Our custom blend tree and shrub fertilizer provides a source of essential nutrients that plants need to grow normally and be healthy. Nutrients are also supplied by the soil and decomposing organic matter, but adequate quantities of certain nutrients may be lacking. Young shrubs and trees will especially benefit from fertilization. Our fertilizer blend will stimulate growth and improve the color and appearance of plants.

Tree/Shrub Fungicide

Fungus is a common ailment for trees and shrubs. When fungal spores come in contact with a susceptible host they begin to grow, enter, and feed on the tree or shrub. Spores spread through the air on windy days, hard rains that splash the spores up onto trunks and leaves, garden tools and human movement. Fungicide applications help to stop or inhibit the growth of fungi on plants and can help you keep your ornamental trees and shrubs from succumbing to fungal diseases.


Countless insects live on, in, and around trees - many are harmless, while others can cause fatal damage. We offer a variety of methods and modes of action to deliver insecticides to trees and shrubs based on the specific target.

Iron Treatments

Iron plays a major role in producing chlorophyll, the green pigment in leaves. A deficiency of iron reduces the amount of chlorophyll the leaves produce. When chlorophyll is reduced, a yellowing of leaves occurs. This is an early sign of iron chlorosis. On deciduous trees, iron chlorosis causes the leaf veins to remain green while the area between the veins is yellow-green to yellow. In advanced stages, twig dieback may be observed, especially toward the top of the tree and ends of the branches. We have several methods to correct iron deficiency depending on the condition and size of tree

Dormant Oil

Dormant oil is used on trees and shrubs to suffocate insects and their eggs nesting in branches. Using dormant oil on will not eliminate the problem with these pests, but it is the best way to cut off most of the population. Once the oil solution is sprayed on all the branches of a tree or shrub, it penetrates the surface of the insect’s hard outer shell and suffocates it by not allowing any oxygen to get through. This application is recommended early Spring and late Fall.


Dealing with environmental stress is a constant battle. Preventing damage brought on by freezing winter temperatures, exposure to salt and summer heat can now be addressed easily. This application forms a thin, flexible, water-repellent layer on plant surfaces. Our application will protect your plants against drought, extreme temperatures, wind and sunscald. Most applications are made late Fall prior to Winter.

Japanese Beetle (Preventative and Curative options)

This application consists of a broad-spectrum insecticide for prevention, maintenance, or control of an active infestation and treats over 75 pests including the Japanese Beetle. This product provides a barrier for crawling insects, protects ornamental plants, trees and shrubs from hazardous pests (Japanese beetle) and helps control nuisance flying insects. This product leaves a lasting residual and is odorless, non-staining, dries clear and is safe around children and pets.

EAB Treatments (Emerald Ash Bore)

While the adult beetle causes little harm, only nibbling on foliage, the larvae cause considerable damage because they feed on the inner bark. While the process can take several years, EAB has killed millions of ash trees across the country by disrupting their ability to carry water and essential nutrients. EAB has been positively identified in residential trees in several Iowa counties (including our service area) over the last several years. Treatment for EAB is a systematic insecticide to control the pest population. Our process involves a trunk injection with TREE-äge (active ingredient: Emamectin Benzoate). The preventive treatment is effective for up to two full growing seasons and is typically performed from April through October.

Evergreen (Rhizosphaera) Needle Cast Fungicide Treatment (Available in a 4-step program)

Rhizosphaera needle cast is a foliar disease of evergreens. Rhizosphaera needle cast causes needles to turn purplish brown and fall from the tree, usually from the inside of the tree working out and from the bottom of the tree working up. For effective control, infected trees should be treated once in May and again four to six weeks later, up to four applications. Fungicides do not cure needles already infected, but they protect the newest growth as it emerges.
