|I'm wondering how long I should wait to compost lawn clippings after treating my lawn with a selective herbicide for broadleaf weeds.
I applied Scotts Weed Feed and Greenup to my lawn in late December, which is the height of summer here in Australia. Just over 3 months have passed and I guess I've mowed it around 6 times since then.
The active ingredients in the herbicide are Dicamba and MCPA.
I've just bought a compost tumbler and didn't really think about it until now.

|I hope someone can cite a good source.
I am not that cautious in general but in this case, I'd just let clippings lay on the lawn as I always do anyway.
However, if your lawn is sprouting broadleaf weeds now, one might say the herbicide must have broken down. There are probably a lot of variables but seeing broadleaf plants grow in that area seems to me the best test.
i'm pretty OK today, how are you? ;^)

I seldom use Weed and Feed, and my lawn shows it, it is just loaded with weeds. But, I do pick up lawn clippings from around the neighborhood and compost them. However, I only use the compost around my flowers.
Here is a very short paragraph( article) suggesting how long before using the clippings if you are using them around food crops as well as flowers.
