Cryptocoryne usteriana is one of the taller cryptocorynes and is very easy to grow.
Leaves are 3-5 cm wide with an embossed surface; they can easily reach more than 50 cm length. With good light and fertilization, the upper side of the leaves will obtain a dark green or bronze-green colour while the back of the leaves will turn burgundy red. Propagation is by long runners, and the plant tolerates quite alkaline water very well.
Understanding Crypt melt - all Cryptocoryne species require stable water parameter and light conditions. Once planted, Crypts should not be moved otherwise it can trigger what is called Crypt melt. If a Crypt has a significant change of environment (ph, kh, gh, lighting intensity or duration, root disturbance etc), Crypt melt can be triggered. The leaves start to disintegrate as the plant prepares for its new environment - DO NOT WORRY! Your plant will begin to grow back over the next 30 days (sometimes sooner, sometimes later) - it's still very much alive and busy getting ready for the growth of new leaves. In the meantime, any decaying leaves should be trimmed and recycled in a compost bin.
