How to fertilize pecan plants?
Pecan
None Given
Hi there!
I'm from Center Italy and I have two 2 years old pecan grafted plants.
I would like to fertilize them with chemical fertilizers.
I can use a 15-9-15 slow release fertilizer.
By reading online I found different opinions about the quantity to use.
I have no idea about pecan needs so I thought to use the same quantity used for walnut.
So according to the label, I should use about 300g (0.66 pound) per plant of 1 year and 300g (0.66 pound) + 100g (0.22 pound) for every consecutive year.
So the next spring I should use 400g or 500g (0.88-1.1 pound).
I should give it in three times, in February, in May and in September-October.
By reading some pdf of USA University, I found that it is possible to use a 10-10-10 slow release fertilizer:
310g (0.68 pound) in February/March and 310g (0.68 pound) in June
Every consecutive year add other 0.68+0.68 pound.
According to you, by considering that I'm going to use a 15-9-15 fertilizer, how many grams should I add?
p.s.: I'm going to spray also zinc sulphate.
I calculate to give about 5-10g/l of zinc sulphate @ 20%.
