Tons of varieties exist when you go hunting for lemon trees. When planning to grow it indoors, you should be looking for the compact ones that will adapt well to container gardening. Specialists at local nurseries will easily guide you on the best varieties for your particular climate and indoor environment. 

Most indoor gardeners, however, prefer growing Meyer Lemon Tree in pots. It’s a dwarf tree that grows well in containers and produces many small to medium-sized lemons with little maintenance. 

Eureka, dwarf Ponderosa, and Lisbon are also popular picks for indoor lemon gardening. No matter which variety you pick, make sure you get one that’s about 2 to 3 years of age since younger plants are less likely to survive indoors.

While lemon trees aren’t excessively high maintenance, getting one and forgetting it in a corner of your house wouldn’t help grow a lemon tree indoors. Some effort is needed if you want to see it laden with those bright, juicy fruits. Once you’ve received the right variety of tree, here’s what you do:

Pick the Right Pot for Your Lemon Tree.

Too small a pot will inhibit the development of plant roots, resulting in stunted growth. A larger size pot is usually a good choice if you want an optimally sized lemon tree in your living room bearing a decent amount of fruits. 

Make sure the pot has drainage holes at the bottom and include a saucer below it to catch excess water without damaging your floor. Also, include a bunch of pebbles or gravel to the saucer to create a humid environment, suitable for lemon trees.

Choose good soil

Choose nutrient-rich, well-drained, acidic to mildly acidic soil to fill the plant pot. Cactus mixes and peat moss soil mixes also do well for citrus trees. 

Repotting

Fill the pot halfway with the soil mix you’ve got. Once you’ve prepared its new home, gently take out the young tree from the nursery pot, scrape excess soil clinging to the roots, and place it in the pot. Add more soil to cover the roots. Make sure you plant it at the same level as it was growing in the original container. Water it right after planting.

Choose a sunny spot

Lemon trees ask for around 10 hours of direct sunlight every day. Place them next to a sunny window or grow it under artificial lights. Leave the lights on for 12 hours each day for optimal results.

Water

Maintain consistently moist soil for your lemon tree but avoid waterlogging. Offer it a drink once a week; if you find curled edges on the leaves, it suggests that the plant is thirsty. If you get hard water in your area, mix 1 tablespoon of vinegar to 4 gallons of water before giving it to the plants. This will lower the pH to suitable levels. 

Fertilizer

Feed your lemon tree with a nitrogen-rich fertilizer once every month during spring and summers, and once every two months for fall and winters. A 2:1:1 NPK fertilizer works best for citrus trees. 

Ventilation

Indoor lemon trees grow best when conditions are similar to the conventional outdoor setting. Set up an oscillating fan nearby or leave a door or window open to allow air circulation around the plant.

Temperature

A daytime temperature of 70°F and a nighttime temperature of 55°F is ideal for the tree. Keep the plant away from drafts, radiators, and fireplaces to ensure it grows at its optimal rate.

Manual pollination

When you see flowers on the tree, it’s time for pollination. However, since there aren’t any birds and insects indoors to move pollen, you’ll have to do it by hand. Even if you have self-pollinating varieties, a little extra help will ensure that the tree bears plenty of quality lemons. Collect pollen from the stamen using a cotton swab or a paintbrush and transfer it to the stigma (located in the center) of another flower. 

Harvest

Once flowers appear, it will take 6 to 9 months for lemons to mature enough to be harvested. Once the fruits turn a rich yellow color and are soft to press, it’s time to pluck them off. See if you are want to grow a lemon tree indoors it is not as hard as you thought.
