How to Propagate Cryptocoryne Wendtii from Runners

Cryptocoryne wendtii is a rosette crypt propagated by runners and rhizome division. Learn how to split daughter plants and handle crypt melt after relocation.

Overview

Cryptocoryne wendtii is one of the most robust and easy crypts, a rosette plant native to Sri Lanka that grows from a rhizome and root crown rather than a cuttable stem. It is highly variable under different light and other conditions, appearing in green, brown, and red forms. Like other crypts it is propagated by runners, never by topping.

Propagation Method: Runners and Division

An established wendtii sends out runners along the substrate that grow into new daughter plants, and a mature clump can also be lifted and divided at the rhizome. Because it is commercially grown emersed, freshly bought plants often arrive in a different leaf form and may melt before regrowing submerged leaves from the rhizome.

Step-by-Step

Let the mother plant settle into a nutrient-rich substrate and grow undisturbed.
Watch for runners that raise new daughter rosettes nearby.
To split by division, gently lift the clump and separate it into sections, each with rhizome and roots.
Detach well-rooted daughter plants by cutting the connecting runner.
Replant each piece, burying the roots but leaving the crown above the substrate, and add a root tab nearby.

Conditions for Healthy Growth

Wendtii does not require high light and thrives in low-light, low-tech tanks. As a root feeder it prefers a nutrient-rich substrate; root tabs placed near the roots keep it fed. CO2 is not required. Stable water and a quality LED designed for planted tanks support steady runner production.

Lighting: low light is sufficient
Substrate: nutrient-rich; add root tabs for this root feeder
CO2: not required
Growth: slow but reliable once established

Maintenance

Maintenance is minimal. Leave the rhizome and crown above the substrate, top up root tabs as they deplete, and thin runners only when the clump crowds its neighbours. There is no need to trim leaf tops the way you would a stem plant.

Common Challenges

The classic issue is crypt melt: when moved to a new tank or after a big water change, the plant absorbs and sheds its existing leaves to conserve energy, then grows fresh leaves and roots adapted to the new environment. Do not pull the plant during a melt; if the rhizome is firm, leave it in place and it will regrow.
