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.

Preferred mix: Open medium-grade bark orchid mix

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.

Why anguloa clowesii needs this mix

Anguloa clowesii flowers hardest in a rich but free-draining loam — fed enough to fuel the display, open enough that the roots never waterlog.

What goes wrong with the wrong mix

The wrong soil is one of the most common reasons anguloa clowesii struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:

Either starving anguloa clowesii in a thin mix or drowning it in a heavy, badly drained one. It wants the rich-but-free-draining middle, plus a flowering (higher-potassium) feed in season.

pH — does it matter for anguloa clowesii?

Most flowering plants, including anguloa clowesii, do well around pH 6.0-7.0. A cheap soil test is worth it outdoors; one notable exception is any acid-lover (such as some hydrangeas), where pH directly changes flower colour.

If you want to check or adjust it, the soil pH guide walks through testing and the safe ways to nudge a mix more acidic or more alkaline.

DIY mix vs a bagged one

A quality bagged compost works for anguloa clowesii in pots if you add grit and a flowering feed. In beds, improving the existing soil with compost and ensuring drainage beats any bag.

Drainage and the pot

Free drainage protects the roots and especially the crown over winter — raised beds, grit in the planting hole and never a waterlogged spot. Containers must have a clear drainage hole.

For perennials, refresh the top layer and feed each spring rather than disturbing the roots; for container displays, start with fresh rich mix each season. When the time comes, our repotting guide for anguloa clowesii covers the timing and technique step by step.

3 parts good loam or quality peat-free compost : 1 part well-rotted compost or leaf mould : 1 part grit or perlite. Flowering is expensive for anguloa clowesii: producing buds, blooms and seed draws heavily on nutrients and steady moisture, so the soil has to keep delivering all season.

Can I use normal potting soil for anguloa clowesii?

A thin, hungry or sandy mix gives anguloa clowesii weak growth and few, short-lived flowers — it simply runs out of fuel.
