Tips on yard care, water savings
Think twice before using pesticides.
Scientists have found 23 pesticides (weed and bug killers) in our local streams, many at levels that may damage salmon and other wildlife. Overuse of these products can also damage soil and plant health. Studies have found increased health risks among families that use lawn and garden pesticides, especially among pets and children. The good news is that we really don’t need most of those chemicals.
Most bugs are good bugs. Only about 5% of the bugs in your yard are pests. “Good bugs” like the ground beetle and the green lacewing help control pests.
Start with prevention.
SBltBuild healthy soil with compost and mulch – soil organisms protect plants from many disease and insect pest problems.
SBltSelect pest-resistance plants, and put them in the sun/shade and soil conditions they like.
SBltClean up diseased plants, and compost dead plants in fall to reduce hiding places for insect pests.
SBltPull weeds before they go to seed and spread.
SBltUse a variety of plants, so if pests attack one plant, others can fill its place.
Identify the problem before you spray, squash, or stomp.
The problem could really be incorrect mowing or pruning, improper watering, or other easily corrected practices.
Whether it’s a bug, disease, or weed, you need to identify it to know how to effectively manage it.
Accept a little damage — give nature time to work.
Natural predators often bring pests under control, but they need time to work. Don’t spray at the first sign of damage – nature may control it for you, or plants often just outgrow the damage.
