I would much rather muck out a stall or clean out the chicken coop than weed. And my flower beds back me up.
There are some that are fail-safe.
They are past their zenith, now, but, boy they were lovely a couple of weeks ago.
I had everything I needed except the Idaho Tansy and had to substitute Lemon Myrtle for the Lemongrass. But then I got thinking (uh oh). Would the oils mix with plain ole' water? I again looked online, found suggestions for emulsifiers and then asked husband Rick, the biologist/chemist in the family. His suggestion of vigorous shaking just before applying said concoction served my purpose.
I've only been experimenting for a couple of days but thus far, I'm pleased. I'll have Luigi report back after a longer test period.
