Stromanthe grows best in bright, indirect light. Too little light will result in loss of the beautiful variegation. Stromanthe Plants can also grow under flourescent light.

Keep your Stromanthe away from direct sunlight as it can lead to sunburn on leaves and washed out leaves.

Regularly turn the pot to ensure your plant receives light on all sides for uniform growth and prevent leggy growth. Check out this guide on understanding light for houseplants.

How to Water Stromanthe

Water Stromanthe thoroughly and keep the soil moist at all times during the growing season. Reduce watering in the cold season as growth is minimal at this time.

Being a tropical plant, water your Stromanthe with water that is at room temperature to avoid shocking the plant which can result in reduced growth.

Stromanthe Plants are sensitive to chemicals dissolved in water, therefore, water Stromanthe with water that is free of chlorine and flourides.

Ensure the pot for your Stromanthe has a drainage hole to prevent the soil from getting soggy as it can lead to root-rot.

Avoid wetting the foliage of your Stromanthe during watering or water from the bottom instead to prevent fungal infestation. Read more on how to water houseplants.

Humidity for Stromanthe

Stromanthe requires high humidity inorder to thrive. To raise humidity for your Stromanthe, surround the pot with wet moss or place the pot on a wet pebble tray. Check out these techniques on how to raise humidity for houseplants.

You can also grow your Stromanthe in a terrarium as a high humidity can be maintained in a terrarium. Read more on how to make a closed terrarium for houseplants.

How to Repot Stromanthe

Repot Stromanthe the beginning of the growing season only when it has become root-bound. Use a pot 1 size larger than the current one.

Stromanthes do not like to sit in soggy soil, therefore, ensure the soil is free-draining and the pot has a drainage hole as soggy soil can lead to root-rot.

The large Stromanthe plants can be divided at the time of repotting and the splits used to propagate new Stromanthe plants.

How to Prune Stromanthe

Pruning Stromanthe is easy as it involves removal of dead and yellow foliage to maintain the plant neat and attractive.

Cut back the stems at the beginning of the growing season to rejuvenate growth. Read more on how to prune houseplants.

Stromanthe Plant (Stromanthe triostar) Propagation

Stromanthe Plant propagation can be done at the beginning of the growing season by plant division.

How to propagate Stromanthe by plant division

Take out the Stromanthe plant from its pot and divide it into several sections. Ensure each section has some roots inorder to hasten rooting.

Pot the Stromanthe sections into individual pots in moist, free-draining soil. Ensure the pots have a drainage hole to prevent the soil from getting soggy as it can lead to rotting.

Cover the pots with clear polythene to create a greenhouse effect and maintain warm humid conditions which hasten establishment of your Stromanthe plants.

Place the pots in a warm, shaded place until new growth has emerged in the Stromanthe sections.

Gradually remove the polythene cover over a period of two weeks to acclimatize the new Stromanthe plants.

Then move the set up to a cool, shaded place and maintain the soil moist until the new Stromanthe plants are well established after which routine care can begin.
