Answer: Citrus does need a consistent supply of fertilizer. Try to find one formulated specifically for citrus and follow package instructions, or use a balanced fertilizer that also contains zinc, iron and manganese to keep up the micronutrients. Don't over fertilize; half-strength solutions are recommended if your tree is in a container. You could divide the total amount of fertilizer recommended into 3 separate feedings: one in Jan or Feb; another in April/May and a final in Aug/Sept. Always water thoroughly before and after applying fertilizer to prevent burn. Best wishes with your lemon tree!
