Organic Fertilizer For Boxwoods
I am hoping someone here can tell me what type of non-chemical fertilizer I can use for my Boxwoods.
They were looking great right after winter. I am in Zone 8b so no snow, but it does freeze every so often. Anyway, they were busting bright green and now I am noticing that the older leaves on the inside are turning yellow!!
Doing some research I have found out it is a nitrogen deficiency, (hope that's correct) but I would like to use a non-chemical fertilizer.
Any advice is appreciated.
PS would anybody know why my one boxwood that is near the foundation of the house is so much bigger and nicer looking than the others? Is it something in the cement/brick that leaches into the soil or what??
(I will post the last question in the shrubs forum also looking for more hits):-)
