Willow tree water in winter
How often do you water a young willow tree in the winter?
If your Willow is a new planting, you should give it daily water for the first 2 weeks.
Then you can cut back. If the tree is completely dormant (no leaves) you can give it occasional water.
If the Willow is leafed out you will want to likely water once a week or when the soil is dry 6 to 8 inches down.
Adding 2 to 3 inches of hardwood mulch will help with moisture retention.
