Were these from the Hoop House? Oh, we screened my keyhole garden day before yesterday and the soil temp was 93 degrees, my friend keyhole was 113 (this garden wasn’t screened) and her other keyhole garden in her back yard semi under a tree was 88 degrees. These gardens are very interesting. I’m going to tear down my 16’x4’x2’ high and put in 3 keyhole gardens, they are so easy to maintain. I’m going to put some red wigglers in one.
I haven't checked soil temperatures. I have a pot filled with catnip that I use as a gauge. When the catnip starts to shrivel, I turn on the watering system for a couple hours until it begins to recover.
We're planning a keyhole garden also, but I want to cover mine with a dome-type structure (to keep the deer away). It may be awhile though. Other projects take precedence.
