Houseplant clinic: why won’t my wax plant bloom?

Strangely, this plant benefits from mild stress and ‘benign neglect’. So limit the nutrients and watch it flower!

What’s the problem?
My Hoya carnosa cutting, taken from my father’s treasured plant, bloomed once, in 2022, but has not flowered since. How can I encourage it?

Diagnosis
Hoyas, often known as wax plants, have a reputation for thriving on “benign neglect”. They flower best when slightly stressed, as this triggers their reproductive mode. Regular watering and abundant nutrients will encourage leaf growth rather than blooms.
