How To Grow Lime Trees Indoors

Lime trees are very easy to grow since they have very simple needs. And you must attend to this if you are aiming for a beautiful indoor lime tree. 

  • Watering. Water your plants as you do with other plants. But make sure your pot has good drainage. While lime trees need water, they don’t want to get soaked in too much water. 
  • Soil. Lime trees can grow well in medium to large pots that are wide and deep. For the best result, use a lightweight, perlite-containing potting mix. Perlites can help drain the water faster and prevent waterlog from building up. Normally, there is the potting mix that is specifically sold for lime trees. You can look for this in your local nursery or you can buy it online. 
  • Pruning. Young dwarf lime plants do not need much pruning. Give them a few years until they have fully grown and become bushy. When they have established and grown sturdy, you can prune them to tidy them up. You also need to prune deadwood to maximize airflow. Also, prune off branches that cross others and prevent light from reaching the lower branches. 
  • Feeding. If your dwarf lime tree appears to require nutrients, look for citrus or lime tree fertilizer. This will help keep things growing.
  • Pest and diseases. Indoor citrus trees are prone to pests. In this case, we suggest that you use natural means to get rid of pests. As always, prevention is better than cure so when it is pest season, you can rub neem oil on your plant’s leaves. However, if you find that your plant is attacked by mealybugs and spider mites, just use soap and water to remove them.

Lime Tree Care And Tips

  • Expose it to at least 6 hours of direct light every day. Otherwise, you may want to use LED grow light if necessary.
  • Keep indoor temperatures between 55 and 80°F, and lower the thermostat a few degrees at night.
  • Move plants outdoors in the spring to help them develop. But protect them during cold weather days by keeping them inside.
  • Avoid abrupt changes in light exposure or temperature. Water regularly but make sure that the soil also drains well. Keep the soil moist but clear waterlogged. 
  • Feed your plant regularly with a granular fertilizer. It ensures a sufficient supply of nutrients.
  • Prune the foliage after harvesting fruits to maintain the desired shape. 
  • Keep your plants indoors if it is too windy outside.
