Frequently Asked Questions

Why is my Hoya Australis not flowering even though it's growing well?

Hoyas typically need to mature and become somewhat root-bound before they bloom. Healthy vine growth without flowers usually just means it needs more time, plus bright indirect light to trigger blooming.

Should I cut off the dried flower stalks (peduncles) after my Hoya Australis blooms?

No — leave them in place, since Hoya peduncles often produce new flower clusters again from the same spot in future seasons. Cutting them off removes future bloom sites.
