Fertilizing Trees

Question

I am planting nine 8-ft. tall spruce trees using a 200 gallon tank. How much fertilizer do I add to the water tank?

Answer 1

That is going to depend on what fertilizer you use. The package should have directions, either measurement/gallon of water, or weight/sq ft. In the latter case, you would determine what area you will cover with the water, and put the appropriate amount of fertilizer in the tank.
