Hoya carnosa ‘Chelsea’

Origin of Hoya carnosa ‘Chelsea’

‘Chelsea’ was in horticultural use by around 2008. Its originator remains uncertain.

Growing Hoya carnosa ‘Chelsea’ at home

‘Chelsea’ can trail or grow on a hoop or trellis. Give it bright indirect light, sheltered from hot sun, at about 16–24 °C and 50–60% relative humidity. Keep it above about 10 °C, with air moving gently around the cupped foliage.

Use chunky potting mix in a container with drainage holes. Water when the pot feels light and the mix is nearly dry throughout; check moisture deeper in the mix before soaking and draining the roots. Lower light, cooler conditions and slower growth mean longer drying times.

Use balanced orchid fertiliser about every two weeks while new growth develops, at a modest dose. When roots fill the pot, move the plant into the next pot size. If the mix degrades while the roots still fit the pot, refresh it in the same-sized container.

Take a healthy one- or two-node stem cutting and root it in an airy propagation medium. Keep it warm in bright indirect light until roots form.

Common issues with Hoya carnosa ‘Chelsea’

• Cupped leaves become soft or start to shrivel: ‘Chelsea’ naturally has cupped, dimpled leaves that feel firm when healthy. Check whether the mix around the roots is dry. If the root ball is dry, water thoroughly and drain. If the leaves still wilt after watering, inspect the roots. Avoid repeated watering while the roots are still wet.
• Wilting while the mix remains wet: Persistent wetness can damage roots. Drain trapped water and inspect roots if decline continues. If you find a small amount of root rot, use a clean, disinfected tool to cut the soft roots back to firm, healthy tissue. Throw away the rotten roots and old mix. Repot in fresh, airy mix, using a clean pot just large enough for the roots that remain. The pot must have drainage holes. If decay is widespread, save only healthy stem cuttings. Discard the plant if no healthy stems remain, and disinfect your tools afterwards.
• Cottony insects around leaf bases: Confirm mealybugs beneath the wax and isolate the plant. Remove visible insects with a damp swab or tweezers. Inspect sheltered leaf joints, stems, the pot and any support weekly, removing any mealybugs you find until none remain. If mealybugs persist, use a product approved for home use against mealybugs on indoor ornamental plants in your country. Follow the label for how much to use, where to apply it, when to repeat treatment and all safety precautions.
