WHAT DO THOSE NUMBERS ON THE FERTILIZERS MEAN?

It is important to understand what the three numbers on fertilizer mean. They represent the ratio of Nitrogen-Phosphorus- Potash in the fertilizer. Each of these major elements has an important part in plant growth.

Nitrogen is vital in vegetative growth such as leaves. If your plants look chlorite (pale yellow) that indicates they are probably deficient in nitrogen. The lawn fertilizer 32-4-8 is high in nitrogen and will green up your lawn very quickly.

Phosphorus is important in the production of flowers, fruit and root development. We always recommend bonemeal when planting new plants and bulbs. This high phosphorous organic fertilizer is excellent for stimulating new root growth. Switching over to a higher phosphorous fertilizer (15-30-15) later in the season will promote more flowers.

Potash, or potassium, is a key element in disease, cold and drought resistance. We recommend not fertilizing with high nitrogen after mid August. This allows the vegetative growth to slow down and the root development to increase. Applying potash in the fall will help trigger the plant to go into dormancy and be better prepared for the oncoming winter.

Trace elements such as iron, calcium, magnesium, boron and copper are also important in the health of a plant. It is very difficult to detect which trace element your soil may be lacking. An easy solution is applying a mix fertilizer of fritted trace elements in the spring- this should cover all the bases.
