Organic fertilizers will not only supply the essential nutrients but also help in retaining the moisture in the soil.
Pruning of Nemesia chamaedrifolia Vent.
Nemesia chamaedrifolia Vent. requires regular pruning to control its growth and promote blooming. Pruning should be done as soon as the blooming season is over. It can be done in the fall or spring. Remove the dead flowers and stems to encourage new growth. Pruning also helps in maintaining the shape of the plant. While pruning, it is recommended to use clean pruning shears to avoid any transfer of diseases from one plant to another.
Propagation of Nemesia chamaedrifolia Vent.
Nemesia chamaedrifolia Vent. can be propagated by both sexual and asexual methods. The plant is a short-lived perennial that is commonly grown as an annual. It is a popular ornamental plant with beautiful flowers that bloom in various colors such as yellow, white, pink, orange, and purple.
Propagation by Seeds
The easiest way to propagate Nemesia chamaedrifolia Vent. is by seed. The plant produces a large number of seeds, and they can be collected from mature seedpods when they turn brown. The seeds can be sown directly in the ground in spring or fall, or they can be started indoors in pots a few weeks before the last frost date. The optimal germination temperature for Nemesia chamaedrifolia Vent. is around 20-25°C.
Propagation by Cuttings
Nemesia chamaedrifolia Vent. can also be propagated by stem cuttings. The best time to take cuttings is in the summer when the plant is actively growing. Cuttings should be taken from healthy, non-flowering stems and should be about 7-10 cm long. Remove the leaves from the bottom half of the stem, dip the cut end in rooting hormone, and plant the cutting in a pot filled with moist, well-draining soil. Cover the pot with a plastic bag to increase humidity and place it in a bright, warm spot. Keep the soil moist but not waterlogged until the cutting starts to develop roots, which usually takes about 4-6 weeks.
Propagation by Division
Nemesia chamaedrifolia Vent. can also be propagated by division. This should be done in spring when the plant is just beginning to come out of dormancy. Gently dig up the plant and carefully separate the root ball into several smaller sections, making sure that each section has some roots and shoots. Replant the sections in well-prepared soil, and water them well. It may take a few weeks for the plants to recover from the shock of being divided, but they should start to grow again in no time.
