Propagation of Streptocarpus milbraedii Engl.
Streptocarpus milbraedii Engl. is a popular indoor plant that is mainly propagated from leaves and offsets. The plant can also be propagated from seeds.
Propagation from Leaves
The leaves of Streptocarpus milbraedii Engl. can be used to propagate new plants. Take a healthy mature leaf from the parent plant and cut it into small pieces. Each piece should have at least one vein and a small piece of petiole attached. Dust some rooting hormone on the base of each leaf piece and insert it into a pot filled with a well-draining potting mix. Water the pot and cover it with a clear plastic bag to create a humid environment. Place the pot in a warm place with indirect sunlight. The cuttings should root within 3-4 weeks. Once the new plantlets have several leaves, they can be transplanted to individual pots.
Propagation from Offsets
Streptocarpus milbraedii Engl. produces offset plantlets that can be used to propagate new plants. Wait until the offsets are of a good size, then gently separate them from the parent plant. Each offset should have at least a few leaves and roots. Plant the offset into a well-draining potting mix and water it thoroughly. Cover the pot with a clear plastic bag to create a humid environment. Place the pot in a warm place with indirect sunlight. The new plantlet should thrive and grow into a mature plant.
Propagation from Seeds
Propagation of Streptocarpus milbraedii Engl. from seeds is possible, but it is not commonly practiced. Sow the seeds onto the surface of a well-draining potting mix and cover them with a thin layer of the mix. Keep the soil moist but not waterlogged. Cover the pot with a clear plastic bag to create a humid environment. Place the pot in a warm place with indirect sunlight. Germination should occur within 2-3 weeks. Once the seedlings have several leaves, they can be transplanted to individual pots.
