Cryptocoryne Willisii

Slender, lance-shaped leaves in green to olive-brown, growing as a low rosette that spreads by runner. Cryptocoryne willisii is one of the smaller crypts — the one to use when you want a foreground that fills in by itself instead of needing weekly trimming.

Grower's Notes

• It carpets, slowly, and then stays put. Willisii sends runners under the substrate and fills in around itself. Plant the portions a couple of inches apart and leave them — in a year you have a low, dense stand that a carpeting stem plant could not hold without constant trimming and CO₂.
• Expect it to melt after planting. Crypts drop their leaves on a change of conditions and rebuild from the roots over two to four weeks. Do not pull them out.
• Plant the crown at substrate level. Bury the roots and leave the growing point exposed. A buried crown rots from the center.
• Feed the roots. Crypts take almost everything from the substrate. Root tabs or aquasoil give full leaves; inert sand with liquid dosing gives short pale ones.
• Place it once. Every move triggers another melt and interrupts the runners.
