General Fertilizing Tips

>All conventional fertilizers contain some combined or individual amount of nitrogen (N), phosphorus (P) and potassium (K). Plants use all three of these components in different ways. Nitrogen promotes quickened stem, branch, and leaf production and also provides plants an illustrious green color. Phosphorus stimulates productive root growth and hardiness to extreme conditions, making it ideal for transplant fertilizers, and potassium stimulates the overall immune system of the plant. In addition to these three main elements, iron is often added to fertilizers so that other nutrients can be made more available to the plant. Micro-nutrients, such as iron, are sometimes required by certain plants prone to specific deficiencies.


>When fertilizing plants, be sure to stay mindful of the general feeding area encompassed by the plant’s root system. With trees, this means feeding an area roughly one and a half times the size of the canopy beneath the tree.

>When feeding make sure to broadcast fertilizer into holes roughly 6 to 12 inches deep.

>Be sure to apply fertilizer early enough for active growing to cease in time for winter dormancy.

>After the first year, fertilize trees and shrubs regularly. One quarter pound of commercial nitrate fertilizer per year of growth for the first 5 years, broadcast under the spread of branches in Spring is excellent. Small fruits and shrubs respond to the same treatment.

>Roses benefit from regular application of fertilizer through the spring and summer. Methods of foliar and liquid feeding are quickly effective.

How to Fertilize Dogwoods

Dogwoods in natural areas do not require fertilization. However, trees in yards and restricted growing sites can benefit from a suitable fertilizer. Soil testing is recommended to determine fertility levels and application rates. Broadcast fertilizer on top of soil. Fertilize trees in late spring or early summer after leaves complete expansion. Never use fertilizers containing weed killer. Always thoroughly water the area after fertilization.
