PLANT OVERVIEW

About Cryptocoryne willisii

A small, grassy crypt for foreground-to-midground carpets.

Cryptocoryne willisii stays short with narrow green leaves and spreads by runners into a low, grassy patch. It's an easy way to get a crypt carpet effect in low-tech tanks where true carpeting plants would struggle.

PLANTING

How to plant it.

Substrate: Nutrient-rich substrate; root tabs help

Plant the crown just above the substrate; roots feed heavily.

GROWTH + PROPAGATION

What to expect after planting.

Propagation

Runners / daughter plants

Acclimation

Prone to "crypt melt" after a move or parameter change; usually regrows from the rhizome — leave it be.

COMMON PROBLEMS

What usually goes wrong.

Crypt melt after replanting or sudden parameter swings; slow to establish.
