CARE GUIDE

How to keep Eriostemon Australasius.

Light

pink wax flower naturally occurs in habitats like forest understories or rocky areas, where it grows in natural shade. It prefers partial sun but can tolerate full sun or full shade, showing its versatility and hardiness.

Temperature

The pink wax flower is very adaptable to a variety of climates, from blazing summers to cold winters. That said, it does have a preferred temperature range for healthy growth. If temperatures climb too high, the plant can experience heat and humidity stress that may kill it. In areas where temperatures near the lower bound of its cold tolerance, it’s important to provide insulation to protect the plant.

Fertilizer

Timing matters when fertilizing the pink wax flower. Begin in early spring and apply fertilizer monthly through early summer. Fertilizer promotes attractive blooms and supplies energy during both dormancy and periods of active growth.

Pruning

Eriostemon australasius is known for its fragrant leaves and star-shaped flowers. To keep the plant healthy and promote fuller growth with more blooms, prune it in early spring. Start by removing any dead branches, then lightly trim any overgrown shoots, being careful not to cut into the old wood. Make sure to use clean, sharp tools to minimize the risk of spreading disease.
