Overview
Eriogonum dendroideum (Nutt.) S. Stokes commonly known as Bushy Buckwheat is a shrub species native to California and western North America. It belongs to the family Polygonaceae.
Appearance
The plant grows up to 3-5 feet in height with several dense leafy stems emerging from a woody base. The stems have a reddish-brown color, while the bark is grayish-green and smooth. The leaves are relatively small and dark green in color, generally having a leathery texture, and are arranged alternately along the stem. The flowers of the plant are tiny, measure less than 0.25 inches in diameter, and are generally cream or white in color.
Uses
Eriogonum dendroideum has some medicinal uses. The roots and leaves of the plant have been used in traditional medicines by indigenous people to treat stomachache, colds, and fevers. However, the plant is not commonly used for medicinal purposes today. Bushy Buckwheat is mostly valued for its ornamental qualities and is used in xeriscaping landscapes, rock gardens, and native plant gardens. It is also an important plant species for soil stabilization and erosion control because it has a deep root system that can prevent soil loss even in extreme environmental conditions.
Common Names
The common names of Eriogonum dendroideum include Bushy Buckwheat, Tree Eriogonum, and Shrub Buckwheat.
Overall, Eriogonum dendroideum is a beautiful plant that offers numerous benefits to the environment and human beings.Light Requirements
Eriogonum dendroideum grows best in full sun exposure which means the plant should receive a minimum of 6 hours of bright, direct sunlight on a daily basis. The plant can tolerate partial shade but too much shading will interfere with its growth and flowering ability.
Temperature Requirements
Eriogonum dendroideum grows well in areas with Mediterranean climate featuring cool wet winters and dry summers. The plant is adapted to surviving under a variety of temperature conditions and can tolerate both hot and cold temperatures. E. dendroideum can thrive in temperatures ranging between 20°C to 30°C during the day. During the night, the plant also requires temperatures between 5°C and 10°C.
Soil Requirements
The plant tends to grow well in well-drained soils that are slightly acidic to alkaline in nature. The soil should be fertile enough with high organic matter content to help boost growth. E. dendroideum grows in a range of soils including sandy loams, clay loams, and rocky soils. However, a soil that is too dense with poor drainage can lead to root rot or other plant diseases that can stunt growth.
Cultivation methods
Eriogonum dendroideum, commonly called the tree buckwheat, is a shrub that is native to California. It grows up to 10 feet tall and has a spread of 6 feet. This plant thrives in full sun and well-draining soil. It can tolerate a wide range of soil types, including sandy and clay soils. While it can grow in areas with low rainfall, it prefers moderate watering conditions. This shrub is suitable for landscapes, gardens, and naturalized areas as it adds natural beauty.
Watering needs
Eriogonum dendroideum requires regular watering during the first year of planting to establish healthy roots. Watering should be done deeply to encourage the plant's roots to move deeper into the soil. After the first year, the plant is relatively drought-resistant and needs watering only when rainfall is scarce. However, providing occasional watering can help the shrub flourish even in dry regions. As a rule of thumb, Eriogonum dendroideum needs watering once a week in the absence of sufficient rainfall.
Fertilization
The Eriogonum dendroideum shrub doesn't have specific fertilization requirements. However, the soil can benefit from an annual application of a commercial balanced fertilizer. The best time to fertilize the plant is in late winter when it is still dormant. Be sure to follow the recommended dosage or manufacturer's instructions when applying the fertilizer. Over-fertilizing can lead to an unhealthy plant, and it could also cause damage to the nearby environment due to runoff.
Pruning
Eriogonum dendroideum does not require much pruning, but periodic trimming can help maintain a healthier and more aesthetically appealing shrub. Pruning should be done in the late winter or early spring before the blooming period. During this time, the plant is dormant, which reduces the amount of stress the plant will experience. Trim back dead or diseased branches using a pair of sharp pruning shears. You can also shear lightly the tips of the branches to encourage bushier growth.
Propagation of Eriogonum dendroideum
Eriogonum dendroideum, commonly known as mountain buckwheat or shrub buckwheat, is a shrubby perennial plant native to western North America. It is a popular plant for landscaping due to its attractive foliage and showy flowers. Propagation of Eriogonum dendroideum can be done through several methods.
Seed Propagation
The easiest and most common method of propagating Eriogonum dendroideum is through seeds. Seeds can be sown directly into the ground, or started indoors and transplanted. Seeds should be sown in well-drained soil in a sunny location. Germination can take up to 2-3 weeks, so be patient. Once the seedlings are several inches tall, they can be transplanted into their permanent location.
Cuttings Propagation
Another method of propagating Eriogonum dendroideum is through cuttings. Cuttings should be taken during the plant's active growth period, typically in late spring or early summer. The cuttings should be 4-6 inches long and taken from healthy, disease-free plants. Remove the lower leaves from the cuttings, and then dip the cuttings in rooting hormone. Once the cuttings have rooted, they can be transplanted into their permanent location.
Division Propagation
Division is a less common method of propagating Eriogonum dendroideum. It involves dividing the plant into smaller sections and replanting them. This method should only be done on mature plants that have become crowded. Carefully dig up the plant and gently separate the sections, making sure each section has a healthy root system. Replant the sections in their permanent location.
Overall, Eriogonum dendroideum is a hardy and easy-to-grow plant that can be propagated through several methods. With proper care, it can add beauty and interest to any landscape.
Disease Management
Eriogonum dendroideum is a relatively disease-resistant plant, but it can still be susceptible to some diseases if proper care is not taken. The following are some common diseases that may affect the plant:
- Phytophthora Root Rot: This soil-borne disease causes the roots to rot, which can lead to wilting, yellowing leaves, and eventual death of the plant. To manage this disease, ensure that the soil is well-draining and avoid overwatering the plant. Fungicides can also be used as a preventative measure.
- Crown Gall: This bacterial disease causes tumors to form at the base of the stem, which can lead to stunted growth or death of the plant. There is no cure for crown gall, so prevention is key. Ensure that the plant is healthy and stress-free, and avoid any mechanical damage to the stem.
- Rust: This fungal disease causes small, yellow or orange spots to appear on the leaves, which eventually turn brown and die. To manage rust, remove any affected leaves and dispose of them. Fungicides can also be used, but prevention through good plant hygiene is key.
Pest Management
Eriogonum dendroideum is relatively pest-resistant, but it can still be susceptible to some pests if proper care is not taken. The following are some common pests that may affect the plant:
- Aphids: These small insects can suck sap from the plant and cause stunted growth and yellowing leaves. To manage aphids, wash them off the plant with a strong stream of water or use insecticidal soap.
- Spider Mites: These tiny mites can cause yellowing and stippling of the leaves. To manage spider mites, ensure that the plant is well-watered and increase humidity around the plant. Insecticidal soap can also be used.
- Snails and Slugs: These mollusks can eat large holes in the leaves and flowers of the plant. To manage snails and slugs, handpick them off the plant and dispose of them. Copper barrier tape can also be used to prevent them from reaching the plant.
