Sour Lime Fruit

Question

Our lime tree produces fruit that is too sour. Is there a soil amendment to help make the fruit less tart?

Answer 1

Citrus fruits tend to develop their sweetness later and limes are suppose to be harvested unripe as it is. Harvesting a little later (but before they turn yellow) should help. Trees also produce sweeter fruit when they have ideal conditions. So make sure to provide it with adequate fertilizer and plenty of water. Growing lime trees in good, well-draining soil is also important, so adding some compost to the soil should help alleviate any current issues that may be present.
