FEATURES

The Hawaiian Umbrella Tree boasts glossy, finely divided leaves and displays striking umbels that yield orange-red to black berries. The leaves are shaped like tiny umbrellas and form a dense, verdant canopy. The trunk is slender and does not branch out, making for an interesting and eye-catching root growth. A dwarf variety of this tree is also available and makes a stunning bonsai.

TEMPATURE

The Dwarf Hawaiian Umbrella Tree is a subtropical species that prefers temperatures ranging from 64 to 71 degrees. As it has a fondness for warmth, it can be positioned near a heat source, but should never be exposed to temperatures lower than 59 degrees. If you want to take it outside during warm weather, it should be acclimated gradually to prevent leaf damage from sunburn. However, once the temperatures start to drop in the fall, it is important to bring the plant indoors to maintain a warm environment.

LIGHTING

It is recommended to keep the Dwarf Hawaiian Umbrella Tree indoors near a bright window. The brighter the light the plant receives, the smaller its leaves will be and the more compact its stalk will become, resulting in a more desired appearance for a Bonsai. If the lighting is not adequate, the stalks may become elongated and will not have the desired aesthetic for Bonsai styling.

WATERING

For optimal root health, it is important to water the Dwarf Hawaiian Umbrella Tree sparingly and only when the soil is starting to dry out. This helps to promote short internodes and small leaves. When watering, ensure that the water runs through the drainage holes in the container to prevent salt buildup. A humidity tray can be useful in increasing the humidity levels, which can encourage the growth of aerial roots. The tray is filled with small stones and holds water at the bottom, but it is important to make sure the water level does not reach the bottom of the Bonsai pot to avoid root rot. As the water evaporates, it will create a suitable level of humidity that mimics the plant’s natural habitat.

PRUNNING

To shape the Dwarf Hawaiian Umbrella Tree, it is recommended to remove the tips of new shoots when they reach the desired length. Large leaves can also be trimmed, but it is best to leave the leaf stalks, as they will eventually fall off on their own. If the humidity levels are high enough, older trees may develop aerial roots, adding to its exotic appearance. While the shoots are still relatively green, wiring is possible, but care must be taken to avoid damaging the bark. This plant may not be suitable for training into traditional Japanese Bonsai forms, but it can be shaped into informal uprights or multiple trunk or forest group styles.

PROPAGATION

The Umbrella Tree can be propagated using seeds, which is the preferred method. To do so, mix bonsai soil, loam, peat moss, and sand in equal parts, and sow the seeds immediately after acquiring them. Maintain a temperature of around 68 to 86 degrees, and cover the seeds with soil or sand. The seeds of this plant germinate quickly.

REPOTTING

It is recommended to repot and prune the roots of the Umbrella Tree every two years during the spring, taking care to remove all large leaves.
