How to Grow a Citrus Tree Indoors
- Step 1 : Buy the right tree. Persian or Bearss Lime, Semi Dwarf Lisbon, Meyer Lemon , Citris Mitis Calamondin-Minature, Calamondin Orange, Improved Meyer Lemon, Panama Orange, Monachello Italian Lemon Tree, Eureka Lemon, Nippon Orangequat are all great varieties for beginning indoor cultivators.
- Step 2 : Soil needs to be the correct pH and promote proper drainage. A range of 5-8 is best. The soil should be loose enough to permit adequate but not excessive drainage. Any type of pot will do, but a 1" - 2" layer of gravel at the bottom of the pot will most readily promote drainage.
- Step 3 : Citrus trees require a minimum of 5 hour of sunlight per day. Ideally, they should get 10-12.
- Step 4 : Humidity. Citrustrees will drop their leaves if the humidity grows too low in an indoor environment. Ideal humidity should be at 45 - 50%. Use a humidifier, if necessary.
- Step 5 : Regular watering is necessary for your tree's survival. When the top 2 inches of soil are dry, water (but don't soak) the tree.
