How to Care for a Dwarf Indoor Willow Tree

Put the dwarf willow tree in a location near a glass door or windows. This tree grows best in full or partial sunny areas outside, so find a spot indoors with at least a few hours of bright sunlight. Choose south- or west-facing windows for the most sunlight.

Water the willow tree until you see water drain from the bottom, but never leave the water in the tray. Wait until the soil dries an inch or so down before watering the tree again. Water the tree less often during the winter, while the tree is naturally dormant.

Apply an all-purpose fertilizer, such as 10-10-10, as directed on the label while the willow tree is actively growing from spring to fall. Another option to enrich the soil is to replace the top few inches of soil in the container with fresh soil each spring.

Prune the dwarf willow tree during the winter as needed to maintain the shape and to get rid of any frail or damaged branches.

Repot the willow tree when it outgrows its container. Use top-quality potting soil and a container that is one size bigger. Always replant the dwarf willow at the same depth in the soil as previously grown.

Check the willow tree often for any signs of pests or diseases. Look for changes in the color, shape or texture of all parts of the tree. Identify and treat any problem found as soon as possible.
