Hi Gerry, thank you for your advice recently about watering my horse chestnut trees. it seems to have stalled the dying leaves however i was just wondering from going through the website you seem to recomend not feeding some trees and feeding others. would there be any use in feeding my horsechest nut to help them along and why would i not? also these trees are incorportated in a lawn and therefore have grass up to the base of the tree should i spray around the trees and limit the competition from the grass? someone suggested that i should root with a stake wround the trees and pour water into the holes to allow extra water down? thanks
There need to be signs of new growth before feeding, and then feeding will help. Weak trees might get a liquid feed as a small boost, but otherwise feed in spring with tree and shrub fertilizer or general fertilizer, but only on poor soil. Trees do not need feeding in good fertile ground.
