Rain, melting ice, and wind make gardens—especially those situated on an incline—susceptible to erosion. Some easy-to-spot indicators of erosion include exposed roots, muddy puddles, or soil "downstream" from the garden, whether on the sidewalk or the lawn. If you see any of these warning signs, your plot may be at risk of destruction. Protecting your plant beds is as easy as adding mulch, which helps stabilize the soil. Choose a heavier hardwood or manmade mulch that won't blow away easily, so your garden will stay perfectly in tact.
