Propagation of Felicia angustifolia (Jacq.) Nees var. glabra DC.
Felicia angustifolia (Jacq.) Nees var. glabra DC. can be propagated by seeds, cuttings, and division of rhizomes.
Propagation by Seeds
Propagation by seeds is a common method of propagating Felicia angustifolia (Jacq.) Nees var. glabra DC. Seeds can be sown directly on the garden soil in the spring. The seeds should be sown in a well-prepared, weed-free seedbed. The seedlings should be thinned out to allow proper spacing. Germination can be improved by soaking the seeds in warm water overnight or scarifying the seeds before sowing.
Propagation by Cuttings
Propagation by cuttings is another way to propagate Felicia angustifolia (Jacq.) Nees var. glabra DC. Take 5-10 cm long stem cuttings from the plant in the spring or early summer. The cuttings should be taken from the lateral shoots that are not flowering. Remove the lower leaves and dip the cuttings in rooting hormone. Plant the cuttings in a well-draining potting mix and keep it moist. The cuttings should root in 3-4 weeks, and when the roots are established, they can be transplanted in the garden.
Propagation by Division of Rhizomes
Felicia angustifolia (Jacq.) Nees var. glabra DC. can also be propagated by division of rhizomes. This method is best done in the spring or fall. Dig up the parent plant and remove the rhizomes from the outside of the clump. Cut the rhizomes into sections, making sure each section has several shoots. Re-plant the sections in the garden and keep them well-watered until they are established.
Disease Management
Felicia angustifolia (Jacq.) Nees var. glabra DC. is susceptible to various diseases, including fungal and bacterial infections.
The symptoms of fungal infection include wilting, yellowing of leaves, and twisting and distortion of plant parts. Powdery mildew is a fungal disease that appears as a white powdery coating on the leaves and stems. It can be controlled by removing affected parts and spraying the plant with a fungicide. Another common fungal infection is leaf spot, which causes brown or black spots on leaves. The infected leaves should be removed to prevent the spread of the disease.
Bacterial infections can cause leaf blight, soft rot, and stem canker. The symptoms include leaf yellowing and browning, wilting, and girdling of stems. There is no cure for bacterial infections, so the infected areas should be removed and destroyed.
Pest Management
Felicia angustifolia (Jacq.) Nees var. glabra DC. is also susceptible to attack from pests such as aphids, spider mites, and thrips.
Aphids are small, soft-bodied insects that suck sap from the plant, causing leaf curling and yellowing. They can be controlled by washing the plant with soapy water or spraying with insecticidal soap.
Spider mites are tiny pests that feed on the leaves, causing yellowing and stippling. They can be controlled by spraying the plant with water to increase humidity and applying a miticide.
Thrips are small insects that feed on the flowers, causing distortion and discoloration. They can be controlled with insecticidal soap, neem oil, or pyrethrin.
Regular monitoring and early identification of pests and diseases are essential for effective management of Felicia angustifolia (Jacq.) Nees var. glabra DC.
