They work!
I just put these in my new raised beds 2 weeks ago. And then I realized I had major problems with my soil and had to dig everything up. What I discovered when I removed the soil was that all of the minor roots had already found the ollas - in 2 weeks all the plants knew they were there!<br />I am convinced and will buy more until  they are in every bed in my garden:)
