Planting and Caring for Your Calamansi Tree

Once you have selected the right calamansi variety, it’s time to start planting. Follow these steps to ensure your calamansi tree thrives:

1. Choose a sunny location: Calamansi trees require at least six hours of direct sunlight daily. Pick a spot in your garden that receives ample sunlight to promote optimal growth.

2. Prepare the soil: Calamansi trees prefer well-draining soil with a pH level between 5.5 and 6.5. If your soil is heavy or clay-like, amend it with compost or sand to improve drainage.

3. Planting the tree: Dig a hole slightly larger than the root ball of your calamansi tree. Place the tree in the hole, making sure the soil line aligns with the top of the root ball. Fill the hole with soil, gently firming it around the tree.

4. Watering: Calamansi trees require regular watering, especially during the first few months of growth. Ensure that the soil remains consistently moist but not waterlogged. Reduce watering during the winter months.

5. Fertilizing: Apply a balanced citrus fertilizer every three months during the growing season. Follow the instructions on the fertilizer package for proper application rates. Avoid fertilizing during the winter months.

6. Pruning: Prune your calamansi tree regularly to maintain its shape and promote airflow. Remove any dead, damaged, or overcrowded branches. Pruning also encourages new growth and improves fruit production.

7. Pest and disease control: Keep an eye out for common pests such as aphids, mites, or scale insects. Regularly inspect your tree for signs of infestation and take appropriate measures, such as introducing natural predators or using organic insecticides. Monitor for diseases like citrus canker or citrus greening and take prompt action if identified.

Harvesting Calamansi

Patience is key when growing calamansi, as it takes approximately nine to twelve months for the fruit to ripen. Once the calamansi turns a vibrant orange color, it’s time for harvest. Follow these tips to ensure a successful harvest:

– Gently twist the fruit off its stalk. Avoid pulling or yanking, as this can damage the branch or affect the growth of new fruit.
– Calamansi fruit can be stored at room temperature for about a week. If stored in the refrigerator, they can last up to two weeks.
– To extract the juice, roll the calamansi between your palms to soften it. Cut the fruit in half and squeeze the juice into a container. The juice is commonly used in beverages, marinades, dressings, or as a flavor enhancer.


Growing calamansi can be a rewarding experience. By selecting the right variety, providing adequate care, and being patient during the ripening stage, you can enjoy an abundant supply of this tangy and versatile fruit. Whether you have a spacious garden or a cozy balcony, growing calamansi is an excellent way to add a touch of freshness to your culinary creations.
