Calamondin Care

One thing you do should say to trees in general, they don’t need a lot of maintenance. Once established, the tree will find the moisture and nutrients it needs in the deep depressions of the soil. But the calamondin is just a small tree with a relatively shallow root system. So it will rely on you for watering and feeding. You will also need to take regular vigorous pruning of the tree to keep it in shape. Even more so, if you grow it in a container.


Whether you are growing the calamondin bush in a container or in the garden, the soil needs to be adjusted. Ordinary soil, even loamy soil, will not work with this variety. To give it a head start, dig a hole a foot deep and a foot wide and fill it with potting soil. Add organic compost and perlite in a 2: 1: 1 ratio in favor of the potting soil. Mix it well and let it sit in the sun for a few days before planting the citrus fruits. The pH of the soil should be slightly acidic, although you can get away with neutral pHs too. As long as you get a score between 6.0 and 7.0, your floor is fine.

Light and Temperature

If you have an orange tree in your garden, you can easily provide the necessary light and temperature for your calamondin tree. She prefers bright light, full sun and warm temperatures. In other words, the more tropical your microclimate, the better for these citrus fruits. As long as your daytime temperature doesn’t drop below 70 degrees F and doesn’t exceed 90 degrees F year round, you won’t have any problems.

If you grow it as a potted plant, keep it near a window facing west or south. Turn the pot a quarter turn every week during the growing season to prevent the canopy from looking crooked.

Calamondin care details


Although the tree gets almost all of its moisture needs from the top inches of the soil, it doesn’t like to over water. You don’t need to keep the soil moist all the time either, as this citrus fruit has a high tolerance for drought. And to encourage deep root growth, water the soil deeply but give it time between waterings. When the top inches of the soil dry out, your tree needs watering. Reduce watering when the weather cools. The water supply varies depending on the microclimate. If the summer is hot and dry, water the tree twice a week.


The calamondin is a powerful fertilizer. It needs a full-fledged citrus fertilizer throughout the growing season. Just make sure the fertilizer is soluble and apply it once a month. You can also dress with organic compost and aged manure. If the tree grows in a container, the citrus fertilizer will do. Water the tree immediately after each use to avoid root burns. If the tree is slow to flower, hold out watering and feeding until the leaves droop and wither. Then apply the soluble fertilizer and then pour vigorously.If the sun hits only one side of the tree, that side becomes lush and dense, and the tree becomes crooked.

This is more of a risk with potted plants where the tree could tip over. To encourage more even foliage growth, you’ll need to bring your trusty secateurs to the tree after the harvest. Focus on clearing paths for the sun and wind to get inside the canopy. Cut off one of two crossing branches and regularly remove any dead, damaged, or diseased branches. Pruning also allows you to change the shape of the tree. It could have a tall trunk or a bushy canopy of leaves, depending on how you prune it. If you want to give it a bushy look, pinch the tip of the top branch and encourage lateral growth. For a taller and slimmer canopy, cut off the side branches.

Pests and Diseases

Of the many pests that infest the calamondin tree, citrus burrs, scales, and aphids are those to watch out for should spray the tree with neem oil if you notice pest activity on the tree. Good air circulation and bright sunlight are important factors in keeping fungal infections at bay. This is another reason why you should prune your citrus tree on a regular basis.

Harvesting Calamondin

Your calamondin tree will begin to produce fruit in the first two to three years of its life. The lime-sized fruits are harvested from the moment they are green until they are fully ripe. The harvest season begins in November and lasts until March of the next year. To cut the fruit, hold it with one hand and cut off the stem with sterilized scissors.

The fruits can be stored for months at room temperature without losing their taste or sour taste. However, if you want to extend its shelf life, cut the fruit with an inch of stalk on it. The stem continues to feed the fruit, preventing it from wilting too soon.
