Wax Plant Care at a Glance
Wax plants (Hoyas) are prized for their waxy leaves and stunning, fragrant blooms that appear on mature plants.
Best For
- Bright indoor spaces
- Hanging baskets
- Patient plant owners
- Flowering plant lovers
Not Great For
- Low light rooms
- Overwatering habits
- Cold environments
Light Requirements
Bright indirect light is the key to flowering. East- or west-facing windows are ideal. Too little light results in healthy leaves but no blooms.
How to Water a Wax Plant
Let the soil partially dry between waterings. Hoyas tolerate drought better than excess moisture.
Watering Tips
- Always use pots with drainage holes.
- Reduce watering significantly in winter.
- Thicker leaves = less frequent watering.
Flowering Tips
Do not cut old flower spurs (peduncles). Hoyas rebloom from the same spurs year after year.
Growth Habit
Wax plants are slow growers at first but can live for decades. Vines can be trained to trail or climb.
How to Propagate Wax Plant
- Cut a healthy vine with at least two nodes.
- Remove the lower leaves.
- Place cutting in water or airy soil mix.
- Roots typically develop within 2–4 weeks.
