Though growing citrus in pots in the north isn’t easy, it is very rewarding. Imagine harvesting your own Meyer lemons, Bearss limes, and Satsuma or Calamondin oranges! Yes, they require a bit of care, but indoor citrus is oh so worth it. And here’s the kicker: Even if you never manage to harvest a single fruit, citrus plants are worth growing simply for their amazingly fragranced flowers and beautiful, glossy foliage.
To grow gorgeous citrus plants of your own, follow these steps.
8 steps to growing citrus in pots
Step 1: Start with the right variety. The citrus varieties I mentioned above are particularly suited to container culture because they don’t grow as large as some of the other choices. Source a mature or semi-mature plant from a greenhouse that specializes in citrus. Online companies will ship directly to your door. Do not purchase a plant that’s already in flower or bearing fruit. If you do, all the flowers and fruit will probably drop as the plant acclimates to its new location.
Step 2: Location, location, location. The biggest mistake folks make when growing citrus in pots indoors is not giving it enough light during the winter months. Choose a very bright room and keep the plant away from doors that open frequently, or use a grow light like this one. You’ll also want to keep it away from heat registers.
Step 3: Regularly water. Citrus like consistent moisture. Prolonged dryness can lead to bud, flower, and fruit drop. However, don’t go over-board on the water. Too much can cause the leaves to wilt and turn yellow. Water your citrus plant in the sink if possible. Let the water flush through the pot, and then allow the soil to fully drain. Be sure the base of the pot is never sitting in water.
Step 4: Play pollinator. Citrus tend to bloom in the winter, when the plant is inside and no insects are available to pollinate the flowers. If your plant comes into flower while it’s indoors, use an electric pollination tool to move the pollen from flower to flower on each plant. This necessary step is often skipped by those new to growing citrus in pots.
Step 5: Give it some summer lovin’. During the summer months, move your citrus plant outdoors, onto a patio or deck. Position the pot so that it receives morning sun until about one in the afternoon. You’ll want the plant to be in the shade during the hottest part of the afternoon to avoid leaf scald and heat stress. Keep it regularly watered and avoid allowing it to completely dry out.
Step 6: Fertilize. During the growing season only (from late March thru early August), fertilize your citrus plant with a liquid, organic fertilizer – such as liquid kelp, seaweed, or fish emulsion – every two to three weeks. Do not fertilize in the winter when new growth should not be encouraged. You may also want to use a small amount of organic granular fertilizer in late March to encourage new growth at the start of the season.
Step 7: Don’t panic! It helps to be aware that, like many other tropical plants, citrus will often drop many or even all of their leaves when moved either outdoors at the start of the season or indoors at the end. This leaf drop is natural. It’s the plant’s way of adjusting to different light levels. New leaves will develop that are better suited to the new light levels. Just give the plant time.
Step 8: Move it back inside. In the fall, when nighttime temperatures drop into the 50’s, it’s time to move your citrus plant back indoors. Again, select the brightest location possible and be careful to avoid cold drafts.
