What to do in your garden in November; control moss and algae - Northern California

Sunset, Nov, 2003

Brick, concrete, and other paved surfaces in moist, shady areas are often susceptible to moss or algae growth, which can be very slippery. The best cure is prevention; Improve air circulation and light above the paved surface by pruning up overhanging branches. If moss or algae is already established, rent a pressure washer from an equipment rental yard and blast off the growth. Or apply an environmentally safe product (such as Safer Moss & Algae Killer & Surface Cleaner, $15; available from garden centers or Biocontrol Network, www.biconet.com or 800/441-2847) to eliminate the problem.--L.B.S.
