Make sure to cut the branches at a 45-degree angle using clean and sterilized shears. Regular pruning will help keep the plant healthy and promote vigorous growth and beautiful blooms.
Propagation of Nasturtium stylosum Shuttlw. ex O.E. Schulz
Nasturtium stylosum can be propagated by different methods which include:
Seed Propagation
The most common method of propagation for Nasturtium stylosum is through seeds. The seeds can be collected from previous plants or purchased from a garden store. To propagate from seeds, prepare a seedbed or flat with moist soil, place the seeds on top of the soil, and cover them with a thin layer of soil. Water the soil regularly and keep it moist until the seeds germinate, which usually takes about 2-3 weeks. Once seedlings appear, transplant them into individual pots or into the ground, making sure to give them enough space to grow.
Cutting Propagation
Nasturtium stylosum can also be propagated through stem cuttings. Select healthy stems from the parent plant and cut them into sections about 6 inches long. Remove the lower leaves and plant the cuttings in a prepared pot or container filled with moist soil and some sand. Keep the cuttings in a shaded spot and water them regularly until roots develop, which usually takes about 3-4 weeks. Once rooted, transplant the new plants into individual pots or into the ground.
Division Propagation
Another way to propagate Nasturtium stylosum is through division. This method is best done in the spring or fall when the plant is not in active growth. To divide the plant, carefully dig up the entire root system and separate it into sections, making sure each section has some roots and at least one stem. Replant each divided section into the ground or in individual pots filled with moist soil. Water regularly until the new plants establish.
