About DeVoss Codonanthe
Codonanthe devosiana · also called DeVoss Codonanthe, DeVos Codonanthe · houseplant
Codonanthe devosiana is a delicate trailing gesneriad from Brazil, producing small, glossy leaves and charming white tubular flowers with a yellow throat, followed by bright orange-red berries. It grows epiphytically in nature and adapts well to hanging baskets indoors, thriving in bright indirect light with consistently high humidity.
Preferred mix: Epiphytic or orchid-based mix
Watch for — Root rot from overwatering: The fine, epiphytic roots are highly susceptible to rot if kept in waterlogged or dense substrate. Use a very open mix and allow moderate drying between waterings. A pot with multiple drainage holes is essential.
Why devoss codonanthe needs this mix
DeVoss Codonanthe is an easy-going houseplant — it just wants a free-draining general mix that holds some moisture but never stays soggy.
- DeVoss Codonanthe 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.
For the full picture on what makes up a good mix, see our guide to the main types of soil and potting media — it explains why each ingredient above behaves the way it does.
What goes wrong with the wrong mix
The wrong soil is one of the most common reasons devoss codonanthe 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 devoss codonanthe'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 devoss codonanthe.
pH — does it matter for devoss codonanthe?
DeVoss Codonanthe 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 devoss codonanthe 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 devoss codonanthe needs — the free-draining mix does the rest.
Refresh devoss codonanthe'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 devoss codonanthe covers the timing and technique step by step.
