The dry weather has taken a toll on our lawns and plants this summer, but proper watering is important to keep them maintained.
Richard Halopka, with UW-Extension in Clark County has some tips.
1. Best time to water- early in the day, allows plants material to dry during the day reducing the chance for disease development.
2. How often should I water plants/lawns? Many will water every day, that would be the worst method. This watering method could promote root disease. Best to have a dry period between watering to prevent conditions that may promote root disease. Best method is to water 2 or 3 times a week with adequate water each time.
3. What is adequate watering of a lawn or plants? A rule of thumb is 1 inch water per week, either as rainfall or irrigation. Remember soil is a bank for nutrients and water. Soil may contain up to 10 or more inches of soil water, depending on soil type.
4. How much water is required on a lawn or plants? If you have a 1 acre lawn 43 560 sq. ft., 1 inch of water is 27,000 gallons of water. A 2500 sq. ft. lawn (50x50) would require 1600 gallons of water per week. A 10,000 sq. ft. would require 6200 gallons of water. Plants, pots etc. will require about 5 gallons per week, larger plants or pots may require more.
5. When should I start watering my lawn? Before it goes into doormat mode. If your lawn is turning brown and is doormat it may cause more stress unless you provide continuous watering at adequate levels which may exceed the 1 inch per week until some soil water is replenished.
