About Anguloa clowesii

Anguloa clowesii · also called Cradle Orchid, Tulip Orchid · flowering

Anguloa clowesii, the cradle or tulip orchid, is a cool-growing Colombian species famous for cupped, waxy lemon-yellow spring flowers with a loose, rocking lip that gives it its name. Closely related to Lycaste, it forms large pseudobulbs and broad pleated deciduous leaves, and needs bright light, generous summer water, and a cooler winter rest to bloom.

Mature size: Pseudobulbs 10-15 cm tall with leaves arching to 45-75 cm; flower stalks 15-30 cm bearing solitary cupped blooms about 6-8 cm across.

Watch for — Root rot: Heavy water during the cool rest or broken-down mix holding water. Repot into fresh open bark and keep winter watering light.

How to tell anguloa clowesii needs repotting

Repotting on a calendar is less reliable than reading the plant. For anguloa clowesii, watch for these signs:

Roots spiralling thickly out of the drainage holes or pushing the whole plant up out of the pot.
The pot is so packed that water runs straight through in seconds and barely wets the soil.
It has split a plastic pot, or the rootball is a solid mass with almost no soil left when you slide it out.
Growth and (for anguloa clowesii) flowering have clearly stalled despite good light and feeding — but remember this plant likes being snug, so a little crowding alone is not a reason to 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 anguloa clowesii

Only every 2–4 years, when genuinely crowded. Anguloa clowesii is one of the plants that genuinely prefers a snug pot — it grows and flowers better with its roots a little restricted, so resist the urge to repot it on schedule. Sympodial, deciduous orchid forming large clustered pseudobulbs topped with broad pleated leaves. Several single-flowered stalks rise from the base of each new growth in spring, the cupped blooms rocking a hinged lip when touched..

What size pot to step anguloa clowesii up to

Go up only one pot size — roughly 2–3 cm (about an inch) wider in diameter, no more. Anguloa clowesii positively prefers a snug pot: it flowers and grows better when the roots are a little restricted. The single biggest repotting mistake here is over-potting — dropping anguloa clowesii into a pot two or three sizes up. All that surplus soil holds water the small root system cannot use, stays cold and wet, and rots the roots within weeks. When in doubt, choose the smaller pot.

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 anguloa clowesii

Early spring, just as new growth restarts, is the ideal window for anguloa clowesii. 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 anguloa clowesii

Confirm it actually needs it. Slide anguloa clowesii out and check the roots. Only continue if it is genuinely packed — this plant prefers a snug pot, so if there is still soil and room, put it straight back.
Pick a pot only one size up. Choose a pot just 2–3 cm wider with good drainage. Resist anything bigger; over-potting is the main killer here.
Ease it out gently. Water lightly the day before, then tip anguloa clowesii out, supporting the base. Tease the outer roots free only enough to stop them circling.
Repot at the same depth. Add a layer of fresh open medium-grade bark orchid mix, set the plant so the soil line sits exactly where it did before, and backfill around the sides, firming lightly.
Settle it in. Water once to settle the soil, then let it sit. Hold off on more water until the top of the soil dries — fresh soil around a small root system stays wet for a while.

Aftercare

Because the new soil holds more water than the old crammed rootball did, ease right back on watering — let the top of the soil dry before you water anguloa clowesii again, or you will rot the roots in the very pot you just moved it to. Keep it out of harsh direct sun for a fortnight. Do not fertilise for about 4 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for anguloa clowesii

Anguloa clowesii wants open medium-grade bark orchid mix. A buoyant bark mix with perlite and charcoal, often with a little added sphagnum for the thirsty root tips, in a pot that drains fast. Repot every couple of years as new growth begins, since these vigorous rooters dislike stale, decomposed media that suffocates the roots. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting anguloa clowesii — frequently asked questions

How often should you repot anguloa clowesii?

Only every 2–4 years, when genuinely crowded for anguloa clowesii. Only repot anguloa clowesii every 2–4 years, and only when it is genuinely root-bound — it flowers and grows best slightly crowded. Step up just one pot size in spring using open medium-grade bark orchid mix. The key mistake is over-potting: a too-big pot stays wet and rots the roots.

What size pot does anguloa clowesii need?

When is the best time of year to repot anguloa clowesii?

Does anguloa clowesii like to be root-bound?

Yes — anguloa clowesii genuinely flowers and grows best when slightly pot-bound, so do not rush to repot it. The mistake to avoid is over-potting into a much larger pot: the excess soil stays wet, the roots cannot use it, and the plant rots. Only repot every few years and only one snug size up.

Should you fertilise anguloa clowesii after repotting?

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