fertilize young trees
I've got plenty of 6' (6 foot) young trees. They have been in the ground for two or three years. I am fertilizing some of the hollies and Green Giants, but in general... is it important to fertilize young trees?
How fertile is clay? It is very dense (I dig holes with a pick ax for crying out loud), but is it nutrient rich?
Are there side by side studies of unfertilized trees next to fertilized?
I try to avoid fertilizing especially if the difference is subtle.
