Light Requirements
The Salix rotundifolia Trautv. var. dodgeana (Rydb.) E. Murr. plant requires moderate to full sunlight exposure. It can tolerate partial shade, but excessive shade can cause stunted growth and foliage thinning. Therefore, it is best to plant this species in an open area where it can receive adequate sunlight throughout the day.
Temperature Requirements
This plant species can grow in a wide range of temperatures. However, it prefers cool summers and mild winters. In general, the average temperature range of 21-27°C (70-80°F) during the growing season is ideal for its growth. In winter, the temperature should be preferably below freezing. This plant species has a high tolerance for cold weather and can withstand temperatures as low as -50°C (-58°F).
Soil Requirements
Salix rotundifolia Trautv. var. dodgeana (Rydb.) E. Murr. plants grow well in moist, well-drained soils that are rich in organic matter. The soil pH should range between 6.0 to 7.5 for best growth. Additionally, this plant species needs soil that is rich in nutrients, particularly nitrogen, phosphorus, and potassium. The soil should also be adequately aerated to promote root growth and efficient water and nutrient uptake. It is recommended to plant this species in a loamy soil type with good drainage characteristics.
Cultivation methods
The Salix rotundifolia Trautv. var. dodgeana (Rydb.) E. Murr. plant is a resilient species that thrives well in various climatic conditions. The plant prefers soil that is rich in minerals and well-draining. To cultivate this plant, one must prepare the planting site by removing any rocks, weeds, or debris. Afterward, dig a hole that is twice the size of the root ball and add organic matter to the soil. This will provide the necessary nutrients for the plant to thrive.
Watering needs
Proper watering is essential for the growth and development of the Salix rotundifolia Trautv. var. dodgeana (Rydb.) E. Murr. plant. The plant requires regular watering during the growing season, especially in hot and dry weather. However, it is recommended that growers allow the soil to dry up completely before watering the plant again. This prevents the roots from rotting due to excessive moisture. Overwatering can be detrimental to the plant's health, especially during the winter season.
Fertilization
The Salix rotundifolia Trautv. var. dodgeana (Rydb.) E. Murr. plant requires regular fertilization to promote healthy growth and development. It is recommended that growers use a slow-release fertilizer to ensure that the plant receives a steady supply of nutrients. Fertilizer should be applied during the growing season, preferably in spring and summer. Over-fertilization can cause damage to the plant, so it is essential to follow the manufacturer's instructions.
Pruning
Pruning is important to maintain the Salix rotundifolia Trautv. var. dodgeana (Rydb.) E. Murr. plant's shape and promote healthy growth. Growers should prune the plant during the dormant season to remove dead or damaged branches and promote new growth. It is recommended that only one-third of the plant be pruned at any given time. This allows the plant to recover without disrupting its growth. Regular pruning prevents the plant from becoming overgrown and improves its appearance.
Propagation of Salix rotundifolia Trautv. var. dodgeana (Rydb.) E. Murr.
Salix rotundifolia Trautv. var. dodgeana (Rydb.) E. Murr. can be propagated in a number of ways. Some of the most common methods are:
Propagation from cuttings
The best time to take cuttings is in early spring, just before the plant starts to leaf out. Cuttings should be taken from young, healthy shoots and should have at least two nodes. The cuttings should be about 6 to 8 inches long and should be dipped in rooting hormone before being planted in a well-draining potting mix. They should be kept moist and in a warm, humid environment until they start to root. Once the roots are well-established, the cuttings can be transplanted into larger containers or directly into the garden.
Propagation from seed
Propagation from seed is also an option, although it is not as common as propagation from cuttings. The seeds should be stratified before planting, which means they should be placed in a moist, cool environment for several weeks to break their dormancy. Once they have been stratified, the seeds can be planted in a well-draining potting mix and kept moist. They should be kept in a warm, bright location until they sprout, and then gradually acclimatized to more sun and less humidity.
Propagation in water
Propagation in water is another option for Salix rotundifolia Trautv. var. dodgeana (Rydb.) E. Murr. Cuttings can be taken and placed in a jar of water, with the lower nodes submerged. Once roots have developed, the cuttings can be transplanted into soil.
Disease Management
Salix rotundifolia Trautv. var. dodgeana (Rydb.) E. Murr. is susceptible to several diseases that can cause significant damage to the plant. The following are some of the common diseases that affect this plant:
- Bacterial blight: This disease is caused by the bacterium Pseudomonas syringae and can cause leaf spots, twig dieback, and cankers on the plant. To manage this disease, it is important to prune and destroy infected branches and avoid overhead watering, which can spread the bacteria.
- Cytospora canker: This fungal disease can cause cankers on the bark and branches of the plant, leading to wilting and eventual death. To manage this disease, prune and destroy infected branches and apply fungicides to the remaining ones.
- Willow scab: This fungal disease can cause leaf spots, defoliation, and cankers on the plant. To manage this disease, prune and destroy infected branches and apply fungicides to the remaining ones.
Pest Management
Salix rotundifolia Trautv. var. dodgeana (Rydb.) E. Murr. is also susceptible to pests that can cause significant damage to the plant. The following are some of the common pests that affect this plant:
- Aphids: These tiny insects can cause wilting and distortion of the leaves. To manage aphids, introduce natural predators such as ladybugs or apply insecticidal soap.
- Scale insects: These insects can cause yellowing and wilting of the leaves. To manage scale insects, apply insecticidal soap or horticultural oil to suffocate them.
- Caterpillars: These larvae can cause defoliation of the plant. To manage caterpillars, handpick them off the plant and introduce natural predators or apply Bacillus thuringiensis (Bt).
