Light Requirements
Salix lasiolepis Benth. var. bigelovii prefers full sun to partial shade for optimal growth and development. It can tolerate shade, but this will result in slower growth and weaker plants with fewer flowers and fruits. In shady conditions, the plant tends to stretch towards the light, causing a lanky growth habit that can be unsightly.
Temperature Requirements
This plant is adapted to a wide range of temperature zones, from hot desert regions to coastal areas with mild temperatures. It can tolerate temperatures from -29 to 41 °C (-20 to 105.8°F). However, the ideal temperature range for growth and fruiting is between 13 to 27°C (55.4 to 80.6°F).
Soil Requirements
Salix lasiolepis Benth. var. bigelovii grows well in a variety of soil types, from sandy loams to heavy clays. The ideal soil pH range is between 5.0 to 8.0, with a preferred pH of 6.0 to 7.5. The soil must be well-drained, as this plant does not tolerate waterlogged conditions. It has moderate drought tolerance and can withstand periodic flooding.
Cultivation of Salix lasiolepis Benth. var. bigelovii (Torr.) Bebb
Salix lasiolepis Benth. var. bigelovii (Torr.) Bebb, commonly known as Bigelow's willow, is native to the southwestern United States. It is a hardy plant that can tolerate a range of temperature and soil conditions, making it a popular choice for landscaping and erosion control.
The plant can be propagated from cuttings or seeds, and it prefers well-drained soil with good moisture retention. It is a fast-growing plant that requires ample space to grow, so it should be planted at least 20-30 feet apart from other plants or structures.
Watering Needs of Salix lasiolepis Benth. var. bigelovii (Torr.) Bebb
Salix lasiolepis Benth. var. bigelovii (Torr.) Bebb requires regular watering, especially during the growing season. The soil should be kept moist but not waterlogged, as excessive watering may lead to root rot. Watering should be reduced during the winter season to avoid waterlogging and freezing of roots.
Mulching the soil around the plant can also help in retaining moisture and preventing evaporation during hot weather.
Fertilization of Salix lasiolepis Benth. var. bigelovii (Torr.) Bebb
Salix lasiolepis Benth. var. bigelovii (Torr.) Bebb requires regular fertilization to maintain healthy growth and foliage. A balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium should be applied during the growing season.
Organic fertilizers such as compost and manure can also be applied around the plant to improve soil fertility and nutrient availability.
Pruning of Salix lasiolepis Benth. var. bigelovii (Torr.) Bebb
Salix lasiolepis Benth. var. bigelovii (Torr.) Bebb requires regular pruning to maintain its shape and size. Pruning should be done during the winter season when the plant is dormant.
The plant should be pruned to remove dead or damaged branches, and to thin out the branches to improve airflow and sunlight penetration. The plant should not be pruned too severely, as this may lead to stunted growth and reduced foliage.
Propagation of Salix lasiolepis Benth. var. bigelovii (Torr.) Bebb
Salix lasiolepis Benth. var. bigelovii (Torr.) Bebb, also known as Bigelow's sagebrush willow, is a deciduous shrub native to North America. It can be propagated through several methods:
Seed Propagation
Seeds can be collected from the plant in the fall, stored in a cool, dry place, and sowed in the spring. The seeds should be planted in a seedbed that is moist and well-drained, with a soil depth of about ½ inch. Germination typically occurs within two weeks, and the seedlings can be transplanted to their permanent location once they are about 6 inches tall.
Cuttings Propagation
Softwood cuttings should be taken from the plant in the summer, when the stems are still green and pliable. Cuttings should be about 6 inches long, with a 45-degree angle cut at the base. Remove all leaves from the cutting except for the top few. Dip the cut end of the cutting into rooting hormone and plant it in a container with well-draining soil. Keep the soil moist and the container in a warm, bright location. Roots should form within 2-4 weeks, and the plant can be transplanted once the roots are established.
Layering Propagation
Layering is another method of propagation that involves bending a flexible stem from the parent plant down to the soil and burying a section of the stem. After a few weeks, roots should form where the stem is in contact with the soil. The stem can then be cut from the parent plant and transplanted to its permanent location.
Disease management
Salix lasiolepis Benth. var. bigelovii (Torr.) Bebb is susceptible to a few diseases that can harm the plant and weaken its growth. Some of the common diseases that may infect the plant are:
- Canker: It is a fungal disease that causes the bark to crack and cankerous lesions to form. The infected plant parts should be removed and destroyed, and the plant should be treated with a fungicide.
- Rust: It is a fungal disease that can cause yellowish-orange spots on the leaves and stems. The infected plant parts should be removed and destroyed, and the plant should be treated with a fungicide.
- Mildew: It is a fungal disease that can cause a white powdery substance to develop on the leaves. The infected plant parts should be removed and destroyed, and the plant should be treated with a fungicide.
To prevent the spread of diseases, it is important to keep the surrounding area clean and remove any infected parts as soon as they are noticed. Using disease-resistant varieties and ensuring proper irrigation and drainage can also reduce the risk of disease infections.
Pest management
Salix lasiolepis Benth. var. bigelovii (Torr.) Bebb can also fall prey to some pests which can damage the plant and reduce its productivity. Some of the common pests that may harm the plant are:
- Aphids: They are small, soft-bodied insects that suck sap from the leaves and shoot tips, causing stunted growth and deformation of shoots. The pests can be controlled by pruning infected parts and using insecticidal soaps or neem oil.
- Caterpillars: They are the larvae of moths or butterflies that feed on the leaves and can cause defoliation. The pests can be controlled by handpicking or using organic insecticides.
- Scales: They are insects that feed on the sap of the leaves and stems, causing yellowing and drop off of leaves. The pests can be controlled by using horticultural oils or insecticidal soaps.
Preventive measures include maintaining proper hygiene, avoiding over-fertilization, and using biological control agents like ladybugs and lacewings. Regular monitoring and early detection of pest infestation can help in controlling the spread and preventing damage to the plant.
