e Pebbles or crushed rock make an attractive mulch and doesn't attract rodents the way organic mulch can. With a combination of rocks and a barrier layer (such as three-four sheets of newspapers, four mil black plastic or one of the new weed barrier fabrics) underneath, weed control is assured for up to two years. Use impermeable barrier lavers (solid plastic) in situations where no plant growth is desired. Around shrubs or trees use a permeable weed barrier (landscape fabric) which allows air and water to reach the roots of desirable plants.
t Pine needles are like good building insulation — full of air spaces. They insulate the soil and make an ideal winter mulch for perennial flowers, small fruit plants (especially strawberries) and acid-loving shrubs and trees. Pine needles prevent alternate freezing and thawing which may leave shallow-rooted plants out of the ground, a problem especially serious on heavy soils.
