Q.Fertilizing Mature Citrus Trees

Anonymous added on April 12, 2011 | Answered

How do I know which citrus fertilizer is best for our 15+ year old orange and lemon trees? The greenery is plentiful and healthy looking on all trees except our mandarin orange, which is losing leaves like crazy. Do I choose a food with low nitrogen to improve the flavor and juiciness or high nitrogen? Low phosphorus or high?
