Frequently Asked Questions

Does the Mexican Key Lime tree have thorns, or is there a thornless variety?

  • Yes, Mexican Key Lime trees have small thorns along their branches, reflecting their closer relationship to wild citrus ancestors compared to thornless Persian limes. The thorns are manageable and don't significantly impact harvesting or care. Wear gloves when pruning or picking fruit to avoid scratches.

How much sunlight does a Mexican Key Lime tree need daily?

  • Mexican Key Lime trees need full sun, requiring 6-8 hours of direct sunlight daily for optimal flowering and fruit production. In containers, place on a sunny patio during summer months. Shop at Nature Hills for healthy specimens that thrive in bright locations.

What type of soil is best for planting a Mexican Key Lime, and does it need good drainage?

  • Key Limes thrive in well-draining, slightly acidic soil with a pH between 6.0-7.0. Like all citrus, they're extremely sensitive to waterlogged conditions and will develop root rot in heavy clay or poorly draining soils. Use a quality potting mix for containers, or amend garden beds with compost and sand to improve drainage.

What are the watering requirements for a Mexican Key Lime tree after planting?

  • Water deeply but infrequently, allowing the top inch of soil to dry between waterings. Container-grown Key Limes need more frequent watering than ground-planted trees. Check soil moisture regularly during the first year while roots establish.

What fertilizer should I use for a Mexican Key Lime, and how often?

  • Use a balanced citrus fertilizer (like 10-10-10) with micronutrients every 6-8 weeks during growing season. Container plants need more frequent feeding since nutrients wash out faster. Reduce feeding in winter when growth slows, especially for potted trees moved indoors.

How is the Mexican Key Lime tree shipped, and what should I check upon arrival?

  • Key Lime trees typically ship as young potted plants, ready for transplanting or continued container growing. Upon arrival, check for healthy green foliage and inspect the root system if possible. Place in bright, indirect light initially and water if the soil feels dry to help it acclimate.
