Over The Crassula Tree is an evergreen succulent native to South Africa where it can reach heights of 2 metres or more. In temperate zones Crassulas are regarded as indoor trees and should not be subjected to temperatures below 5-7 degrees centigrade (41-45 F). The Crassula has a thick trunk and branch structure with thick elliptic green succulent leaves. Given sufficient light, the leaves develop red edges to their leaves and produce clusters of star-shaped white flowers in Autumn. Natural leaf size is 1-2″ but can be reduced to as little as 1/2″ with regular pruning. The Crassula Tree is suitable for informal upright and clump styles in all sizes.
Specific Bonsai care guidelines for the Crassula
Position: The Crassula tree is considered an indoor tree in most temperate zones, although it can be grown outdoors in full sun (and sufficiently high temperatures). Keep temperatures above 5 degrees C (or 41F) at all times. It needs lots of light or even full sun.
Watering: Crassula trees can hold large amounts of water inside their leaves. Water sparsely and allow the plant to dry out a little bit between watering. During winter time, watering can be as seldom as once every three weeks. The Crassula is not as particular about over-watering as most other succulents.
Feeding: Once a month during the growth season (spring-autumn).
Pruning: Pruning: New growth should be continually pinched out to encourage stronger lower growth and to reduce leaf-size. Crassulas readily make new growth from wounds and individual leaves can be removed to quickly produce new branches.
Never seal pruning wounds; wound sealants can trap moisture within the wound site and cause rotting. Leave pruning wounds open and allow to dry naturally.
Crassulas respond very well to trunk reduction techniques, producing new growth from the wound area within 1-2 weeks.As a succulent, water is contained its trunk and branches; they tend to bend from their weight. Crassulas respond well to pruning, which should be done regularly to force the tree to grow branches also lower on its trunk. Do not use cut-paste though, as this might lead to rotting.
Repotting: Repot the three every second year in spring, using a very well-draining soil mixture.
