Planting Limes
Location and Climate
Limes thrive in warm, subtropical to tropical climates. They need full sun and well-draining soil.
Planting Time
The ideal time to plant lime trees is in the spring, after the threat of frost has passed.
Soil Preparation
Limes prefer a pH between 6.0 and 7.5. Amend the soil with compost to ensure good drainage and fertility.
Caring for Lime Trees
Watering
Regular watering is crucial, especially during dry spells. However, avoid overwatering as this can lead to root rot.
Fertilizing
Use a balanced, citrus-specific fertilizer. Apply according to package instructions, typically every few months during the growing season.
Pruning
Prune to shape the tree and remove any dead or diseased branches. Light pruning can be done any time of the year.
Pests and Diseases

Harvesting and Using Limes
When to Harvest
Limes are usually ready to harvest when they are slightly soft to the touch and a vibrant green color. They do not continue to ripen once picked.
Storage and Usage
