Tree & Shrub Care from ULTRALawn

Flowering Crab Trees

Mature trees and shrubs represent a significant investment in your landscaping and add to the value of your property. With proper care, your plantings will look terrific and stay healthy, making trees and shrubs more resistant to disease and insects throughout the growing season and hardier during our infamous Iowa winters.

It's good to remember that some insects are beneficial to the environment, but our insect and disease sprays keep populations at a controllable level and help stop any disease before it gets out of hand.

ULTRALawn's tree and shrub program provides landscape plantings with the required nutrients to safeguard their health and protect them from insects and disease. We use special equipment that provides deep root fertilization to the feeder root zone. That makes it easy for trees and shrubs to take in the nutrients and realize the full benefits.

Proper nutrition is particularly important to young plants. Their potential for fast growth is the greatest and our program can achieve as much as three years of normal growth in just one year. Our combined use of contact (sprayed) and systemic (root-fed) products also reduces the risk of excessive insect activity and disease. Unchecked, these can weaken your plantings and, in some cases, be fatal.

Standard Program:

  • Early Spring - Dormant oil spray (targeting scale and over-wintering insects) and deep root feeding (Please note that these are two separate treatments)
  • Late Spring - Insect & disease spray (typically in May), targets insects and helps prevent/control disease
  • Early Summer - Insect & disease spray, second application
  • Summer - Summer insect spray targeting problem insects
  • Fall - Deep root feeding to provide long term nutrients

Emerald Ash Borer Treatment

Sadly, these little buggers are finally here. Fortunately, it's now possible to treat ash trees to reduce the chances of losing them to emerald ash borers. The key is treating them before they have become infested or in the very earliest stages of infestation. You also need to know that treating affected trees will become an annual event once the insects have reached your locale. ULTRALawn can treat ash trees in the early spring once the ground has thoroughly thawed. We treat by drilling small holes in the trunk for systemic treatment.
