Question: 805-3312
We have a hickory that has not produced many nuts in the last two or three years. It is lush green and we have not fertilized in the last five years. Any suggestions? Doris, Norwich, CT

Mort's Answer:
Hickory trees have a very decided tap root that dominates the root system. Because ledge is so prevalent in your area and you have shallow water tables, your tree is likely to have used up the nutrient as it has grown larger. You will need to fertilize those fibrous roots that may be near the surface. A good supply of aged wood mulch applied each year will help retain moisture and any fertilizer that can be applied through the roots. Dig about eight holes in a circle around the tree. If you can drill with an augur, you can go down six feet or more. Fill these holes with 5-10-10 granular fertilizer. This should be good for five years.
