How to Care for Monadenium guentheri

Light

In its native habitat, the Monadenium guentheri grows in a desert-like environment. But when the succulent is grown indoors as a houseplant, it needs full sun and bright light.

The best thing is to place the plants in a semi-shaded area because too much exposure to the rays of the sun can cause the stems and leaves to develop a reddish coloring.

If the succulent has been growing in the shade, then move the plant slowly into the sun to prevent it from getting sunburned.

Watering

The Monadenium guentheri succulent cannot withstand high humidity and so you must maintain the plant in low humidity conditions.

Since the Monadenium guentheri grows naturally in arid conditions and is drought-tolerant, the plant does not need a lot of water. The plant, however, needs more water during its growing season, preferably once per week.

Water the Monadenium guentheri only when the soil is dry. During the winter months i.e., from October to March, the plant goes dormant and it is best to stop watering it completely during this period.

The succulent does not do well when it is wet for prolonged periods and if overwatered, it can rot.

Soil

The Monadenium guentheri grows well in well-draining sandy soil that contains pumice, perlite, peat or river sand. You can also use a succulent soil mix that is quick draining.

If you’re growing the succulent in a pot, then ensure that the growing medium is airy, and contains non-organic materials like lava grit, peat, clay or pumice.

The aerial part of the Monadenium guentheri grows rather slowly, but the plant produces very large rhizomatous roots. And so, it is a good idea to repot the succulents every 2 to 3 years to ensure that they developed in a balanced manner.

Fertilizing

It is good to apply a diluted liquid fertilizer to the Monadenium guentheri once every 2 weeks during its growing period i.e., during summer and spring. Don’t fertilize the plant during winter and fall.

The succulent doesn’t like the cold because of its African origin and cannot tolerate freezing weather conditions. And so in winter, you should keep the plant indoors or in a heated greenhouse to protect it from the cold.

Pests and Diseases
