QuestionsHow to growTrees and ShrubsPlantingwillow 0 Vote Up Vote Down tom d asked 13 years ago I recently planted some bare root willow slips to form a screen/hedge. I planted about 3ft apart. Can you give any advice on getting them going good? Can I put lawn cuttings around and between the willow?

Control grass and weeds and grass mowings can help to control weeds, but tend to release grass seeds when broken down.
