[title] Use bark, shredded wood or wood chips to prevent weed growth. Ending2: [title] Mix mulch and pine-ash compost in a garden pot with small rocks.

[substeps] If you choose to use old dirt as your mulch, create a stable layer around the base of the tree to store your mulch granules. Ending4: [title] Plant organic mulches around ponds and streams.
