Euphorbia balsamifera

Euphorbia balsamifera

Cultivation and propagation: It is an easy to grow plant. It grows well in a very draining mineral potting substrate, but it isn't picky about soil. Outdoors it requires a deep sandy soil. It slowly grows into a large, many stemmed specimen.
Water requirements: It can be watered moderately from autumn to spring (except in the coldest month of the winter, as it rots easily, especially if over-wet). During the summer, they lose their leaves and enter in a rest phase. In this period diminish waterings to one at a month.
Hardiness: In winter, keep it dry above 4°C. Mature healthy plants are tough and can also be grown outside in frost free areas, but when left out it is more sensitive to frost.
Exposure: They do need a lot of light to keep their compact growth-form, but different clones vary in their tolerance of full sunshine. The plants that are not kept in full sun grow faster but became untidy and may need support as they get larger, or branches will fall off. Sometimes, in really hot full sun all day long, a plant will bleach out a bit.
