1. Choose the Right Type of Tree
Before we begin, it is important to ensure that you are growing the right type of lemon tree indoors. Meyer lemon trees usually grow well inside due to their small size and require less sunlight. They’re perfect for indoor gardening. You can also grow other types of lemon trees, but they require much larger pots and need more sunlight, and good airflow.
2. Choose a Large Pot to Plant In
Choose a container that is about twice the size of the root ball of the plant. The pot should have a drainage hole at the bottom to prevent waterlogging. Lemon trees also require deep soil, so make sure the pot is at least 18 inches deep.
3. Add Nutrients to the Potting Soil
Lemon trees require sufficient nutrients to grow correctly. Choose nutrient-rich potting soil to ensure that the tree receives enough nutrients. You can also add organic nutrients like compost, peat moss, or worm castings to the soil to increase the nutrient content.
4. Plant the Tree
Add soil to the pot and create a depression in the center. Remove the lemon tree from its original container and place the root ball into the potting soil. Fill up the space around the root ball with potting soil and press it down to ensure that the roots are in firm contact with the soil.
5. Watering
Water your lemon tree when the top inch of soil is dry to the touch. Don’t overwater the tree, as it can cause root rot. Allow the soil to dry out a bit before watering again. Also, don’t let excess water collect in the saucer beneath the pot. Drain off any excess water after watering to avoid waterlogging.
6. Light Requirements
Lemon trees require ample sunlight to grow properly. Place the tree in a location that receives at least six hours of direct sunlight per day. You can also use grow lights if you don’t have an area that receives enough sunlight.
7. Temperature
Lemon trees grow best in temperatures between 70-85°F during the day and 55-68°F at night. Ensure that the tree is not placed near vents or air conditioning systems as this can cause fluctuations in temperature.
8. Fertilizing
Feed your lemon tree with a citrus-specific fertilizer every three to four weeks during the growing season. Follow the instructions on the fertilizer package.
9. Pest Control
Keep an eye out for pests like spider mites, aphids, and whiteflies, that can cause damage to the tree. The best way to prevent an infestation is to keep the tree clean and healthy.
In conclusion, it is possible to grow healthy and productive lemon trees indoors with care and attention. Choosing the right type of tree, a large pot, nutrient-rich potting soil, and ample sunlight, while keeping the tree healthy and clean, will result in a beautiful, healthy, and productive plant.
