Ctenanthe lubbersiana, a Marantaceae XXL

Your Ctenanthe lubbersiana likes its soil to be moist. But it hates excess water. Water when the surface of the substrate is dry (about a centimetre).

Use room-temperature, non-calcareous water, such as rainwater.

Drain any water that collects in the saucer or planter. It may rot the roots.

Ctenanthes lubbersiana plants require a high level of humidity. Spray foliage with non-calcareous water, preferably rainwater.

In spring, transfer your Ctenanthe lubbersiana to a larger pot, so that it can continue to grow.

Choose a pierced pot one-third larger than the previous one. Choose width rather than height to allow roots to develop. Choose a plastic or ceramic container rather than a clay one. The latter tend to absorb water more quickly.

Install a bed of clay balls and cover it with potting soil for indoor plants. Don't hesitate to mix in some perlite to optimize drainage. Then place the rootball and add potting soil until you reach a centimetre or two below the rim of the pot. Tamp down to avoid air bubbles.

You can stimulate the development of your plant during its growth phase, in spring and summer, with fertilizer.

Feed your Ctenanthe lubbersiana with green plant fertilizer.

Dust prevents leaves from absorbing light and slows photosynthesis. You can use a brush or feather duster to clean the foliage.

Remove wilted and yellowed leaves.

Cutting is carried out during the strong growth phase, generally in spring and early summer.

Gently dig up your Ctenanthe lubbersiana. Locate a rhizome on the periphery, with several roots and even leaves. Separate it using a clean, sharp tool, such as disinfected secateurs.

In a pierced pot, pour a layer of clay balls for drainage. Add potting soil for seedlings and planting.

Using a pencil, make a pilot hole and plant your cutting.

Water at room temperature to help the plant take root.
