About Bogota kohleria
Kohleria bogotensis · also called Bogota kohleria, Tree gloxinia · houseplant
A velvety, rhizomatous gesneriad from the humid montane forests surrounding Bogotá, Colombia, grown for its pendant tubular flowers with a carmine-red outer tube and cream lobes heavily spotted with burgundy. It thrives in bright indirect light, moderate-to-high humidity, and a well-draining mix kept evenly moist in summer. The rhizomes allow a winter rest.
Preferred mix: Light, well-draining peat or coir-based gesneriad mix
Watch for — Botrytis (grey mould) on foliage: Water trapped in the dense leaf hairs creates ideal conditions for Botrytis cinerea. Always water at soil level, ensure good air circulation, and remove any dead or damaged leaves promptly.
Why bogota kohleria needs this mix
Bogota kohleria is an easy-going houseplant — it just wants a free-draining general mix that holds some moisture but never stays soggy.
- Bogota kohleria 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 bogota kohleria 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 bogota kohleria'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 bogota kohleria.
pH — does it matter for bogota kohleria?
Bogota kohleria 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 bogota kohleria 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 bogota kohleria needs — the free-draining mix does the rest.
Refresh bogota kohleria'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 bogota kohleria covers the timing and technique step by step.
