Mulch, mulch, mulch! Tree grindings, leaves, wood chips, shredded bark, grass clippings, compost, and manure are all common mulches. Spread mulch at least a couple of inches deep around your new plants (but keep the mulch a couple of inches from the plants stem). Use mulch over weed barriers (cardboard or newspaper) if youre eager to reduce weeding. Weed barriers are temporary, though; annual additions of mulch and crowding by plants helps control weeds and creates a healthy landscape in the long run.

The general rule is use woody mulches, such as wood chips, bark or tree grindings, around woody plants. Around perennials and annuals, a better choice would be compost, manure or leaves.
