Propagation of Thermopsis macrophylla Hook. & Arn. var. hitchcockii Isely
Thermopsis macrophylla Hook. & Arn. var. hitchcockii Isely, commonly known as Hitchcock's goldenbanner, can be propagated through seeds and division.
Propagation through seeds
The seeds of Hitchcock's goldenbanner can be collected in autumn, when the pods have turned brown and dry. The seeds can then be cleaned and stored in a cool, dry place until sowing time.
The seeds should be sown in early spring in a well-draining soil mix, either indoors or directly in the garden. They should be sown at a depth of 1/4 inch and spaced about 12 inches apart. Germination typically takes 2-3 weeks.
The seedlings should be kept moist but not waterlogged. Once the seedlings have developed a few leaves, they can be transplanted to their final location in the garden. It is advisable to protect the seedlings from direct sunlight for the first few days after transplanting to prevent wilting.
Propagation through division
Hitchcock's goldenbanner can also be propagated through division, which is best done in early spring or late summer.
The plant should be dug up carefully, taking care not to damage the roots. The clump can then be divided into smaller sections with a sharp knife or garden fork. Each section should have a healthy root system and at least one shoot.
The divided sections can then be replanted in a well-draining soil mix at the same depth as before. They should be watered well and kept moist until they establish themselves.

To manage root rot, ensure proper drainage in the soil and avoid overwatering the plant. Use a well-draining soil mix and sterilize the soil before planting.
2. Powdery mildew: Powdery mildew is a fungal disease that affects the leaves, stems, and flowers of the plant. Symptoms include a white powdery coating on the plant's surface, which can cause leaf wilting and distortion. To manage powdery mildew, remove infected parts of the plant and avoid overhead watering. Apply fungicides to the plant as a preventive measure.
3. Leaf spot: Leaf spot is a fungal disease that affects the leaves of the plant. Symptoms include yellow or brown spots on the leaves, which can cause defoliation and stunted growth. To manage leaf spot, remove infected parts of the plant and avoid overhead watering. Apply fungicides to the plant as a preventive measure.
Pests
1. Aphids: Aphids are small, soft-bodied insects that feed on the sap of the plant. Symptoms of aphid infestation include curling of leaves and stunted growth. To manage aphids, spray the plant with a strong jet of water to dislodge them. Alternatively, use insecticidal soap or neem oil to control the population.
2. Spider mites: Spider mites are tiny arachnids that feed on the plant's sap. Symptoms of spider mite infestation include yellowing of leaves and the presence of webbing on the plant's surface. To manage spider mites, isolate the infected plant and avoid overcrowding. Introduce natural predators such as lady beetles and predatory mites. Alternatively, use insecticidal soap or neem oil to control the population.
3. Slugs and snails: Slugs and snails are mollusks that feed on the plant's leaves and stems. Symptoms of infestation include irregularly shaped holes in the leaves and slime trails on the plant's surface. To manage slugs and snails, handpick them from the plant and dispose of them.
