Propagation of Impatiens Mildbraedii Gilg Subsp. Mildbraedii
Propagation of Impatiens Mildbraedii Gilg Subsp. Mildbraedii can be done through two methods, namely:
Seed Propagation
Impatiens Mildbraedii Gilg Subsp. Mildbraedii can be propagated through seeds. The seeds are tiny, so they need to be handled carefully. Sow the seeds on the surface of the soil and keep them moist. The optimal temperature for germination is between 20 - 25°C. Germination may take up to three weeks. Once the seedlings have grown a few leaves, they can be transplanted to their own pots with a mixture of peat and sand. The seedlings should be kept in a warm and humid environment to facilitate their growth.
Stem Cutting Propagation
Another method is propagating Impatiens Mildbraedii Gilg Subsp. Mildbraedii using stem cuttings. Select healthy stem cuttings with 2-3 pairs of leaves and cut them at an angle. Remove the lower leaves and dip the cut end in rooting hormone. Then, place the cutting in a pot with a soil mixture of peat and sand. Keep the cutting moist and in a warm and humid environment. After a few weeks, the roots will grow and the cutting can be transplanted to its own pot.
