Soil & Fertilizer

The best soil for pink willow tree is well-drained, moist and rich in organic materials. When trying to grow Japanese willow in arid climates, provide a layer of mulch around it to prevent evaporation. Ensure the stem does not touch organic mulch to prevent diseases.

Pink willow trees are quick growers and usually do not need any fertilizer. If you cannot be persuaded otherwise, for a young tree feed it a tablespoon of granulated slow-release fertilizer (10-10-10) annually and water it after. Next year you can feed it two tablespoons and for a mature plant four tablespoons.
