About the Brazilian Raintree Bonsai Tree

The Brazilian rain tree is a deciduous tree native to the rainforests of Brazil. The rain tree has delicate branches and small pale green leaves and ridges. The leaves will be opened at night and re-opened in the morning.

Its grows fragrant fuzzy flowers.

The rainbow’s unique appearance makes it one of the most interesting rainforest bonsai.

This tree can withstand temperatures in the upper 30s, but not for long. Although growing in full sun in the wild, Brazilian Raintrees like bonsai seem to appreciate some shade during the hottest days of tropical summers.

This is a tree that can survive and thrive indoors as a potted plant all year round.


Brazilian Raintree can live indoors all year, but prefers to be outdoors as long as the temperature is above 45 degrees. It loves light, and should get plenty of it on a south- (or east- or west-facing) window sill while indoors – though it performs well in lower light conditions.


The Brazilian rain tree, like most bonsai trees, will die if it dries out. It has much water in well draining soil. Never allow it to dry completely.


The Brazilian rain tree loves humidity, but will be good in drier air.


Since your Brazilian Rain Tree bonsai is in a small pot and does not need the soil it needs nutrients. A slow release (pellet based) fertilizer is perfect for this and can be added sparingly every other month during the growing season.

Pruning and trimming

Cut back the new growth to the longest safe point that looks good to you – but never remove all the new growth.

A regular trim will help you keep your Brazilian rain tree bonsai tree short, while the trunk becomes thicker.


Repotting must be done regularly on your bonsai, Brazilian rain trees included, when its root system has filled the pot. If you can clearly see roots coming out of the bottom of the pot, it’s time to reposition your bonsai.

Generally, this means 2-3 years for a deciduous tree and 4-5 years for an evergreen. The Brazilian rain tree, which is tropical, will need to be repositioned every 2-4 years depending on its environment.

Staining should be done in the middle of summer, when the tree is in the least fragile state.

Your Brazilian rain tree bonsai, along with all its soil, should be removed from the pot. From there, you can trim away at most one-third of the root mass (1/4 preferred.)

Then you can reposition the tree in the same pot, or give it a newer / larger pot to thrive in.

After repotting, your bonsai Brazilian Rain Tree should be watered thoroughly.

Diseases, insects and other pests

Your Brazilian rain tree Bonsai can be treated for pests like a normal Brazilian rain tree. Just remember that your tree is miniature and will need a much smaller and more gentle dose of treatment.
