Calamansi is one of the citrus fruits that are used in cooking. For example, it is added to a dish called Mexican cuisine as a key ingredient. In addition, most of the ingredients used in the preparation of this dish are citrus fruits such as calamansi and lemon. The calamansi fruit is also known as kalamansi, calamondin, and kalamansi lime.

The calamansi is known for its many domestic uses. It has been used to cure a sore throat and insect bites. It also is a great cleaner for removing stains from fabric. If you’d like to grow a calamansi indoors, you can plant it in a container or landscape and enjoy the fragrant fruit of this fragrant tree. Known as the calamondin, this small evergreen is native to the Philippines and other warm tropical regions.

It is very important to give proper care to the plant once you have planted it in your garden because it will take a long time before it can bear fruits. Because the plant is only ready to bear fruits after more than 10 years, caring for the plant properly will determine how fast and how good your fruit can be.

To begin with, you should know that there are two kinds of calamansi plants; those that grow to be tall plants with thick stems and those that grow shorter plants with thin stems.

Indoor Management Of Calamansi Plant

If you are wondering how to take care of a calamansi plant indoor, you’ve come to the right place. In this article, we’ll discuss watering, fertilization, pruning, and temperatures. Once you have your plant, you can easily follow the instructions below. And don’t forget to read the article’s other articles for more useful tips. Here are some of the most important tips to remember:

Watering and Light requirement

One of the most important parts of caring for a calamansi plant is maintaining the right humidity level. Ideally, it should have a relative humidity of 70% or more. When you water a calamansi plant indoors, make sure that the top inch of the soil remains moist. Your calamansi needs at least 6 hours of sunlight per day. While LED lights can simulate sunlight, natural sunlight is preferred.

Choosing a location for your calamansi plant is essential to its survival. It should get at least six hours of direct sunlight a day, and it should not be blocked by the door, window, or furniture for more than a few minutes each day. Moreover, the Calamansi tree should get plenty of water, although you should avoid daily watering, as it could lead to soil waterlogging and rot.

Depending on the variety you have, a container with a drainage hole of 16 inches is ideal. You should use a potting soil with a pH of 5.5 to 6.5. You should also provide the soil with some catalyst to promote plant growth. Alternatively, you can use a nutrient-rich loose soil mix. If you are not able to find a suitable substrate, mix leafy bog soil and coarse sand in a 3:1 ratio. Just be sure to turn the pot regularly so that the water remains at the same level.

As with all citrus, calamansi needs abundant light to thrive. As such, it is best to place it in a sunny window with direct sunlight. The tree also needs lots of water and potassium fertilizer. However, unlike other citrus species, calamansi trees do not need much feeding during the winter season. For best results, you should water your calamansi plant at least once a week.


Fertilizing Calamansi Plant indoors requires a high-quality soil with good drainage and good aeration. Organic material like wood chips or dry leaves should be spread around the plant’s trunk and drip line. You should also leave about an inch of space between the mulch and the trunk to discourage weeds. Calamansi plant indoors should be grown in a spot with good sunlight and adequate drainage.

In addition to watering, calamansi plants need fertilization once every four months. Using a 16-20-0 fertilizer containing urea, apply 2 to 3.5 ounces of fertilizer to the soil. Water the plant thoroughly and repeat every two or four weeks. Water a calamansi indoors once a week, until the leaves begin to yellow.

In addition to watering and fertilizing regularly, you should also provide partial shade, as this can prevent the fruit from producing. For best results, make sure your calamansi plant is growing in a well-drained soil rich with organic mulch and a moist environment. If you’d like to grow your own calamansi plant, you can start with a seedling or a rooted cutting. You can use organic fertilizers and even remove the tree’s horns if necessary.


You can prune a Calamansi plant indoors, as long as you do it between February and April. Do not prune your plant during the summer as the temperature will increase. Also, it will be more susceptible to drought during these months. A humidifier or tray of wet kleenex is a good alternative. Make sure that the water is soft and at a temperature 10 degrees warmer than the substrate.

Before you begin pruning your tree, you should identify which branches are dead or diseased. Those branches should be removed to allow the plant to receive more nutrients and water. You can use pruning shears, which are available in different colors and prices. The best choice will depend on the size of your tree. If it is smaller than your living room, you can use scissors. But remember to avoid damaging the plant by clipping it too hard.

You may also consider pruning your calamansi tree during the winter season. During winter, do not cut off the topmost branch. This will prevent your plant from putting on too much growth. You can use hand pruners or a tree lopper to trim off the topmost branches. For larger branches, you can use a tree sower. You can also try pruning the plant by pinching off the lower leaves.

The best time to prune a Calamansi plant indoor is in the spring. It is essential that you look at your plant from all sides before deciding on the basic shape of your plant. You can either prune your tree into a miniature orange tree, an espalier, or a bushy shrub. In either case, you should carefully consider the size and shape of the branches before making the first cut.


In order to take care of a Calamansi plant indoors, you need to provide it with the right temperature and humidity. Watering the plant once a week should be sufficient, but it should be watered more frequently during spring and summer. During the dormant period, it should be kept slightly below 50% humidity. Watering the Calamansi plant in between waterings should be done when the top two inches of soil is dry.

The perfect climate for a calamansi plant is a temperature of 70 to 80 degrees Fahrenheit, with temperatures no lower than 20 degC. It is best to avoid sudden temperature fluctuations and to monitor the humidity with a humidifier or a tray of wet kleenex. The water should be a soft consistency, about 10 degrees warmer than the substrate. If you are not sure, place the plant in a semi-shaded area. The plant’s humidity needs are minimal, but it requires constant care and monitoring.

The ideal temperature for a Calamansi plant is between 70deg and 90deg Fahrenheit. It can survive in temperatures as low as 20deg F but needs a constant temperature range. The best temperatures are between 70-80 degrees Fahrenheit during the day and 65-70 degrees at night. If the temperatures drop below these ranges, the plant will go dormant for about a month.

While it may look dry and lifeless, your Calamansi tree needs lots of water. Ideally, it gets about 6-8 hours of direct sunlight per day. It also needs frequent feeding with a balanced fertilizer that is high in potassium, phosphorus, and nitrogen. If you want to keep it healthy and productive, you should hand-pollinate the plant to avoid a dead plant. You can use coffee grounds and tea grounds as mulch near the trunk. Never throw out coffee or tea grounds – they contain a lot of valuable nutrients that your plant needs.


Calamansi plants require hand pollination to produce a high-yielding crop. During their dormant season, calamansi trees do not require much feeding. If you are growing a potted plant indoors, make sure the soil stays moist to one inch below the top surface. Calamansi plants also need constant sunlight – ideally at least six hours per day – and abundant watering.

Once the plant is in a pot, it will need to be repotted every few months. The process is slow and gradual. Afterward, the plant will need to be repotted as it grows larger than its pot. The most common pests and diseases that affect indoor calamansi plants are pit scale and citrus leaf miners. Aphids and ants are common problems as well. The disease citrus gummosis is the most common.

A calamansi plant can take up to three years to bear fruit. Once mature, a calamansi plant requires regular repotting. When starting a new calamansi plant indoors, remove the seed from a fruit and put it in a moist cloth. Wait for three days, and the seedlings will begin to emerge! So, don’t wait too long. The fruits of the calamansi plant are worth the wait!

In conclusion,

The calamansi tree can be grown indoors or outdoors. Although it prefers warm climates, but it can be grown in moderate climates and even cold weather due to its wide adaptation. However, you must keep in mind that the plant requires humid air and high temperatures to thrive well. It grows best when fed with organic fertilizers such as fish emulsion, vegetable fertilizers and bat guano. As these fertilizers contain nitrogenous materials which boosts the growth of the plant then you need to use them regularly. You can also use organic lime powder made from lime stone to feed your plant.
