What to look for in a good fertilizer for lemon trees
Fertilizing lemon trees follows the typical protocol growers use to keep citrus trees healthy and strong. Citrus trees are heavy feeders; it is best to fertilize them every 4-6 weeks during their active growing season (spring and summer) and every 1-3 months during the dormant period (fall and winter). Lemon trees need a fertilizer containing a good quality source of nitrogen.
The nutrient ratio of fertilizers used to feed lemon trees should be no higher than 8-8-8 for optimum growth. These numbers found on a fertilizer label are the N-P-K ratio; the consumer can look at this ratio and determine the percentage, by weight, of the nitrogen (N), phosphorus (P) and potassium (K) in the fertilizer. In an 8-8-8 formula, a 10 pound bag of fertilizer would contain the following: 0.8 pounds of nitrogen, 0.8 pounds of phosphorus (in the form of P2O5), and 0.8 pounds of potassium (in the form of K2O).
All plants have essential nutrients needed for growth. Nitrogen is one of the main essential nutrients; its main responsibility in a plant is vegetative growth. It is used in the plant to construct amino acids which are the building blocks for protein; nitrogen is a major component of chlorophyll and helps to make the foliage green; and it is also necessary for the plant’s enzymatic reactions. Phosphorus is a component in DNA and RNA (the genetic building blocks within plant cells) and is needed for root growth and flowering. Potassium works more indirectly than the other two nutrients. It is not a component of any plant parts but activates many of the enzymatic reactions that occur within the plant, making it imperative for overall plant health.
