How to Grow Guava Indoors

Guava is a pulpy, sweet, and juicy fruit that thrives mainly in tropical regions. This cold-sensitive plant is an ideal container tree as it does well indoors in easily achievable conditions. Guava fruit is eaten raw or used as an ingredient in drinks, desserts, jams, and candies. In many parts of the world, the fruit is eaten with a little sprinkling of salt which brings out its sweet and mellow flavor.


Guava trees can be grown in containers and can be kept as small as 4 feet tall, making it an ideal indoor container tree. An indoor guava tree is best planted in a pot the same size or 2 inches larger than the nursery pot. A pot that has at least one drainage hole in the bottom allows excess water to drain out. To keep it the same size, you can prune off up to one-third of the roots and re-pot it in the same pot with fresh potting soil.

Lots of light and soil with ample drainage keep guava trees happy in an indoor environment. A spot that gets full sun, at least six hours per day of either direct sun or filtered bright light is ideal. Keep them indoors all year or outdoors in spring, summer and fall. A winter temperature range of 55 to 60 degrees Fahrenheit is ideal; at temperatures cooler than 50 F the tree starts to lose leaves.

Indoor guava trees benefit from deep watering followed by a period of drying out. In general, when the top three of four inches of the soil feels dry, it’s time to soak the pot again. Fertilizers vary, so always follow the instructions on the package label to determine how much to use and how much to apply. Young guava are vulnerable to pests including aphids, mealy bugs, scale, and white fly. If possible, identify the infestation as early as possible and treat with the leave toxic option.
