Light Requirements
Hamamelis virginiana L. var. henryi Jenne prefers partial shade to full sun conditions.
Temperature Requirements
This plant thrives in temperate zones and prefers a cool climate. The ideal temperature range for growth is between 10-25°C (50-77°F). During winter, the plant can tolerate temperatures below freezing point.
Soil Requirements
The plant grows well in well-drained, fertile loam soil that has a pH range of 4.5 to 7.5. It prefers a soil that is moist but not waterlogged. The soil's rich organic matter content is beneficial to the growth of this plant.
Cultivation
Hamamelis virginiana L. var. henryi Jenne, also known as Henry's witch hazel, is a deciduous shrub that grows well in full to partial sunlight. It is suitable for USDA zones 3 to 8, and prefers well-draining, slightly acidic soil. The plant can grow up to 15 feet tall, with a spread of up to 12 feet.
The best time to plant Henry's witch hazel is in the fall, after the leaves have fallen. This allows the shrub to establish its root system before the hot summer months. The plant can also be propagated through hardwood cuttings, taken during the dormant season.
Watering Needs
Henry's witch hazel has moderate water needs and can tolerate occasional periods of drought. However, the plant should be watered regularly during the first year after planting to help establish its roots. Water the plant deeply, once or twice a week, making sure the soil is moist but not waterlogged. Avoid getting water on the leaves, as this can promote fungal diseases.
Fertilization
Henry's witch hazel does not require much fertilization, as excessive nitrogen can promote leaf growth at the expense of flower production. If the soil is poor, you can apply a slow-release, balanced fertilizer in early spring, just before new growth appears. Alternatively, you can add compost or well-rotted manure to the soil surface in the fall, as a natural fertilizer.
Pruning
Pruning is not necessary for Henry's witch hazel, as the shrub has a naturally attractive shape. However, you can remove any dead, damaged, or crossing branches to improve air circulation and prevent disease. If you want to control the size of the plant, you can selectively prune the tips of branches after flowering, but avoid cutting back into old wood, as this can damage the shrub.
Propagation of Hamamelis virginiana L. var. henryi Jenne
Hamamelis virginiana L. var. henryi Jenne, commonly known as Witch hazel, is a deciduous shrub that can be propagated by several different methods. The following are the most effective propagation methods:
Seed Propagation
Seed propagation is the most common way to propagate Hamamelis virginiana L. var. henryi Jenne. The seeds are ready for planting in late summer. The seeds should be collected and sown immediately. The seeds should be sown in a peat-based mixture in a container that is at least 2 inches deep. The container should be placed in a shaded area and kept moist. The seeds will germinate within 3 to 8 weeks after planting. Once the seedlings have grown to a height of 2 to 3 inches, they can be transplanted to their permanent location.
Cuttings Propagation
Cuttings propagation is another effective way to propagate Hamamelis virginiana L. var. henryi Jenne. The cuttings should be taken during the late spring or early summer when the plant is actively growing. The cuttings should be at least 4 inches long and should be taken from the previous year's growth. The cuttings should be dipped in rooting hormone and planted in a mixture of half peat moss and half sand. The container should be placed in a shaded area and kept moist. After 6 to 8 weeks, the cuttings should have roots and can be transplanted.
Layering Propagation
Layering propagation is a simple way to propagate Hamamelis virginiana L. var. henryi Jenne. In the spring, the lower branches of the plant should be covered with soil or mulch. The soil or mulch should be about 2 inches deep. The branches should be secured to the ground with a U-shaped wire. The branches will then grow roots over the next several months. Once the branches have developed a good root system, they can be separated from the main plant and transplanted to their permanent location.
Disease Management
Hamamelis virginiana L. var. henryi Jenne is a relatively disease-resistant plant. However, like all plants, it may suffer from certain diseases that can affect its growth and health. One of the most common diseases that may affect this plant is leaf blight caused by the fungus Phyllosticta hamamelidis. Symptoms of leaf blight include black spots on the foliage that may spread to the stem and petioles, causing defoliation if left untreated. To manage leaf blight, it is recommended to remove all infected leaves and stems and to apply a fungicide such as copper fungicide or neem oil. It is also important to ensure adequate air circulation around the plant to prevent moisture buildup, which can encourage fungal growth.
Another disease that may affect this plant is powdery mildew caused by the fungus Podosphaera leucotricha. Powdery mildew appears as a white, powdery growth on leaves, stems, and flowers, causing distortion and stunted growth. To manage powdery mildew, it is recommended to prune affected plant parts, increase air circulation, and apply a fungicide such as potassium bicarbonate or sulfur spray.
Pest Management
Hamamelis virginiana L. var. henryi Jenne is relatively pest-resistant, but there are a few insects that may infest this plant. One of the most common pests is the spider mite, which appears as tiny reddish-brown specks on the foliage, causing yellowing and leaf drop. To manage spider mites, it is recommended to wash the plant with a strong jet of water, prune affected plant parts, and apply insecticidal soap, neem oil, or a miticide.
Another possible pest is the scale insect, which appears as small bumps on the foliage and stems, sucking sap from the plant and causing yellowing and wilting. To manage scale insects, it is recommended to prune affected plant parts, apply insecticidal soap or neem oil, and introduce natural enemies such as ladybugs or lacewings.
