Time frames are approximate, variations occur due to difference in the weather every year.

January and February is a good time for pruning most trees, making it easier to identify structural problems or dead wood.

When the ground thaws, usually by mid to late March, we can begin Rootcare fertilization of trees and shrubs with our slow release fertilizer.

April and May mark the beginning of the growing season, and is when we begin monitoring plant development and weather conditions in order to time our pesticide applications.

Evergreens are pruned in June or July after the new growth is completed, and is when symptoms of leaf diseases such as Oak Wilt begin to appear on infected trees.

August, September, and October are good times to apply systemic insecticides that will prevent infestations next year because the plants are building crowns and root systems as the top growth slows down.

In November and December we continue tree and shrub fertilization until the ground freezes. Our slow release Rootcare Fertilization formula will not promote unwanted late season growth.

Tree and Shrub Maintenance

Rainbow offers a complete line of effective, knowledge-based tree and shrub maintenance services. You will find expert service and consideration for your property.

Pruning - Appropriate tree and shrub pruning employs an understanding of plant structure, physiology, biology, and aesthetics.

Cabling and Bracing - Proper cabling and bracing techniques will lengthen the service life of trees with poor structure or weakened limbs.

Systemic Growth Management - Cambistat, a plant growth regulator, will maintain the size and shape of your trees. Cambistat can reduce tree growth by up to 60% over a 3-year period, increasing the time frame between needed pruning. This is an important maintenance issue for trees growing in confined spaces, near houses, decks and patios, sidewalks, power lines or for trees that block scenic views.

Tree and Shrub Removal - Our ISA Certified Arborists can safely remove even the most hazardous trees.

Plant Health Care

We apply the latest research and technologies in developing plant health protection strategies. Our tools include special soil and plant injectors, air spades, and chemistries designed for specific beneficial outcomes. Complete root care and fertilization techniques round out our comprehensive plant health care programs.

Tree and Shrub Fertilization: Our Rootcare Fertilization with the addition of beneficial soil organisms improves soil conditions, encourages proliferation of roots, and increases plant vigor.

Insect and Disease Management: Accurate disease and insect diagnosis, in combination with accurately targeted treatments, minimizes the impact on beneficial organisms while effectively controlling pests.

Dutch Elm Disease Prevention: Since 1976 Rainbow Treecare has protected more elms against Dutch elm disease than any other company in the United States. We do it by using proven application techniques and the only fungicide proven through university testing to consistently protect elms against beetle carried infections.

Oak Wilt Prevention and Therapy: Alamo fungicide injection protects red, white, and bur oaks at high risk of infection via root grafts with a diseased tree. Alamo has also proven effective when used therapeutically to save white and bur oaks that are moderately infected.

Construction Site Tree Preservation: Rainbow Treecare's experts can help you lay out a plan to preserve or minimize the damage done to the important trees on your property when building your new home or adding an addition on to your existing home.

Lawn Care

A healthy lawn is achieved through a comprehensive, site specific program. A thorough understanding of how lawn care practices impact all landscape plants determines which types of products and services are right for you. Our lawn care services are specifically designed to benefit your entire yard.

Custom Fertilization: Every yard environment is different so we analyze the specific needs of your grass in order to prescribe just the right amounts and types of fertilizer needed to enhance your lawn. We offer a choice of organic-based or man-made fertilizers.

Weed Control: Weed control chemicals must be used carefully in the yard environment. Used improperly, many broadleaf weed herbicides are damaging to the trees and shrubs. We carefully choose the herbicides used and selectively treat weeds to minimize the possibility of damage to your important landscape plants.

Seeding: We can overseed your lawn with the types of grass best suited to the growing conditions found on your site. Some times fixing a problem lawn is as simple as getting the right type of grass.

Aeration: Regular aeration is an important part of maintaining a healthy lawn. Aeration alleviates compaction and helps to keep thatch under control.

Disease and Insect Management: Rainbow Treecare has the expertise to deal with a variety of pest problems commonly found in lawns.
