Light Requirements
Arctostaphylos tomentosa (Pursh) Lindl. var. trichoclada (DC.) Munz is a plant that prefers full sunlight. It can tolerate partial shade, but it will grow and thrive best when exposed to the direct sunlight for at least six hours each day.
Temperature Requirements
The plant is native to the coastal regions of California and prefers mild temperatures. It grows best in regions with a Mediterranean climate with mild winters and hot, dry summers. The plant can tolerate temperatures as low as 20°F (-6°C) and as high as 100°F (38°C). However, it will not grow well in regions with extreme temperature fluctuations.
Soil Requirements
Arctostaphylos tomentosa (Pursh) Lindl. var. trichoclada (DC.) Munz thrives in well-drained soils that are slightly acidic. The plant can grow in a wide range of soil types, including sandy, loamy, and clay soils, as long as there is good drainage. The plant does not tolerate waterlogged soil and will quickly die if left in standing water. The plant's roots are sensitive to disturbance, so it is essential to avoid planting it in soil that has been compacted or heavily disturbed.
Cultivation methods
The Arctostaphylos tomentosa (Pursh) Lindl. var. trichoclada (DC.) Munz, commonly known as the hairy manzanita, is a drought-tolerant evergreen shrub native to California. To cultivate this plant, it is necessary to provide well-draining soil to avoid root rot. The ideal planting location is an area with full sun or partial shade. Young plants should be protected from direct sunlight and frost to encourage healthy growth.
Propagation can be done through seeds or cuttings. If using cuttings, it is best to select young, tender stems in the spring and summer months. The stem cuttings should be around four inches long, and the leaves on the lower part of the stem should be removed. The cuttings should be planted in a mixture of peat moss and perlite or vermiculite. The soil should be kept moist until the roots develop.
Watering needs
The hairy manzanita is a drought-tolerant plant and does not require frequent watering. During the growing season, the plant can go for several weeks without water, but it is best to water the plant when the top layer of soil is dry. Overwatering can cause root rot and potentially kill the plant. It is essential to avoid getting water on the foliage to prevent fungal diseases.
Fertilization
The hairy manzanita does not require frequent fertilization. It is best to avoid using chemical fertilizers and instead opt for organic alternatives, such as compost or aged manure. Fertilization can be done once a year after the seedlings' first growing season, typically in the spring or fall.
Pruning
Pruning is an essential aspect of caring for the hairy manzanita, as it helps encourage healthy growth and maintains the plant's shape. It is best to prune the plant during the winter months when it is dormant. Dead and damaged branches should be removed, and the plant should be thinned to promote air circulation and reduce the risk of disease. It is best to avoid severe pruning, as this can cause stress to the plant and inhibit growth.
Propagation of Arctostaphylos tomentosa var. trichoclada
Arctostaphylos tomentosa var. trichoclada, commonly known as Eastwood's manzanita, is a shrub species that is native to California. It is commonly used for landscaping and erosion control in gardens because of its ornamental value and ability to thrive in dry conditions. Propagation of this plant involves several methods that are suitable for both home gardeners and commercial growers.
Seed Propagation
Seed propagation is the primary method of Arctostaphylos tomentosa var. trichoclada propagation. Seeds can be collected from the fruit that ripens from August to October. The seeds need to be stored in a refrigerator at 40°F for at least 60 days before sowing. The best time for seed sowing is late winter or early spring in a soil mixture of peat moss, sand, and perlite. Cover the seeds with a fine layer of soil or sand, and keep the soil moist. After about one month, the seeds will sprout, and the seedlings can be transplanted to their permanent location after the last frost.
Cuttings Propagation
Arctostaphylos tomentosa var. trichoclada can also be propagated from stem cuttings taken in late summer or early fall. Select a young stem without flowers or fruit, and cut a 6-inch section of the stem. Then, remove the lower leaves of the cutting, leaving only two to four leaves at the top. Dip the stem end in rooting hormone powder and plant it firmly in moistened soil mixture. Keep the soil moist and the cutting in a shady location. The rooting process can take a few weeks to several months, depending on temperature and humidity. Once roots have formed, transplant the cutting to its permanent location.
Layering Propagation
Another effective method of propagation for Arctostaphylos tomentosa var. trichoclada is layering. Layering is done by bending a low-growing branch of the plant down to the soil and covering it lightly with soil. The stem should be notched slightly, treated with rooting hormone, and held in place with a U-shaped wire. The layered stem will root in a few months, and the new plant can be separated from the parent plant and transplanted when it has developed extensive roots.

This plant is native to California and is often found in chaparral and woodlands. Like any other plant species, it is susceptible to various diseases and pests. Here are some common diseases and pests that might affect Arctostaphylos tomentosa and ways to manage them:
Diseases
Phytophthora root rot: This disease is caused by Phytophthora cinnamomi and is a common problem for Arctostaphylos tomentosa. Symptoms of this disease include yellowing leaves, wilting, and plant death. To prevent the spread of this disease, avoid planting in areas with poor drainage and provide good soil drainage by using raised beds or adding organic matter to the soil. Avoid over-irrigation and prevent the introduction of the pathogen to new areas by using sterilized soil and planting materials.
Anthracnose: This disease is caused by Colletotrichum gloeosporioides and is characterized by brown or black spots on the leaves and stems of the plant. Infected plant parts can become distorted, and in severe cases, defoliation may occur. To manage this disease, remove and destroy infected plant parts immediately, practice good sanitation by removing debris from the planting area, and apply fungicides as recommended.
Pests
Spider mites: Spider mites are tiny pests that feed on the sap of the plant's leaves, resulting in yellowing and bronzing of the leaves. They also produce webbing that can cover the entire plant. To manage spider mites, increase the humidity around the plants, use a strong jet of water to dislodge the pests from the leaves, and apply insecticides as recommended.
Scale insects: These pests are common on Arctostaphylos tomentosa and are characterized by small, oval-shaped bumps on the leaves and stems. They feed on the sap of the plant, causing wilting and yellowing of the leaves. To manage scale insects, prune heavily infested branches, and apply insecticidal soaps or horticultural oils as recommended.
By staying vigilant and taking proactive measures to prevent and manage diseases and pests, you can keep your Arctostaphylos tomentosa (Pursh) Lindl. var. trichoclada (DC.) Munz plant healthy and thriving.
