I have a variety of tropical fruit trees and also have a small flock of free ranging chickens. I'm wondering if anyone can recomend a liquid fertilzer for my trees? Most of the fertilizer sold at local stores is granular and with my chickens I can't use it or they will end up eating it and getting poisoned. So far I have used fruit tree stakes that you hammer into the ground. They seem to work ok but I'm honestly not that impressed with results.
