It can tolerate temperatures as low as -40 degrees Celsius and as high as 25 degrees Celsius. However, it prefers average temperatures between 10 to 15 degrees Celsius.
Soil Requirements
The plant Salix fulcrata Anderss. var. subglauca Anderss. prefers moist, well-drained soils that are rich in nutrients. It can grow in a variety of soil types but performs best in loamy soils that are slightly acidic with a pH range of 6.0 to 7.5. It is tolerant to periodic flooding and soil compaction but does not tolerate water-logged soil conditions.
Cultivation Methods
The Salix fulcrata Anderss. var. subglauca Anderss. plant is best grown in soil that is moist and well-draining. It is important that the soil has good drainage because the plant does not tolerate waterlogged soil. The plant should receive at least six hours of sunlight every day and can tolerate some shade. It is recommended to plant the Salix fulcrata Anderss. var. subglauca Anderss. plant in the spring or fall when the weather is cool.
Watering Needs
The Salix fulcrata Anderss. var. subglauca Anderss. plant requires regular watering during the growing season. The soil should be kept moist, but not waterlogged. Overwatering can cause the roots to rot, so it is important to ensure adequate drainage. During the winter months, the plant should be watered less frequently as it enters a state of dormancy.
Fertilization
The Salix fulcrata Anderss. var. subglauca Anderss. plant is a heavy feeder and requires regular fertilization. It is recommended to fertilize the plant once every two weeks during the growing season with a balanced fertilizer. The fertilizer should be applied according to the manufacturer's instructions. During the winter months, fertilization should be reduced or stopped completely.
Pruning
The Salix fulcrata Anderss. var. subglauca Anderss. plant requires regular pruning to maintain its shape and promote healthy growth. Pruning should be done in the late winter or early spring, before new growth begins. Dead or damaged branches should be removed, and any branches that are crossing or rubbing against each other should be pruned back. The plant can also be pruned to control its size, but care should be taken not to remove too many branches at once as this can weaken the plant.
Propagation of Salix fulcrata Anderss. var. subglauca Anderss.
Salix fulcrata Anderss. var. subglauca Anderss., commonly known as the Shrub Willow, is propagated mainly through seeds and cuttings. Both these methods provide reliable results and are widely used by gardeners and plant enthusiasts alike.
Seed Propagation
The seeds of Salix fulcrata Anderss. var. subglauca Anderss. are collected from mature plants in the fall when they are ripe. The seeds are then dried and stored in a cool and dry place until spring when they are ready to be sown. To increase the germination rate of the seeds, they can be stratified for four to six weeks before planting. For this, the seeds are kept in a moist medium at a temperature of around 1-5°C. The stratified seeds are then planted in a well-draining potting mix and kept moist until they germinate. Once the seedlings have 2-3 sets of true leaves, they can be transplanted into their final containers or in a garden bed.
Cutting Propagation
Cutting propagation of Salix fulcrata Anderss. var. subglauca Anderss. is also a reliable method. The cuttings are taken from healthy mother plants in early spring when new growth is emerging. The cuttings should be around 6-8 inches long and taken from non-flowering shoots. The bottom half of the leaves is removed, and the cutting is dipped in a rooting hormone before inserting it into a well-draining potting mix. The cutting is then placed in a humid environment, and the soil should be kept moist until it roots. Once the cutting has rooted, it can be transplanted into its final container or in a garden bed.
Disease Management
Salix fulcrata Anderss. var. subglauca Anderss. can be prone to various diseases, including:
- Rust: This fungal disease can cause yellow-orange spots on leaves and stems. To manage rust, remove and destroy infected plant material, promote good air circulation, and properly water the plant. Fungicides can also be used in severe cases.
- Leaf spot: This fungal disease causes brown or black spots on leaves. To manage leaf spot, remove and destroy infected plant material, avoid overhead watering, and promote good air circulation. Fungicides can also be used in severe cases.
- Canker: This bacterial disease causes sunken, dark areas on branches or trunks. To manage canker, prune infected branches at least 6 inches below the diseased area and destroy the infected material. Sanitize pruners between cuts and avoid wounding the plant. Copper fungicides can also be used preventatively.
Pest Management
Salix fulcrata Anderss. var. subglauca Anderss. may also be vulnerable to pests, including:
- Aphids: These tiny insects can cause distorted growth and yellowing leaves. To manage aphids, spray the plant with a strong jet of water or spray with insecticidal soap. Avoid using broad-spectrum insecticides which can harm beneficial insects.
- Willow leaf beetle: These beetles can skeletonize leaves, causing them to turn brown and fall off. To manage willow leaf beetles, remove and destroy heavily infested leaves, encourage natural predators like birds and beneficial insects, and use insecticides as a last resort.
- Scales: These insects attach themselves to the leaves or stems and suck sap. Infested plants may have yellow or wilted foliage. To manage scales, scrape them off the plant with a plastic card or use insecticidal soap. Neem oil can also be used as a preventative.
