Light Requirements
Salix tristis Ait. var. microphylla Anderss. requires full sun exposure for optimal growth. The plant thrives in areas with high light intensity and can withstand direct sunlight. Therefore, it's essential to plant this variety of willow in an area that receives direct sunlight for at least 6-8 hours daily.
Temperature Requirements
The plant thrives in moderate to cool temperature ranges and can withstand extreme cold conditions. The ideal temperature range for Salix tristis Ait. var. microphylla Anderss. is between 7-27 degrees Celsius. The plant prefers cool nights over hot ones and can also tolerate heat stress by shedding its leaves to conserve water.
Soil Requirements
The plant can grow in both fertile and infertile soils but prefers well-drained, moist soils rich in organic matter. Salix tristis Ait. var. microphylla Anderss. grows best in soils with a pH range of 5.6 to 7.5. Alkaline soils may inhibit its growth, but the plant can still survive in such conditions. Therefore, it's advisable to plant it in humus-rich soils that hold moisture well.
Cultivation Methods
Salix tristis Ait. var. microphylla Anderss. is a hardy plant that grows well in various soil types, including sandy, loamy, or clay soils. It is vital to plant this species in an area with a sufficient drainage system to prevent waterlogging. The best time to plant Salix tristis Ait. var. microphylla Anderss. is during the dormant season, which is in early spring or late fall. If you live in an area that experiences extreme weather conditions, consider planting it in a sheltered area to protect it from the elements.
Watering Needs
Salix tristis Ait. var. microphylla Anderss. requires frequent watering to support healthy growth. It is best to provide it with water immediately after planting and keep the soil moist, but not waterlogged. During the growing season, you should water your plant deeply every seven to ten days. However, if the weather is hot and dry, you may need to water it more often. Avoid watering the foliage and concentrate on the soil around the plant's base.
Fertilization
Salix tristis Ait. var. microphylla Anderss. benefits from regular fertilization to thrive. You should apply a slow-release fertilizer in early spring, just before new growth begins. Additionally, you should provide your plant with a nitrogen-rich fertilizer in the summer to support vigorous growth. However, avoid fertilizing your plant in the fall, as it may lead to new growth that will be susceptible to frost damage.
Pruning
Pruning Salix tristis Ait. var. microphylla Anderss. is essential to promote healthy growth and maintain its aesthetic appeal. You should prune your plant during the dormant season to encourage vigorous growth during the following season. Remove any dead or diseased branches to prevent the spread of disease, and thin out overgrown areas to encourage air circulation. Additionally, shaping your plant through pruning will promote a dense, bushy growth habit.
Propagation methods of Salix tristis Ait. var. microphylla Anderss.
Salix tristis Ait. var. microphylla Anderss. can be propagated through various methods:
Seed propagation
The seeds of Salix tristis Ait. var. microphylla Anderss. can be collected from mature plants. The seeds need to be sown immediately as they have a short viability period.

Cutting propagation
Cuttings of Salix tristis Ait. var. microphylla Anderss. can be taken in the early spring before the growth starts or in the late autumn after the growth has stopped. The cuttings should be taken from one-year-old branches and should be approximately 15-20 cm long. The cuttings should be treated with rooting hormones and should be planted in a well-draining soil mix. The soil should be kept moist until the cuttings have developed roots and started to grow actively.
Grafting propagation
Grafting is a method used to propagate Salix tristis Ait. var. microphylla Anderss. onto a rootstock. The rootstock should be compatible with the Salix tristis Ait. var. microphylla Anderss. scion. This method can be used to propagate cultivars or to improve the root system. The grafting can be done in the early spring or autumn.
Overall, Salix tristis Ait. var. microphylla Anderss. is a relatively easy plant to propagate, with multiple methods available to choose from.
