Using time-release (or controlled-release) fertilizer is like taking a vitamin tablet. If we always ate a perfect, well-balanced diet, we wouldn't need it. Unfortunately, few of us eat as we should. As a result, if we didn't supplement our diet, we would be deficient in certain vitamins and minerals

By the same token, when fertilizer is broadcast around trees, there's no way to know how much of it reaches the trees' roots. Using Nutrapro solves this problem because it's placed in the hole alongside the tree's roots.

Nutrapro has been specially formulated for trees and shrubs (16-8-8). It comes in a plastic package with micro-pores that allow the fertilizer to be released into the soil at a controlled rate (as moisture transfers thru the pores). The contents (NPK) are dissolved over time by water vapor entering the package through these micro-pores.


Nutrapro comes in two strengths: One supplies key nutrients for one to two years, the other for three to five years. During these periods trees usually experience an increase in growth rate by up to 25 percent.

Nutrapro eliminates the danger of burning the roots of young trees. Best of all, it doesn't contaminate ground water and requires no measuring, mixing or clean-up.
