Tree King waterbag

The Treeking water bag is a flat, partially closed bag with a zipper on both sides. The bag is folded around the trunk of the tree and fastened with the zipper. When the bag is 1/4 full, lift it up slightly to straighten the bag and fill it completely with water.

You can mix fertilizer into the water so that the tree can gradually absorb it. Use liquid fertilizers or make sure you completely dissolve the fertilizer before it enters the water bag.
