Soil Requirements
Keysseria maviensis prefers well-draining soil, as its roots can easily rot in soils that are too moist. A well-balanced soil mix that includes perlite or sand to promote drainage is ideal. The soil pH should be moderate, between 6.0 and 7.0.
Cultivation methods
The Keysseria maviensis (Mann) Cabrera plant grows well in well-draining soils that are rich in organic matter. The plant requires adequate sunlight exposure for growth, and it is ideal to place it where it can get about six hours of sunlight daily. The plant thrives in warm temperatures with little or no frost, so it is best to plant them during the warmer months of the year.
If planting in a pot, ensure that the container is big enough for the plant to grow, has drainage holes, and is filled with well-draining soil. It is essential to fertilize the soil with nutrients that will encourage growth, and it is best to start with fertilizer at planting time.
Watering needs
Watering is essential for the growth and health of Keysseria maviensis. The plant requires moderate watering, and it is best to water it every three to four days. Water thoroughly and allow the soil to dry out between watering. However, ensure that the soil does not become too dry, as this will affect the plant's growth. Overwatering can also damage the plant, and it is essential to avoid this.
Fertilization
To achieve optimal growth, Keysseria maviensis requires regular fertilization. When planting, mix in a slow-release fertilizer into the soil. During the growing season, apply a balanced liquid fertilizer every two weeks.
Remember, the application of too much fertilizer can cause salt buildup in the soil, and this can damage the plant. It is imperative to follow the instructions on the fertilizer packaging and avoid overfertilization.
Pruning
Pruning Keysseria maviensis is not necessary, but it can help the plant maintain a neat and attractive appearance. Regular pruning helps the plant to maintain its shape and size. Trim off any dead or damaged leaves or stems. If the plant becomes too large, you can cut it back to the desired size. It is best to prune during the growing season, as this is when the plant is actively growing.

Here are some of the most common problems that one can encounter when growing Keysseria maviensis, as well as some recommended solutions for each:
Diseases
Powdery mildew: Powdery mildew is a fungal disease that is manifested by the presence of a white, powdery substance on the leaves, stems, and flowers of Keysseria maviensis. To prevent powdery mildew, it is important to avoid overcrowding the plants and to give them proper air circulation. If the disease has already developed, spraying with a solution of baking soda and water can help control its spread.
Leaf spot: Leaf spot is also a fungal disease that causes round, dark spots to appear on the leaves of the plant. To prevent this disease, avoid wetting the leaves when watering, as fungi thrive in moist environments. If the disease has already taken hold, it may be necessary to remove and dispose of the infected leaves to prevent further spread.
Pests
Spider mites: Spider mites are tiny pests that feed on the juices of the plant, leaving behind stippling and discoloration of the leaves. To control spider mites, one can simply spray the leaves with a strong stream of water, or introduce predatory mites that feed on spider mites.
Aphids: Aphids are another common pest that can attack Keysseria maviensis. They are soft-bodied insects that suck the sap out of the plant. To control aphids, one can simply wipe the leaves with a damp cloth or spray the plant with a solution of soap and water.
