Low-maintenance perennial garden
Landscape fabric discourages weeds
When you start a new perennial border, spread non-woven polypropylene black landscape fabric over the soil. The fabric keeps weeds under control, holds heat in cool spring weather (giving your plants a faster start), and lets water soak through to the roots. At a local garden center, buy a nonbiodegradable fabric that weighs about 3.4 ozs. per square yard (about $10 for a 3 x 25-ft. piece). Use U-shaped metal stakes ($2 for a pack of 10) to hold down the fabric.
