About Campbell's Lycaste
Lycaste campbellii · also called Campbell's Lycaste · tropical
Campbell's Lycaste is a compact Central American orchid prized for its delicate, fragrant flowers in soft yellow-green tones. Grow it in intermediate temperatures with bright indirect light, a distinct dry rest after leaves drop, and excellent drainage. Deciduous pseudobulbs shed leaves seasonally — this is normal, not disease.
Preferred mix: Fine-bark orchid mix with added perlite
Watch for — Pseudobulb shrivelling: Caused by either underwatering during growth or root rot reducing uptake. Check roots — healthy roots are white/green; brown mushy roots indicate rot. Trim rot, repot into fresh dry mix, and resume careful watering.
Why campbell's lycaste needs this mix
Campbell's Lycaste is an easy-going houseplant — it just wants a free-draining general mix that holds some moisture but never stays soggy.
- Campbell's Lycaste is adaptable, but like most houseplants it still needs air at the roots — a mix that drains freely while holding a working moisture reserve.
- A little perlite or bark stops ordinary compost compacting into an airless block over time, which is the slow, common cause of decline.
- It is not fussy about pH or special ingredients; getting the air-to-moisture balance right is what matters.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons campbell's lycaste struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- Plain garden soil or a cheap, claggy compost compacts in the pot and slowly suffocates campbell's lycaste's roots.
- A pure peat mix that dries to a hard, water-repelling block is hard to re-wet and stresses the plant.
- No drainage hole turns even a good mix into a stagnant, root-rotting sump.
Reusing tired, compacted old compost or skipping the perlite. A free-draining mix in a pot with a hole solves most "why is it struggling" cases for campbell's lycaste.
pH — does it matter for campbell's lycaste?
Campbell's Lycaste is not fussy about pH — a slightly acidic to neutral mix (around pH 6.0-7.0), which a standard peat-free compost provides, is perfectly fine. No testing needed.
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 decent bagged houseplant compost works for campbell's lycaste as long as you mix in perlite for air. The simple DIY ratio above is cheap and more reliable than a budget bag alone.
Drainage and the pot
A pot with a drainage hole and a saucer you empty after watering is all campbell's lycaste needs — the free-draining mix does the rest.
Refresh campbell's lycaste's mix every 18-24 months; even good compost slumps and compacts, and fresh, airy mix is often the simplest fix for a tired plant. When the time comes, our repotting guide for campbell's lycaste covers the timing and technique step by step.
