Propagation of Tripteris limonifolia DC.
Tripteris limonifolia DC., also called Lemon-scented tripteris, is a perennial plant that is mainly propagated through seed. In its natural habitat, this plant self-seeds, and young seedlings can be found growing around the base of mature plants. Cultivators can also easily propagate this plant by collecting and sowing the seeds during the warmer months.
Seed Collection
The seeds of Tripteris limonifolia DC. mature in late summer, and the seed heads should be collected when they turn brown. After collecting the seed heads, they should be hung upside down in a dry, warm place, away from direct sunlight, for a few days to allow them to dry completely.
Seed Sowing
Once the seeds are dry, they can be removed from the seed heads and sown directly in the ground or in individual pots. If sowing directly in the ground, ensure that the seeds are sown roughly 2 cm deep and 10 cm apart. On the other hand, if sowing in individual pots, the seeds should be sown in a well-draining, sterile potting mix, and placed in a bright, warm spot. The potting mix should be kept moist, and as soon as the seedlings emerge, they should be placed in a sunny location.
Division
Tripteris limonifolia DC. can also be propagated through division, however, this method is not commonly used. In this method, mature plants are lifted and divided into several smaller parts, each with its roots and shoots. The divided parts can be replanted and watered regularly until they establish themselves.
Disease and Pest Management for Tripteris limonifolia DC.
Tripteris limonifolia DC. is a hardy annual plant species that belongs to the Asteraceae family. It has a strong resistance to diseases and pests, thanks to the presence of chemical compounds such as flavonoids, alkaloids, and terpenes.

Below are some common pests and diseases that can affect the plant and ways to manage them.
Pests
Aphids: Aphids are sap-sucking insects that feed on the plant's leaves, stems, and flowers, leading to stunted growth and deformation. To manage aphids, spray the plant with a strong stream of water to dislodge them physically. Use insecticidal soap or neem oil to control the pest further.
Spider mites: Spider mites are tiny arachnids that feed on plant sap, yellowing the leaves and causing them to fall off. To manage spider mites, use a strong stream of water to wash the plant. You can also introduce predatory mites to control their spread.
Whiteflies: Whiteflies are tiny flies that feed on the plant's sap, causing yellowing and wilting of the leaves. To control this pest, introduce parasitic wasps. Alternatively, use neem oil or insecticidal soap to suffocate the whiteflies.
Leafhoppers: Leafhoppers are small insects that suck sap from the underside of the plant's leaves. To manage leafhoppers, introduce natural predators such as lacewings or ladybugs. You can also use insecticidal soap or horticultural oil to control their spread.
Diseases
Powdery Mildew: Powdery mildew is a fungal disease that appears as a white or grey powdery coating on the plant's leaves, stems, and flowers. To manage powdery mildew, maintain good air circulation and avoid overcrowding. You can also use fungicides containing potassium bicarbonate and neem oil to control the disease.
Root rot: Root rot is a fungal disease that attacks the plant's roots, leading to wilting, yellowing, and death of the plant. To manage root rot, avoid overwatering and provide adequate drainage. You can also use soil drenches containing fungicides such as copper oxychloride to control the disease.
Anthracnose: Anthracnose is a fungal disease that affects the plant's stems, leaves, and flowers, causing them to turn brown or black and die. To manage anthracnose, maintain good air circulation and avoid overcrowding. You can also use fungicides containing chlorothalonil to control the disease.
