Calamansi, also known as calamondin, Philippine lime, or Philippine lemon, is an economically important citrus hybrid predominantly cultivated in the Philippines. It is native to the Philippines, Borneo, and Sulawesi in Indonesia in Southeast Asia, as well as southern China and Taiwan in East Asia.

Calamansi is one of those ingredients that makes Filipino and Malaysian dishes taste truly authentic. It tastes like a sour orange or a slightly sweeter lime, and it has a fragrance to match.

Caring for an indoor Citrofortunella microcarpa, commonly known as a Calamondin or Miniature Orange tree, requires a few important considerations. First, it needs a bright location near a window where it can receive at least six hours of sunlight daily. Ensure the plant is potted in well-draining soil and water it when the top inch of soil feels dry, being careful not to overwater as it can lead to root rot. Fertilize the tree regularly during the growing season with a citrus-specific fertilizer to provide essential nutrients. Pruning can be done to maintain a desired shape and remove dead or damaged branches. To encourage fruit production, the tree benefits from a period of cooler temperatures and reduced watering during the winter months. By following these care guidelines, your indoor Citrofortunella microcarpa can thrive and reward you with its vibrant foliage and delicious miniature oranges.
