Do the dwarf willow tree have to be pruned when the branches are touching the ground?

Yes, dwarf willow trees may need to be pruned when their branches touch the ground to maintain their shape and promote healthy growth. Pruning can prevent the branches from becoming damaged or promoting rot by making contact with the soil. Regular maintenance helps improve air circulation and light penetration, which can enhance the tree's overall health. However, the extent of pruning should be considered based on the specific growth habits of the tree and the desired aesthetic.
