About Wendland's Bulbophyllum

Bulbophyllum wendlandianum · also called Wendland's Bulbophyllum, Cirrhopetalum wendlandianum · tropical

A miniature to small epiphyte or lithophyte from the forests of northern Myanmar and Thailand, Wendland's Bulbophyllum spreads along a creeping rhizome bearing spaced pseudobulbs, each tipped with a single leathery leaf. In spring it produces clusters of up to seven fragrant flowers with striking red-and-yellow fused lateral sepals. It grows best on a slab or in a wide shallow basket with consistent moisture.

Mature size: Plant height to 10 cm; pseudobulbs ovoid, to 2 cm; individual flowers to 15 cm long with elongated lateral sepals

Watch for — Root desiccation on mounts: Mounted plants dry out very quickly, especially in heated indoor environments. Check moisture daily and mist or dunk the mount as needed. If the roots are shrivelling, increase watering frequency or attach more sphagnum moss to the mount.

How to tell wendland's bulbophyllum needs repotting

Repotting on a calendar is less reliable than reading the plant. For wendland's bulbophyllum, watch for these signs:

Roots poking out of the drainage holes or coiling visibly around the inside of the pot.
You are watering far more often than you used to because the rootball dries out within a day or two.
Water runs straight through and out the bottom without soaking in.
Top growth has slowed or new wendland's bulbophyllum leaves are noticeably smaller than older ones despite good light.

How often to repot wendland's bulbophyllum

Every 12–18 months — sooner if roots show fast. Wendland's Bulbophyllum's growth habit — creeping, branching sympodial epiphyte or lithophyte. the rhizome spreads horizontally with pseudobulbs spaced approximately 4 cm apart, each bearing a single stiff, lanceolate leaf. slowly forms an extensive mat. — sets the pace.

What size pot to step wendland's bulbophyllum up to

Step up one pot size — about 2–3 cm (an inch) wider. Wendland's Bulbophyllum grows fast, so it will fill that space within a season, but jumping several sizes at once still backfires: the unused soil stays soggy and rots even a vigorous root system. One size at a time, every year or so, is the rhythm.

The best time of year to repot wendland's bulbophyllum

Early spring, just as new growth restarts, is the ideal window for wendland's bulbophyllum. 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 wendland's bulbophyllum

Time it for spring. Repot wendland's bulbophyllum in early spring as growth restarts so it re-roots quickly into the fresh soil.
Choose one size up. Pick a pot about 2–3 cm wider with drainage holes. One step only — a much bigger pot stays soggy and rots roots.
Ease the plant out. Water lightly the day before, then tip wendland's bulbophyllum out and gently loosen any roots circling the bottom of the rootball.
Repot at the same depth. Put a layer of fresh cork bark or tree-fern slab; or shallow basket with open bark mix in the new pot, set the plant so its soil line is unchanged, and backfill, firming lightly.
Water and pause feeding. Water once to settle the soil. Hold off fertiliser for about a month — fresh mix already has nutrients and feeding now burns new roots.

Aftercare

Water wendland's bulbophyllum once to settle the soil, then let the surface dry before watering again — fresh mix around the roots stays wetter than the old compacted ball, so the commonest post-repot mistake is overwatering. Keep it out of direct sun for a week or two while roots re-establish. Do not fertilise for about 4 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for wendland's bulbophyllum

Wendland's Bulbophyllum wants cork bark or tree-fern slab; or shallow basket with open bark mix. Best mounted on cork bark, tree-fern fibre slabs, or driftwood with a thin layer of live sphagnum underneath the roots. If potted, use a very open bark-and-perlite mix in a wide, shallow basket to accommodate the creeping rhizome. Do not overpot. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting wendland's bulbophyllum — frequently asked questions

How often should you repot wendland's bulbophyllum?

Every 12–18 months — sooner if roots show fast for wendland's bulbophyllum. Repot wendland's bulbophyllum roughly every 12–18 months, in early spring as growth restarts. It grows fast and circles its pot quickly, so step up one size (about 2–3 cm wider) into fresh cork bark or tree-fern slab; or shallow basket with open bark mix. Don't jump several sizes — that soggy excess soil is what rots vigorous roots.

What size pot does wendland's bulbophyllum need?

When is the best time of year to repot wendland's bulbophyllum?

Can you put wendland's bulbophyllum straight into a much bigger pot?

No. Even a fast-growing wendland's bulbophyllum should only go up one pot size at a time. A vastly oversized pot holds a reservoir of wet soil the roots cannot reach, which stays cold and soggy and rots the roots — the opposite of what you wanted.

Should you fertilise wendland's bulbophyllum after repotting?

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