Is manure (cow, horse, chicken) good fertilizer for citrus trees?
As long as it is well composted, it is good. I would use the chicken manure lightly though. It is high in nitrogen and this may cause the tree to produce less fruit.
I have some extra ornamental/shrub fertilizer and would like to use it on on the citrus trees I have. Any reason not to use it? I know it is not as beneficial, but will it help?
It will help and be fine for the tree. The citrus fertilizers tend to be higher in acid, but that is not essential to the health of the plant.

I have had great success with lemon trees with: water, feed with liquid manure, usually comfrey, mulch with seaweed, stable straw or horse manure and water again. I do this 3 monthly. Be very careful that mulch does not touch the trunk.

I live in northeast FL and have citrus trees. I covered the trees but too late. We had a heavy freeze and now the leaves are shedding but the trunk looks healthy. Now what?

If the stems are still alive, the leaves will regrow shortly.

I live in San Jose, California and I am wanting to plant some citrus trees in containers. I am having difficulty locating a local source where I can purchase large resin or fiberglass containers large enough to plant a tree in. Do you have any suggestions?
Believe it or not, Wal-Mart often carries containers of a sutible size for this. Hardware stores as well, once the growing season is in full swing.
I would like to know the best fertilizer formula; for example, 10-10-10, for my citrus trees in south Georgia.
