The plant can grow up to 15 feet tall, so ample space should be provided for mature growth. It can be propagated by seed or stem cutting. When propagating by stem cutting, make sure to take cuttings from the tips of branches with at least two nodes, and plant them in moist soil with good drainage.
When planting in the ground, dig a hole that is twice the size of the root ball and mix in some organic matter like compost or peat moss. After planting, water the plant thoroughly and keep the soil moist until it has established.
Watering needs of Aralia bicrenata Woot. & Standl.
Aralia bicrenata Woot. & Standl. requires regular watering to keep the soil moist, but not waterlogged. It is important to avoid letting the soil dry out completely, especially during the hot summer months or in areas with low humidity.
When watering, make sure to saturate the soil around the roots. It is best to water in the morning or evening when the temperature is cooler to reduce evaporation and water loss. Over-watering may cause root rot, and the plant may become susceptible to other diseases.
Fertilization of Aralia bicrenata Woot. & Standl.
Aralia bicrenata Woot. & Standl. benefits from regular fertilization during the growing season to keep it healthy and encourage robust growth. A balanced, slow-release fertilizer with a higher nitrogen content can be applied in the spring and again in mid-summer.
Avoid fertilizing late in the season as it may stimulate new growth that may not have time to harden off before winter, making it more susceptible to cold damage.
Pruning of Aralia bicrenata Woot. & Standl.
Pruning is not necessary for the health of Aralia bicrenata Woot. & Standl., but it can help maintain its shape and size. Pruning can be done in the late winter or early spring before new growth appears.
When pruning, remove any dead or damaged branches first. For shape and size, branches can be trimmed back to a lateral branch or bud. Branches above a certain height can be pruned to the desired height to control the overall size, but avoid cutting back more than a third of the overall plant, as it can lead to stress and reduced vigor.
Propagation of Aralia bicrenata Woot. & Standl.
Aralia bicrenata, commonly known as the "Chinese angelica tree," is a perennial plant species that is native to China and Taiwan. This plant is commonly grown for its ornamental leaves, which can add beauty to any garden. Aralia bicrenata is propagated through various methods. Below are the propagation techniques that can be used to propagate this plant.
Seed propagation
Seed propagation is the most common method of propagating Aralia bicrenata. The seeds of Aralia bicrenata can be obtained from the plant's flowers, which are pollinated by insects. Once the seeds are harvested, they can be sown in a seed tray filled with a mixture of sand, peat, and vermiculite. The tray should be placed in a warm, sunny area and regularly watered to keep the soil damp. The seeds will typically germinate within two to three weeks.
Cuttings propagation
Another method of propagating Aralia bicrenata is through cuttings. This propagation technique is effective because the cuttings will root quickly, resulting in a faster-growing plant. Stem cuttings are the most effective type of cutting for this species. To propagate Aralia bicrenata through cuttings, take a 6-inch long cutting from the plant's stem, making sure it has at least two leaf nodes. Dip the end of the cutting in rooting hormone and plant it in a well-draining potting mix. Place the cutting in a warm, well-lit area and keep the soil moist. The cutting should root in four to six weeks.
Air layering propagation
Aralia bicrenata can also be propagated through air layering. This technique involves inducing roots to form on a stem that is still attached to the mother plant. To air layer Aralia bicrenata, select a healthy stem and remove a section of bark from around the stem halfway between two nodes. Dust the exposed section with rooting hormone and wrap the area with moist sphagnum moss. Cover the moss with plastic wrap, making sure it is sealed tightly. After the roots have formed, cut the stem and plant it in a well-draining soil mix.
Conclusion
Propagation of Aralia bicrenata can be done through several methods, including seed propagation, cuttings propagation, and air layering propagation. No matter which method you choose, remember that the key to successful propagation is providing the plant with optimal growing conditions, including proper lighting, watering, and fertilizing. With proper care, your Aralia bicrenata plant will flourish and provide you with beautiful foliage for years to come.
