Can mango trees grow indoors?

Growing dwarf mango trees indoors does take juggling light in addition to moisture and space. I have been growing six potted mangoes (specifically the varieties, Cogshall and Irwin) in my sunroom with the best success. Their ability to reach less than 6ft in height makes trimming for ceiling height easy while producing 20-30 fruits a year with LED grow lights.

Hand-pollination will ensure that your indoor plants set fruit. Every morning, for a week straight, use a soft brush to move pollen among your flowers. My first attempt was ultimately a failure and only led me to this conclusion after timing it with the full opening of the flower, which I found was from 10 AM - probably yielding a lot of pollen that was viable.

Make strategic use of dormancy to prune the plant. Consider selectively removing vertical shoots to promote an increase in horizontal branching. I shape trees into an open-center vase so that light can penetrate more effectively. Root-prune trees every 2 years in 24-inch pots, this will encourage more feeder roots without impacting tree height growth.

Fertilize 6-6-6 lower NPK ratio every three months. Too much food and your trees grow more leaves than fruit. For example, one of my clients with an over-fertilized Irwin mango tree grew 18 lbs of leaves, but zero mangoes! Also, flush out the soil once a month to remove salt build-up. Yellow leaf tips often indicate excess nutrients in the soil.
