Growing Calamansi (a.k.a. Calamondin)

Calamansi or calamondin (Citrfortunella microcarpa) is a fruit tree native to the Philippines. It is the most commonly grown backyard tree among the citrus species. It can thrive in a wide variety of environmental conditions.

It is a small tree with a height ranging from 2 meters to 7 ½ meters at maturity. Its broad egg-shaped leaves are dark green in the upper surface and pale green underneath. The fruit is round, about 2 cm to 4.5 cm in diameter, and greenish – yellow in color.

Like its relatives, such as the mandarin, pomelo and sweet orange, the calamansi is rich in phosphorous, calcium, iron and Vitamin C or ascorbic acid. It is the most popular and most commonly used citrus fruit in the country. Its juice is nutritious and traditionally made into a fruit drink that helps prevent respiratory diseases. It also helps strengthen the bones and stimulate growth especially among growing children. It can be used as a flavoring ingredient in desserts, e.g. leche flan, or as an additive in various food preparations, such as fish steak. Its pulp is used as a major ingredient in beverages, syrups, concentrates, and purees. The peel is made into jams, candies, and marmalade. With its alkalinizing effect, on the body calamansi helps circulate blood evenly and facilitates normal digestion.

Filipinos can have a year-round supply of this versatile citrus fruits by growing the plant right in their front yards or backyards or even in big boxes.



It is easy to cultivate calamansi. This plant grows well in cool and elevated areas and in sandy soils rich in organic matter. Waterlogged areas are not suitable for cultivation because calamansi plants cannot tolerate too much moisture.


Calamansi can be propagated by seeds, still, it is much better to grow this citrus crop using its vegetative parts. It is best to buy planting materials from reliable sources, particularly from the Bureau of Plant Industry (BPI), or government agency under the Department of Agriculture.


Establish the planting materials at the start of the rainy season. Dig a hole, at least 40 cm wide and 40 cm deep. Set the seedling into the hole and put back the dug soil mixed with compost. Water the plant daily, at least every morning.


The usual distance for planting calamansi is five meters between plants.


To produce big, luscious fruits, it is recommended to fertilize the plants regularly. Apply 50 g to 100g ammonium sulfate or urea, around each tree one month after planting. Do this every four (4) months but on the second year, increase the amount of fertilizer to 200g or 300g. Use the same kind of fertilizer per tree every four months thereafter.

The tree bears fruit on the fourth year, it is best to apply complete fertilizer, like ammophos and potash, to increase fruit yield at the rate of 500g per tree. At eight (8) to ten (10) years old, apply more fertilizers to the trees, from two to three kg per tree, three times a year. First, during the rainy season before the flowering stage; next, two months after flowering, and last, after harvesting.

To properly apply the fertilizer, mix it with the soil. It is also good to cover the soil around each tree with dry leaves to conserve moisture. Weed from time to time.


To keep the trees healthy and allow them to attain maximum yield, it is always best to protect them from pests and diseases. Pests in calamansi are easy to spot. Zigzag marks, savoyed cuts, and rugged edges on the bark indicate that the tree is infested with citrus bark borers. These are light brown or bluish-black beetles that lay their eggs in the cuts and cavities of the calamansi bark. When the eggs hatch, the larvae feed on the bark and leaves.

To control the citrus bark borers, spray the trees with pesticides recommended for citrus trees. To prevent the pest from spreading, cut off the infected parts and burn them.

Another harmful insect pest is the aphid. This greenish or brownish insect not only retards the plant’s growth, but also acts as a disease carrier. To control, spray the trees with pesticides recommended for aphids but if the pests have already attacked, cut off the infected parts of the plants and burn them.

Other harmful pests of the calamansi are the Purple Scale and Glover’s Scale. These pests suck the tree’s sap until its leaves and fruits wither and fall, and the tree finally dies.


Aside from pests, the calamansi is also prone to diseases, such as gummosis, citrus canker, and citrus scab. Gummosis is caused by either a lack of, or an excess of fertilizer, or damage from insect pests or machinery. The disease is marked by a dark sticky substance or gum oozing out of the infected branches and trunk. As the disease worsens, gum secretion increases. It is recommended that as soon as this gum-like substance is noticed, spray the trees with chemicals especially recommended for gummosis control. Apply the chemical directly to the diseased bark.
Citrus canker, a disease caused by bacteria, is characterized by raised lesions and glazed margins, with an oily appearance. Citrus canker affects the leaves, twigs, branches and the fruits. To control the canker, spray the trees with fungicide solutions when the trees area at dormant stage. Consult the dealers of fungicides for proper application of the chemicals.

Citrus scab is a disease caused by a fungus. It starts as a small pale-orange, somewhat circular, elevated spot on the leaf. A severely infected leaf becomes so distorted, crinkled and stunted that whatever remains has very little semblance to a normal leaf. To control this disease, spray with a copper fungicide solution. Following the manufacturer’s recommended application or formula. Spray when new flushes of growth have developed, or during blooming stage when two-thirds of the petals have fallen and, also two weeks thereafter until the fruits are half mature.


Calamansi trees will start to bear fruit one or two years after planting. To harvest, pick the fruits from the branch, either by hand or by using a pair of scissors. Take extra care to prevent damage to the branches or to the leaves. To keep the fruit fresh, leave a portion of the stem attached to the fruit and avoid injury to the skin when harvesting.



* Use freshly harvested mature calamansi
* Wash and drain
* Cut across the upper portion to avoid cutting the seeds
* Squeeze out the juice by hand or use a fruit juice squeezer.
* Strain
* For every part of the juice, add 1 13/4 parts sugar (60oB)
* Stir to dissolve the sugar.
* Allow to stand undisturbed for three (3) days, preferably in a refrigerator
* When the fruit pulp and other fruit sediments have floated and the clear calamansi juice has settled, this clear solution is called the calamansi nip.
* Siphon the nip into a dry sterile, narrow mouth glass bottle with a stopper.
* Fill containers completely
* Refrigerate at 50oF or below.


* Select big, green calamansi fruits
* Cut slits in the lower end of the fruit to extract the seeds and the juice
* Soak the de-juiced fruit in water overnight
* Boil in a copper vat with enough water
* Remove from the fire when the natural green color of the fruit has set
* Soak again in water for three (3) days but change the water often.
* Boil in plenty of water three or 4 times but change the water after boiling
* Drain
* Cook in syrup (2 parts sugar to 1 part water) for 15 minutes. Soak overnight
* Boil in the same syrup until it begins to thicken.
* Drain syrup
* Pack calamansi in jars and pour strained syrup
* Remove bubbles, refill, half-seal, and sterilize 12 oz jars for 20 minutes in boiling water

    Hello, I have a 25 year old Calamansi tree here in Northern California, All of a sudden within a 3 week period, the tree dried up and all the leaves turned brown. The leaves did not fall off. Is this normal for an old calamansi tree? Thank you for any help. I have to explain this to my dad who planted this tree 25 years ago and he’s coming back in 3 weeks. I hope I can explain wht happened.

    Thank you,

    I grow a calamansi plant from seed.However, after few months the plant grow to 80cm but now fruits yet. It also had torns along its branches. I bought a calamansi plant to see the difference.No torns and fruits are growing at only 50cm tall.Is my plant that I grow from seeds cannot bear fruit?
    Let me know

    The plant that you grow from seeds will take longer time to bear fruits depending on how you care for it, the soil,and the climate, ideally
    it could bear fruits within 3-5 years. On the average if planted outside it should bear fruits
    within 5-10 years. The one you bought that has no thorns are marcotted. I don’t have the scientific expalantion why marcotted ones has no thorns. this is my observation from my own experiences for more than 20 years growing calamansi from seeds and marcotted in pots or in the ground. I have grown from seeds indoor in pots that bearfruits after 10 years.

    Good day,
    I have a farm in Bacolod recently converted from sugarcane to coconut trees intercropped with calamansi. To maximized the area, i planted my calamansi at 3m apart using triangular method of planting. Is it just the right spacing?
    One more thing, i am using the marcotted planting material for calamnsi and in fact it started to bear fruit though it’s still in the poly bag and not yet field planted. I manually pick out the flowers to delay fruting and to avoid breaking of branches. I only wanted to know what is the ideal age of a marcotted calamansi before it will be allowed to bear fruit?
    Any help/comments will be appreciated.
    Thank you and regards.

    I’m looking to buy fresh calamansi fruit in the U.S. I’m also interested in growing my own calamansi tree but considering that they can grow to up to 20 feet tall, I think I’ll have so trouble growing it in my apartment. Besides, I can’t wait two years for the fruit right now. I need the fruit now. But lest the wrong people reply (if there are any replies), I’m not interested in calamondin oranges. I need Philippine calamansi fruit, which starts out as green and then turns yellow. It’s more of a lemon as opposed to calamondin oranges and is about the size of a cherry tomato. I’ve had a lot of them during my numerous visits to the Philippines. Does anyone know where I can buy the fresh fruit? That is what I need most right now (about 80 fruit should work for what I need them for).

    I live in Phoenix, AZ and I’m trying to grow a calamansi tree. I planted it in Jan. 2011. It was fine until the heat hit us. The leaves dried up and fell off but the branches and trunk are still green. I water everyday because of the heat. What do you suggest I do differently? The tree was two years old from a nursery in San Diego.
