Q.

Need organic (or natural as possible) lawn moss killer, also a fertilizer and or weed killer

Hi, we live near Seattle so lots of moss everywhere. Lawn is now full of it and need moss killer. I have 2 dogs and we have tins of birds, bees and hummingbirds in the yard. Don’t want to poison them or add junk to the environment. I’m allergic to many things and sensitive to chemicals myself. Is there anything non toxic and preferably organic that actually works for these problems? I appreciate any advice you have! Thank you for you time! Laurie W

Cultural issues need to be addressed first, then you can move on to eradicate the moss with dish soap and water. Improving your lawn drainage will make the area less hospitable to moss. Also aerating the lawn will help. Have a soil test done, then add the nutrients needed. A thick lawn will discourage moss from growing. Only water when the lawn needs it, rather than on a schedule, to avoid standing water.

Then spot treat the lawn for moss with a mixture of 2 to 4 ounces of dish detergent with 1 gallon of water in a spray bottle. For larger areas use 4 ounces of dish soap to 2 gallons of water per 1,000 square feet. Use when rain is not predicted within 24 hours. When moss dies, rake it up. Continue treatment till all moss is gone.

There are organic fertilizers you can use on the lawn. Non chemical weed killers will kill the grass, too, but you can try spot treatments.
