Place the Ming tree bonsai in a humidity tray to help it retain water. Ming trees shouldn't be overwatered, but do like to stay moist.
Feed the Ming tree bonsai weekly with plant food that is diluted to half strength with water.
Test the Ming tree's soil pH. They flourish in pH levels between 6.5 and 7.5. Increase or decrease the soil pH as necessary.
Pinch back new growth to prevent branching, if it isn't in your desired design.
Prune and groom Ming tree bonsai foliage frequently. Branches grow upwards and can become bushy without trimming, and trimming is the best way to train the soft, fleshy branches.
