Frequently Asked Questions

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

No — the same peduncle often reblooms in following seasons, so removing it means losing a future flower cluster. Just leave the spent stalk in place.

Why is my Hoya Carnosa not producing its signature waxy flower clusters?

Flowering usually requires a mature, somewhat root-bound plant with strong indirect light. Young or recently repotted plants often need more time before they're ready to bloom.
