in any way possible. And if you’re not completely sure about it, our estimates are free!

Tips for Seeding Lawns in Eastern Iowa

Seeding grass growing with UltraLawn

If you’ve been waiting to seed those thin or bare patches in your lawn, we suggest timing it between August and September to get optimal results for homeowners in Cedar Rapids and Iowa City. Once the seed is down, it’s important to begin daily watering immediately. At least twice per day is a must in order to keep the surface soil moist. Depending on the heat, additional shots of water may be needed. If the seed has been properly irrigated, you should see germination (sprouting) within a couple weeks. Once the germination process has completed (around four weeks) you can begin to reduce your watering routine to two to three times per week – an application of 1.5” of water at a time is typically sufficient. Seeded areas will need to be watered and fertilized throughout the growing season to allow it to thicken. These first year seedlings will not take drought well and will require your attention to survive the remaining hot summer months.

Once seedlings reach around 3.5” tall, you can include those areas as you mow the lawn. Make sure to leave 2.5” to 3” of the blade remaining – mowing too short will stress this new grass which can allow weed infiltration. Remember, these areas of your lawn can’t receive weed control treatments at this time and you should expect some weeds to show up as the new grass matures.

Avoid heavy foot traffic on these new patches until they’ve been mowed four to fives times. It may take up to a couple full years until these seeded areas reach the full thickness and health of your existing lawn. The speed of recovery ultimately comes down to water access so keep this rhyme in mind – keep it wet to avoid regret!
