Pruning of Heliopsis helianthoides (L.) Sweet ssp. occidentalis T.R. Fisher
Heliopsis helianthoides (L.) Sweet ssp. occidentalis T.R. Fisher does not require much pruning. However, deadheading (removing spent flowers) promotes prolonged blooming and helps to maintain the plant's appearance. Cut the spent flowers back to the nearest node or bud. The plant can also be cut back to its base after it has finished blooming, which helps to encourage new growth and prevents the plant from becoming too woody.
Propagation of Heliopsis helianthoides ssp. occidentalis
Heliopsis helianthoides ssp. occidentalis, commonly known as western oxeye, can be propagated through several methods, including seed propagation and cuttings.
Seed propagation
Seeds of Heliopsis helianthoides ssp. occidentalis can be sown directly into the ground after the last frost. The soil should be well-draining and slightly acidic. Seeds should be sown at a depth of approximately 1/8 to 1/4 inch deep, and the soil should be kept moist until the seedlings emerge.
Alternatively, seeds can be started indoors 4-6 weeks before the last frost. For indoor sowing, seeds should be sown on the surface of a moist, well-draining soil mix and lightly covered with soil. The soil should be kept moist and warm until the seedlings emerge. Once the seedlings have developed their first true leaves, they can be transplanted into individual pots or directly into the ground.
Cuttings
Cuttings can be taken from Heliopsis helianthoides ssp. occidentalis in the summer when the plant is actively growing. Cuttings should be taken from non-flowering shoots that are approximately 4-6 inches long and should be taken from the top of the plant. The bottom leaves should be removed, and the remaining leaves should be cut in half to reduce water loss.
The cuttings should be planted in a well-draining soil mix and kept moist until roots develop, which typically takes 3-5 weeks. Once the cuttings have developed roots, they can be transplanted into individual pots or directly into the ground.
Disease Management
Several diseases can affect Heliopsis helianthoides ssp. occidentalis, including:
- Powdery Mildew: This fungus forms a powdery white coating on the leaves of the plant. It can be managed by watering the soil instead of the foliage, providing proper air circulation, and using a fungicide if necessary.
- Rust: This fungal disease can cause orange or brown spots on leaves. Infected leaves should be removed and destroyed, and the plant should be treated with a fungicide.
- Verticillium Wilt: This fungus can cause wilting, yellowing, and stunting of the plant. There is no cure, so infected plants should be removed and destroyed. Do not replant in the same area for several years.
Pest Management
Several pests can also attack Heliopsis helianthoides ssp. occidentalis, including:
- Aphids: These small insects can cluster on the leaves and stems, sucking sap from the plant and causing yellowing and stunting. They can be managed by spraying the plant with a strong stream of water or using insecticidal soap.
- Spider Mites: These tiny pests can cause yellowing and webbing on the plant. They can be managed by increasing humidity around the plant or using insecticidal soap.
- Caterpillars: These larvae can eat the leaves of the plant, causing defoliation and stunting. They can be managed by handpicking or using a biological control such as Bacillus thuringiensis.
Regular monitoring of the plant and prompt action to manage any pests or diseases that are detected can help to keep Heliopsis helianthoides ssp. occidentalis healthy and productive.
