Indoor Citrus Trees: 5 Tips For A Healthy Vibrant Tree

If you’ve discovered the joy of growing an indoor fruit tree, you’re likely very pleased with their low maintenance. Just about anyone can grow these dwarf citrus trees in just about any living space. Their fragrant blossoms and sweet delicious fruit make them a welcome addition to any home.

Here’s 5 tips for making sure your indoor fruit tree is healthy, vibrant, and productive:

1. If you need to add soil to your tree container, never use soil from the yard or anywhere outside.

Get a soil mixture with perlite mixed in. You can buy this mix online or at most garden centers. The soil mixture should be an airy potting soil, and you should add soil up to the line on the trunk where discoloration from the dirt used by the nursery ends. Leave enough space at the top of the pot to water thoroughly.

2. These miniature citrus trees like regular watering.

For the most part, every week to 10 days is plenty. When the soil is no longer damp, go ahead and water. Be thorough but don’t drench the soil. As for light exposure, a western or southern exposure is best.

3. Not only do indoor citrus trees like water, they like to be fed as well.

Once a month, fertilize them with a specially formulated fertilizer made for indoor citrus varieties. If you don’t want to buy a specialized fertilizer, no worries. The key ingredients are zine, iron, and manganese. Most good quality multipurpose fertilizers contain these ingredients.

4. Most humans hate humidity, but as you might imagine, indoor citrus trees love it.

If your living space is dry, particularly in the colder months, add moisture with a humidifier, or mist them frequently. Another good idea is to place your tree container in a tray filled with pebbles and water added to the top of the pebbles. Note of caution: Don’t put your tree directly in front of a drafty vent.

5. When it gets warm outside, give your tree some TLC and let it live outside on a patio or balcony.

The outdoor sun will do your tree good, but acclimate it to full sunlight gradually. We usually place our three trees in a shady area for a few days first.

Other Tips

After you’ve owned your tree for a while, you’ll notice it will produce quite a number of blossoms. Not all of these blossoms will produce fruit, but you can help encourage fruit production. Take a soft small paintbrush and brush the stamens of open blossoms from blossom to blossom. Basically, you’re helping the pollination process.

Lastly, for pests, spray your tree with horticultural oil. Your most common pest will likely be spider mites. Horticultural oil will smother the pests and should rid your tree of the problem. In fact, regular misting will deter pests, and misting your tree every other day or so is something we wholeheartedly recommend.

Misting provides humidity for your tree, which they enjoy. Just use a regular spray bottle with the nozzle setting on mist or fine (the mist should be gentle). Use tepid water, meaning not hot or not cold. But in the rare instances your indoor fruit trees experience pest problems, a spray of horticultural oil every other day will definitely rectify the issue …

  1. I’ve grown some big lemon trees. They are 13 years old and keep them indoors in the winter, on the front porch in summer. I had one tree bear two lemons but the other two would get a few blossoms and they would only drop off despite the fact that I would pollinate them. I fertilized with some citrus feed I got in Arizona last fall. I am not getting any blossoms any longer. Any help would be appreciated. The trees are 10 feet tall and were getting too bushy so last July gave them a “haircut!” They are healthy and have nice green leaves but no blossoms or fruit. I water them once a week. I will try misting and see if that helps. Thanks!

    Hi … one suggestion I have is to check for what are called “suckers” on the trunk of the trees that don’t produce fruit. This is usually the cause of blossom drop on these types of trees. A sucker will look like a knot or nodule on the trunk below the lowest branch but above the soil level. Most times this will resolve the problem … it sounds like you’re doing everything else correctly for years!
