Answer: Without more information on the location, weather conditions, soil type and fertilization habits, it’s hard to venture a guess.
Here are some conditions I have read about that will affect the juice production of citrus trees in general.
- Citrus trees do like to have a good consistent moisture level and so it is recommended they have a drip irrigation system around the root area of the tree. There are several mineral elements that have positive and negative effects on the juice content. Nitrogen will increase juice content and acid concentration, but can also increase the peel thickness. WIthout the proper balance of all major nutrients, nitrogen, phosphorus, potassium and magnesium, fruit quality and yield are affected. Before arbitrarily adding any fertilizers, I would highly suggest having the soil tested by a qualified lab that can also test for the micronutrients boron and copper.
- If your soil tests OK and the water levels have been sufficient, then I would check with your county extension office for the possibility what type of pests might be affecting the quality of the fruit production of the plant.
I hope this gives you some direction, and may you have many juicy limes next season. Karen
