It should be noted that this plant is susceptible to root rot if the soil is too wet. Therefore, it is important to ensure that the soil is well-drained and not waterlogged.
Cultivation methods
Streptocarpus molweniensis Hilliard subsp. molweniensis can be grown both indoors and outdoors. It is a tropical plant that requires warm and humid conditions to thrive. It can be propagated through seeds, division, or leaf cuttings. The plant prefers well-draining soil with a pH ranging from 6.0 to 7.5. Additionally, it thrives in partially shaded areas with indirect sunlight.
Watering needs
Streptocarpus molweniensis Hilliard subsp. molweniensis requires consistently moist soil. Overwatering can lead to root rot, while under-watering can cause the leaves to wilt. It is recommended to water the plant when the top inch of soil feels dry to the touch. The frequency of watering will depend on the temperature, humidity, and sunlight conditions. It is important to avoid getting water on the foliage to prevent fungal diseases.
Fertilization
Streptocarpus molweniensis Hilliard subsp. molweniensis can benefit from regular fertilization during the growing season. It is recommended to use a balanced fertilizer with a 1:1:1 ratio of nitrogen, phosphorus, and potassium. The fertilizer should be diluted to half-strength and applied every four to six weeks.

Propagation of Streptocarpus molweniensis Hilliard subsp. molweniensis
Streptocarpus molweniensis Hilliard subsp. molweniensis can be propagated by several methods including:
Leaf cuttings
One of the easiest ways to propagate Streptocarpus molweniensis Hilliard subsp. molweniensis is through leaf cuttings. Choose a mature and healthy leaf, and remove it with a sharp, sterile blade. Cut the leaf into sections, making sure that each section has a piece of vein attached to it.
