Yard care and water savings tips
Part Two of Think twice before using pesticides.
If a pest or weed problem develops, use the least toxic solution.
Physical controls like traps, barriers, fabric row covers, or repellants may work for pests.
Long handled weed pullers pop dandelions out easily.
Mulching once a year reduces weeds in beds.
Less toxic products like soaps, horticultural oils, and plant-based insecticides that work for many problems are now available.
Beneficial insects that prey on problem bugs are available for sale, or you can attract these “good bugs” by planting a variety of plants that provide pollen and nectar all year.
Use chemical pesticides as the last resort. If you must use a chemical pesticide, use the least toxic product, and spot apply it — don’t spread it all over the yard to kill a few weeds or bugs. You want to apply pesticides only when and where you really have a problem. Follow label instructions exactly — more is not better and be sure to keep children and pets out of application areas.
Replace problem plants with pest resistant ones for a healthier, easier to care for yard. If a plant, even a tree, has insect pest or disease problems every year, it’s time to replace it with a more tolerant variety or another type of plant that doesn’t have these problems.
