Cryptocoryne wendtii requires a moderate amount of maintenance and is considered to be a steady grower once it's established, but it does not like to be moved. This species also requires a stable environment or the stems and leaves will start to rot and eventually, the entire plant will "melt". Cryptocoryne wendtii may be planted as solitary or grouped plants.
Cryptocoryne wendtii will thrive in an iron-rich substrate and will benefit from regular additions of CO2, high-quality iron-rich fertilizers, and trace elements. Cryptocoryne wendtii requires a low to moderate level of light at 2 to 3 watts per gallon with full spectrum (5000-7000K) bulbs.
Established Cryptocoryne wendtii plants will send out runners that will develop into dense communities after several weeks. Occasional trimming of the runners is recommended using a sterile razor blade or very sharp, sterilized scissors. For propagation, allow the new plant to form its own leaves prior to separating it from the mother plant.
