About Hoya Pubicalyx 'Silver Pink'

Hoya pubicalyx 'Silver Pink' · also called Silver Pink hoya, splashed hoya · houseplant

Hoya pubicalyx 'Silver Pink' is a fast, forgiving Philippine wax vine with long, dark leaves splashed silvery-pink and umbels of dusky pink-to-near-black fragrant flowers. One of the easiest hoyas for beginners, it grows quickly on bright indirect light, tolerates average household humidity and blooms readily once mature in a chunky, free-draining mix.

Mature size: Vines readily reach 3-4 m indoors; easily trained or pruned to 1-1.5 m, and one of the quicker hoyas to fill out.

Watch for — Faded leaf splashing: Insufficient light dulls the silvery flecks. Move to a brighter spot to restore the speckled, sometimes pink-flushed colouring.

How to tell hoya pubicalyx 'silver pink' needs repotting

Repotting on a calendar is less reliable than reading the plant. For hoya pubicalyx 'silver pink', watch for these signs:

Thick roots out of the drainage holes, or circling the surface and lifting the plant.
The pot dries out unusually fast and hoya pubicalyx 'silver pink' wilts between waterings it used to shrug off.
The plant is visibly top-heavy and tips over easily.
Stalled growth and small new leaves over a full season — though with a big specimen, top-dressing is often the better first response before a full repot.

For the underlying biology of a pot-bound root system and why it stalls a plant, see our guide to spotting and fixing a root-bound plant.

How often to repot hoya pubicalyx 'silver pink'

Every 2–3 years; top-dress in the in-between years. Hoya Pubicalyx 'Silver Pink''s growth habit — vigorous, fast-growing twining epiphytic climber. long stems trail attractively from a hanging basket or climb a trellis quickly, and it flowers prolifically from persistent woody spurs once established. — sets the pace. Hoya pubicalyx 'Silver Pink' is a fast, forgiving Philippine wax vine with long, dark leaves splashed silvery-pink and umbels of dusky pink-to-near-black fragrant flowers. One of the easiest hoyas for beginners, it grows quickly on bright indirect light, tolerates average household humidity and blooms readily once mature in a chunky, free-draining mix.

What size pot to step hoya pubicalyx 'silver pink' up to

Move up exactly one pot size. A heavy hoya pubicalyx 'silver pink' dropped into a vastly bigger pot sits in a reservoir of wet soil its roots cannot reach, which rots them and destabilises the plant. In the years between repots, lift off and replace the top 3–5 cm of soil (top-dressing) instead — it refreshes nutrients without the shock of a full repot.

Not sure of the exact diameter? Our pot size calculator takes the current pot and root spread and tells you the right next size — it deliberately recommends a single step up, never a big jump.

The best time of year to repot hoya pubicalyx 'silver pink'

Early spring, just as new growth restarts, is the ideal window for hoya pubicalyx 'silver pink'. The plant is moving into its strongest growth phase and re-roots into fresh soil quickly. Avoid repotting in winter dormancy or, for flowering plants, while it is in bud or bloom — recovery is slowest then and you risk dropping the flowers.

Step-by-step: repotting hoya pubicalyx 'silver pink'

Consider top-dressing first. If hoya pubicalyx 'silver pink' is not badly root-bound, scrape off and replace the top 3–5 cm of soil instead — far less shock for a big plant that hates moving.
Get help and one size up. For a full repot, choose a pot just one size larger. A heavy plant needs two people and a stable, free-draining pot.
Ease it out on its side. Lay the plant down, slide the pot off, and gently loosen the outer roots. Do not bare-root a mature specimen.
Repot at the same depth. Add fresh chunky, fast-draining epiphytic mix beneath and around the rootball, keeping the original soil line. Firm it so the trunk is stable and upright.
Water and leave it put. Water thoroughly, then leave hoya pubicalyx 'silver pink' in the same spot and light — moving and repotting at once is what makes it drop leaves.

Aftercare

Leave hoya pubicalyx 'silver pink' in exactly the same spot and light it was in before — moving and repotting at the same time is what makes a big specimen drop leaves. Water it in well, then let the top of the soil dry before watering again so the larger volume of fresh soil does not stay sodden. Do not fertilise for about 4 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for hoya pubicalyx 'silver pink'

Hoya Pubicalyx 'Silver Pink' wants chunky, fast-draining epiphytic mix. Orchid bark, perlite and a little coco coir or peat (about 2:1:1) provide the airflow these roots like. Horticultural charcoal helps keep the medium fresh. It is tolerant of mix type provided drainage is excellent. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting hoya pubicalyx 'silver pink' — frequently asked questions

How often should you repot hoya pubicalyx 'silver pink'?

Every 2–3 years; top-dress in the in-between years for hoya pubicalyx 'silver pink'. Fully repot hoya pubicalyx 'silver pink' only every 2–3 years; in the in-between years just top-dress the top 3–5 cm of soil. Step up one pot size in spring with chunky, fast-draining epiphytic mix. It is heavy and hates being moved, and a vastly oversized pot holds water against the roots and rots them.

What size pot does hoya pubicalyx 'silver pink' need?

When is the best time of year to repot hoya pubicalyx 'silver pink'?

Should you top-dress or fully repot hoya pubicalyx 'silver pink'?

For a big, heavy hoya pubicalyx 'silver pink', top-dressing — replacing the top 3–5 cm of soil — is the gentler option most years, with a full repot only every 2–3 years. A mature specimen sulks and drops leaves when fully repotted, so do it as rarely as the roots allow.

Should you fertilise hoya pubicalyx 'silver pink' after repotting?

Not immediately. Wait about 4 weeks after repotting hoya pubicalyx 'silver pink'. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
