white willow

White willow (Salix alba 'Tristis') should ideally be watered once or twice per week. The amount of water a white willow needs will depend on the season, soil type, and temperatures. During the summer months or when the temperatures are higher, the plant should be watered more frequently and generously. In the winter, you can reduce the amount of water to once a week. It is important not to overwater the plant as that can cause root rot. Use your finger to check the soil moisture level and only water if it feels dry. Make sure the soil drains well so that excess water can escape.

White willow (Salix alba 'Tristis') requires at least 4 to 5 hours of full, direct sunlight per day. The best time to provide that light is in the morning, when the sun is still e lower in the sky. This allows the sunshine to reach the plant in a less-intense state, so that it can gradually acclimate to the higher temperatures and light levels. Too much intense sun in the afternoon could scorch the leaves or cause heat stress to the plant, so it is best avoided unless the plant is acclimated to the harsher conditions.

White willow (Salix alba 'Tristis') should be pruned during the dormant season (the winter). Pruning for white willow should be done moderately in order to maintain the desired shape and density. Branches should be pruned directly above a dormant bud, angle cuts should be made to prevent water from sitting on the wound. Pruning should also be done to ensure good light penetration and air circulation. Finally, pruning should be done to promote higher numbers of flowers and catkins in the spring.
