About Cryptocoryne wendtii 'Red'
Cryptocoryne wendtii 'Red' · also called red Wendt's Crypt, wendtii red · tropical
Cryptocoryne wendtii 'Red' is a reddish-bronze cultivar of the hardy Sri Lankan water trumpet, forming a compact 10-20 cm submerged rosette. Its colour deepens under brighter light and good nutrition, while it still tolerates low-tech tanks. A reliable, slow-but-steady midground plant prized for warm tones in planted freshwater aquariums.
Preferred mix: Nutrient-rich aquarium substrate
Watch for — Slow establishment: Newly planted Crypts often pause for weeks. Be patient and avoid moving them while roots anchor.
Why cryptocoryne wendtii 'red' needs this mix
Cryptocoryne wendtii 'Red' is an easy-going houseplant — it just wants a free-draining general mix that holds some moisture but never stays soggy.
- Cryptocoryne wendtii 'Red' 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 cryptocoryne wendtii 'red' 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 cryptocoryne wendtii 'red''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 cryptocoryne wendtii 'red'.
pH — does it matter for cryptocoryne wendtii 'red'?
Cryptocoryne wendtii 'Red' 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.
