Soil
Kelso willow prefers well-drained soils that are rich in nutrients. The plant can grow in a wide range of soils, including sandy, loamy, and clay soils. However, the soil must be moist but not waterlogged. The plant can tolerate a soil pH of 5.0 to 8.5. Adding organic matter to the soil can improve its fertility and texture.
Overall, providing sufficient sunlight, moderate temperature, and well-drained soil rich in nutrients is crucial for the successful cultivation of Salix dodgeana Rydb. var. subrariflora (L. Kelso) L. Kelso.
Cultivation of Salix dodgeana Rydb. var. subrariflora (L. Kelso) L. Kelso
Salix dodgeana Rydb. var. subrariflora (L. Kelso) L. Kelso is indigenous to North America and is best grown in a location that receives full sunlight. It grows well in USDA zones 4 to 9 and prefers well-drained soil that is slightly acidic to neutral.
Watering Needs
The amount of water your Salix dodgeana Rydb. var. subrariflora (L. Kelso) L. Kelso plant requires will depend on the growing environment. However, it prefers moist soil and can handle short periods of flooding, making it ideal for gardens that receive a lot of rainfall. Young plants require more water initially to establish their roots, but once fully grown, they require less water and can withstand periods of drought.
Fertilization
Salix dodgeana Rydb. var. subrariflora (L. Kelso) L. Kelso requires regular fertilization to enhance growth and development. Fertilize your plant with nitrogen-based fertilizers during the growing season, particularly in spring and early summer. Follow labelled instructions and avoid overfeeding your plant, as this may cause leaf burn or death.
Pruning
Pruning your Salix dodgeana Rydb. var. subrariflora (L. Kelso) L. Kelso plant is crucial to maintain its preferred shape and to encourage new growth. You should prune your plant during its dormancy period, particularly in late winter or early spring. Cut back any dead, damaged, or diseased branches to promote healthy growth. Additionally, you should remove suckers and unwanted branches to control the growth and spread of your plant.
Propagation of Salix dodgeana Rydb. var. subrariflora (L. Kelso) L. Kelso
The Salix dodgeana Rydb. var. subrariflora (L. Kelso) L. Kelso plant, commonly known as Kelso Creek willow, can be propagated by different methods depending on the availability of resources and desired outcomes. Here are some of the commonly used propagation methods:
Seed propagation
The plant's seeds can be sown in well-prepared beds or containers filled with a well-draining medium rich in organic matter. The seeds should be stratified for about three months at 1-5°C to provide the necessary conditions for dormancy breakage before sowing. The seeds should be covered with a light layer of soil and watered regularly to maintain moisture. Germination can occur within two weeks to three months depending on the seed's quality and conditions provided. Seedlings should be monitored and transplanted to their permanent location when they reach an appropriate size.
Cuttings propagation
Softwood stem cuttings of the plant can be taken during the growing season and treated with a rooting hormone to enhance the rooting process. The cuttings should be about 5 to 10 cm in length with at least two nodes. The leaves at the lower node should be removed to reduce water loss, and the cuttings planted in a well-drained rooting medium. The cuttings should then be covered and kept under high humidity and temperatures of between 20°C to 25°C. The rooting process can take about six weeks to three months, and the rooting success rates depend on the cuttings' quality and environmental conditions.
Division propagation
Clumps of the plant can be divided into smaller sections, each containing a rooted stem or shoot and several roots. The divisions should be done during dormancy in late winter or early spring, and the roots cut in a slanting manner to promote a larger surface area for water absorption. The sections should be planted in a well-draining soil mix and kept well watered until the new roots establish themselves. The success rate for division propagation is high as each section has a developed root system.
Disease and Pest Management for Salix dodgeana Rydb. var. subrariflora (L. Kelso) L. Kelso
Salix dodgeana Rydb. var. subrariflora (L. Kelso) L. Kelso, commonly known as Kelso shrub willow, is relatively resistant to pests and diseases. However, it may still fall victim to some common diseases and pests.
Diseases
One of the most common diseases affecting Salix dodgeana Rydb. var. subrariflora is willow blight, caused by the fungus Cryptosphaeria. It causes yellowing and browning of leaves, twig dieback, and cankers on stems. To manage willow blight, prune infected branches and remove them from the site. Additionally, avoid wetting the leaves by watering at the base and clean up fallen leaves from the ground.
Anthracnose can also affect Salix dodgeana Rydb. var. subrariflora, especially in wet conditions. It causes dead spots on leaves, and leaf drop. To manage anthracnose, avoid wetting leaves and remove infected debris.
Pests
One of the most common pests that attack Salix dodgeana Rydb. var. subrariflora is aphids. These small insects suck sap from leaves, causing them to curl and turn yellow. A strong blast of water or insecticidal soap can help to control aphid populations. Ladybugs and lacewings are natural predators of these pests and may help in controlling the population.
Another pest that may attack Salix dodgeana Rydb. var. subrariflora is spider mites. These small insects are hard to see, and they suck sap from leaves, which causes yellowing and often results in webbing that can be seen on the plant. To manage spider mites, keep the foliage moist through regular watering and use insecticidal soap or horticultural oil.
Overall, Salix dodgeana Rydb. var. subrariflora is relatively resistant to pests and diseases. However, proper cultural practices, such as avoiding overhead irrigation, cleaning up fallen leaves, and promoting good air circulation, are important for avoiding pest and disease problems.
