Container Stock and Ornamentals

Many of the most serious container stock, greenhouse, and ornamental pests tend to be small insects including spider mites, aphids, whiteflies, and thrips. Timely applications are key in controlling these pests before they cause significant damage.

Foliar fertilization, a water soluble fertilizer that is sprayed on foliage, may help small woody plants, especially plants that are not getting enough iron. Foliar feeding of trees is becoming more popular and is often used to correct any micronutrient deficiencies. Iron chlorosis is one of the most common micronutrient deficiencies, due to typically high soil pH values. Iron can be added anytime during the growing season, as it does not stimulate excessive growth but corrects a chlorotic condition (leaf yellowing symptom).

Mist Sprayers are perfect for fungicide and foliar fertilization.
Nursery and Greenhouse users are spraying trees, shrubs, and container stock with application rates of 1/2 gallon to 40 gallons per acre without booms!

How do plants absorb nutrients? + -

A Michigan State College study has shown plants absorb nutrients not only through the roots, but also through the foliage, the fruit, the twigs, the trunk, and even the flowers. Plants can absorb nutrients 8-10 times more efficiently through their leaf surfaces than through their roots.

How should nutrients be applied to leaves? + -

When applying nutrients to the leaf, the nutrients move through the stomata downward through the plan–at the rate of about a foot an hour. When applying nutrients to the leaves in soluble forms, as much as 95% of what is applied may be used by the plant. If a similar amount is applied to the soil about 10% of it is available. Foliar feeding is effective even on dormant plants and trees.
