Light Requirements
The Salix lemmonii Bebb var. macrostachya Bebb requires full sun or partial shade to grow healthily. It can tolerate direct sunlight, but it prefers to be shaded or partially shaded during the hottest part of the day. It is best to plant this type of willow in an area that receives at least six hours of sunlight daily.
Temperature Requirements
The Salix lemmonii Bebb var. macrostachya Bebb is indigenous to arid regions and can withstand high temperatures. The ideal temperature range for the growth of this plant is 15°C to 35°C (59°F to 95°F). It can survive in temperatures as low as -12°C (10°F). However, if the temperature consistently drops below 0°C (32°F), this plant may suffer from frost damage or may die back to the ground but grow back in the spring.
Soil Requirements
The Salix lemmonii Bebb var. macrostachya Bebb prefers well-draining soil with a sandy or gravelly texture. It can grow in various soil types, including loam and clay, but requires a pH range of about 6.0 to 8.5. This plant can thrive in moist soil, but does not tolerate saturation. Proper drainage is critical to growing Salix lemmonii Bebb var. macrostachya Bebb. This species is also salt-tolerant and can grow in coastal areas with high salinity levels.
Cultivation Method
Salix lemmonii Bebb var. macrostachya Bebb, commonly known as Lemmon's willow, is native to North America and can be found in wet areas such as swamps, riversides, and marshes. When cultivating this plant, it is essential to choose a location with moist soil conditions that mimic its natural environment. The plant prefers full sun to partial shade, and it requires adequate space since it grows to be approximately 8 to 30 feet tall.
Watering Needs
Salix lemmonii Bebb var. macrostachya Bebb requires frequent watering to maintain moist soil conditions. During the hot and summer months, the plant may need to be watered daily. However, during the winter months, watering can be reduced. Do not allow the soil to dry out entirely, as the plant will show signs of stress and may become susceptible to pests and diseases.
Fertilization
Lemmon's willow does not typically require excessive fertilization. The plant can benefit from an all-purpose fertilizer once a year, typically in the spring, to give it an extra boost. Over-fertilizing can be detrimental to the plant and cause it to grow excessively, leading to weak stems and branches.
Pruning
Salix lemmonii Bebb var. macrostachya Bebb typically requires minimal pruning except for removing damaged, dead, or diseased branches. It is advisable to undertake any necessary pruning during the plant's dormant season, typically in late winter or early spring. Pruning can also be used to maintain a desired shape and size.
Propagation of Salix lemmonii Bebb var. macrostachya Bebb
Salix lemmonii Bebb var. macrostachya Bebb, commonly known as Lemmon's willow, is a species of willow tree that is native to the western United States. Propagation of this plant is done mainly through two methods, namely seed propagation and vegetative propagation.
Seed propagation
Seed propagation involves collecting seeds from a mature willow tree during the fall or early winter. These seeds should be stored in a cool, dry place until it is time to sow them. In the spring, when the soil has warmed sufficiently, the seeds can be sown in a well-draining soil mix and covered lightly with soil. Water the seed tray regularly, and the seeds should germinate within two weeks. Thin out the seedlings once they reach a height of 2-3 inches.
Vegetative propagation
Vegetative propagation of Salix lemmonii Bebb var. macrostachya Bebb is achieved through stem cuttings. The best time to take cuttings is during the late winter or early spring when the growth of the plant is dormant. Take cuttings that are about 6-8 inches long with several nodes. Remove the bottom leaves from the cutting, leaving only two or three leaves at the top. Dip the cut end of the stem into rooting hormone powder and plant it in a well-draining soil mix. Cover the cutting with a clear plastic bag to increase humidity levels, and place it in a bright area with indirect sunlight. In about four weeks, roots will start to grow, and the plant can be transferred to a larger pot or planted outdoors in suitable conditions.
Diseases
Salix lemmonii Bebb var. macrostachya Bebb is prone to fungal diseases like willow scab and canker diseases. It can also be affected by viral diseases like willow mosaic virus and bacterial diseases like willow blight.
To manage these diseases, it is essential to keep the plant healthy by providing it with the proper environmental conditions and appropriate care. Prune the plant and cut off any infected parts immediately. Dispose of the infected plant material properly to prevent the spread of the disease. Use fungicides, pesticides, or bactericides if required. Ensure to follow the instructions provided on the product label for safe and effective use.
Pests
The plant can be affected by several pests like aphids, scale insects, willow sawfly, and caterpillars of various moths. These pests feed on the plant's leaves, stems, and buds, leading to stunted growth and reduced plant health.
To manage these pests, inspect the plant frequently and remove any visible pests by hand. Use insecticides if required, following the instructions provided on the product label. Encourage natural predators like ladybugs and lacewings to control the pest population naturally. Additionally, maintain plant health by providing adequate irrigation and fertilization to prevent pest infestations.
