About Hoya Krimson Queen

Hoya carnosa 'Krimson Queen' · also called Krimson Queen wax plant, variegated wax plant · houseplant

The Hoya Krimson Queen is a variegated wax plant cultivar with creamy-white leaf margins and pink-flushed new growth, grown as a trailing or climbing vine. Give it bright indirect light, water only when the soil dries, and it stays easygoing. ASPCA lists Hoya carnosa as non-toxic to cats and dogs, making it pet-friendly.

Mature size: Vines reach roughly 4-6.5 ft (1.2-2 m) indoors with support or trailing; individual leaves about 2-3 in (5-7 cm) long.

Watch for — Overwatering and root rot: The most common killer. Yellowing, soft, or mushy leaves and black stems point to soggy soil. Let the mix dry out between waterings and ensure the pot drains freely.

How to tell hoya krimson queen needs repotting

Repotting on a calendar is less reliable than reading the plant. For hoya krimson queen, watch for these signs:

Roots growing out of the drainage holes, or the rootball lifting the plant proud of the rim.
Soil that has shrunk away from the pot sides and no longer holds water.
The pot is unstable because the plant has grown top-heavy.
Old, compacted, broken-down mix that stays wet too long — for a succulent that is a rot risk, so refresh it even if the pot size is fine.

The best time of year to repot hoya krimson queen

Spring or summer, while hoya krimson queen is in active growth and warm, is best — roots recover fastest then, and the plant is not sitting in cool damp soil. Avoid repotting a succulent in winter dormancy.

Step-by-step: repotting hoya krimson queen

Repot dry. Do not water hoya krimson queen for several days first. Working with dry roots and dry mix dramatically lowers the rot risk for a succulent.
Pick a snug, fast-draining pot. Choose terracotta one size up at most, with a drainage hole. Have gritty chunky, fast-draining aroid/epiphyte-style mix ready.
Tip it out and clean the roots. Slide the plant out, crumble off the old soil, and trim any black, mushy or dead roots with clean snips.
Pot into dry mix. Set hoya krimson queen at its original depth in dry gritty mix, firming gently. Do not bury the stem deeper than it was.
Wait a week before watering. Leave it completely dry and out of harsh sun for about 7 days so any damaged roots callus. Only then water lightly.

Aftercare

Keep hoya krimson queen completely dry and out of fierce sun for about a week so any nicked roots callus before they meet moisture; watering a freshly repotted succulent is the classic way to rot it. Then resume the normal lean, dry rhythm. Do not fertilise for about 3 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for hoya krimson queen

Hoya Krimson Queen wants chunky, fast-draining aroid/epiphyte-style mix. Use an airy, well-draining blend such as equal parts potting mix or peat/coir, orchid bark, and perlite or pumice. As an epiphyte it wants oxygen at the roots, so avoid dense, water-retentive soil. Always use a pot with drainage holes. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.
