Hoya

Hoya carnosa

Vining & TrailingEasyModerate🐾 pet-safe
Good to know: The "wax plant" or "porcelain flower": clusters of star-shaped, sweetly-scented blooms that can drip sticky nectar. Nearly indestructible and pet-safe, a rare combo.

Through the year 🗓️

☀️ Summer now

Bloom season. Never cut the flower spurs; they rebloom from the same spot.

🍂 Fall

Taper the feed and let it dry harder between drinks.

❄️ Winter

A cool, dry rest now is the secret to summer flowers.

🌱 Spring

New vines run and feeding begins. Do not relocate a budding plant.

The details

Light & placement

Light
Bright indirect with some gentle direct sun; more light = more blooms
Ideal PPFD
200–450 µmol·m⁻²·s⁻¹
Grow-light distance
12–18 in below LED

Water & feed

Watering method
Soak-and-dry. Its thick, semi-succulent leaves store water, so let the mix dry most of the way between drinks.
Fertilizer
Balanced feed at ½ strength monthly while growing; a higher-phosphorus feed encourages blooming.

Home & habit

Soil
Very airy, chunky mix (orchid bark + perlite + coco); pH 6.1–7.5
Humidity
Average–high (40–60%)
Temperature
60–85 °F
Mature size
Trailing/climbing vines 2–6+ ft
Repotting
Rarely; blooms best when snug & root-bound
Propagation
Stem cuttings with 1–2 nodes in water, soil, or sphagnum. Very reliable.

When something looks wrong

Overwatering signs
Soft, yellowing, dropping leaves; mushy stems
Underwatering signs
Wrinkled, dimpled, softening leaves
Common pests
Mealybugs (love the leaf axils), aphids, scale
Care notes: Do NOT cut off the bare flower stalk (peduncle) after blooming. It reblooms from the same spur for years. Keep it a little pot-bound for flowers.

Common problems 🩺

The usual suspects when Hoya looks unhappy. Most houseplant trouble is watering or light, not disease — see all plant problems if you are not sure which plant is the culprit.

Never flowers

Likely cause
Not enough light, or the flower spurs were pruned off.

What to do
Give it bright light and never cut the little bare stubs — those are where blooms return each year.

Yellowing leaves

Likely cause
Overwatering — hoyas have thick semi-succulent leaves and store water.

What to do
Let the mix dry out most of the way, and use a chunky, airy potting mix.

Wrinkled, dimpled leaves

Likely cause
Thirst, or roots damaged by earlier overwatering.

What to do
Water thoroughly. If the leaves stay wrinkled in moist soil, check the roots.
