Cryptocoryne wendtii is an extraordinarily hardy plant, and it will thrive under low lighting and in both soft and hard water conditions. It is an excellent plants for both experienced and beginner aquarists, as while it is easy to grow, it can also be aquascaped into stunning displays in experienced hands.

Cryptocryne wendtii will flourish under low light conditions. Due to its slow growing nature, other plants may crowd it out in aquariums with high levels of lighting. When choosing lighting, a T5 or T8 fluorescent bulb should be used to mimic full spectrum lighting. Some aquarists have reported success with LED lights in recent years, so these lights may also make a good choice for growing cryptocoryne wendtii.
When first introducing cryptocoryne wendtii to an aquarium, it is common to experience a significant leaf die off. Many of the leaves will quickly wither away, but don’t assume that the plant is dead if this happens. This is common occurrence, and is a result of a sudden change to the plants water conditions. The roots of the plant will normally remain healthy, and new leaves should been seen shortly (though this can sometimes take a while).
Propagation
Propagation is simple for cryptocoryne wendtii, and involves removing a small portion of the root with some stem attached. This can then be planted in the substrate, and will slowly develop into a new plant.
One common practice is to pull mature plants apart, creating numerous new plants which can then be spread across the aquarium or sold to others.

Cryptocoryne wendtii tends to stay relatively small, and is best as a foreground or midground plant in aquariums. It grows thickly, and can be used to cover up unsightly portions of other plants, or simply as a focal point in an aquarium.
Revere, set my mind at rest, I could not remember if this lovely plant should have been unplanted i.e. tied to Rick, branch or popped in substrate
Well written and informative, much appreciated thank you
They have a rhizome, but do indeed need something for their roots to grab.. usually this is substrate, but the right chunk of wood can have a crypt jammed into its crevices nicely…
Hi. Recently purchased a potted bronze. Should I leave it in the pot or remove It?
As long as you have proper substrate, you should definitely remove it from the pot.
