How to propagate Hoya Pubicalyx

Water (stem cuttings)

Difficulty: EasyTimeline: Roots in 3-6 weeks; pot up once roots reach 1-2 inches.
  1. Cut a vine section with at least 2 nodes and one or two leaves.
  2. Remove the lowest leaf so a bare node sits below the waterline.
  3. Place in a jar of water in bright, indirect light.
  4. Change the water weekly; roots emerge from the nodes.
  5. Pot into a chunky, bark-rich mix once rooted.

Soil (stem cuttings)

Difficulty: EasyTimeline: Roots in 4-8 weeks.
  1. Take a cutting with 2+ nodes and let the cut end callus for an hour.
  2. Dip in rooting hormone (optional) and insert a node into moist, airy mix.
  3. Cover loosely to hold humidity and keep warm.
  4. Keep the mix barely moist until new leaves appear.

Common Hoya Pubicalyx problems & fixes

Yellow leaves

Usually overwatering. Let the soil dry more between waterings and confirm the pot drains well.

Brown, crispy leaf tips

Low humidity or salt buildup. Raise humidity and flush the soil with plain water occasionally.

Leggy growth / small new leaves

Too little light. Move to brighter indirect light and prune to encourage fuller growth.
