Proper Watering and Fertilization
Weeping willows require sufficient water, and that’s the reason it’s ideal to grow near ponds or lakes. If grown in the garden, water the plant, especially during the dry period. The younger trees need more fertilization compared to the already grown plants. Use balanced fertilizer in early spring to ensure healthy growth of the plant.
Regular Pruning
Pruning is essential to maintain the tree's shape and remove dead and damaged branches. Branches become too heavy and split if pruning is not done regularly.
