I decided to experiment with my temperate CPs during dormancy this year. I dug a hole a little deeper than my 2 minibogs(they're around 1' tall, 1' wide 2' long) and placed them in. I figured that since the soil's temps are constant and usually warmer than freezing, and this might help stabilize temps and keep them slightly warmer in dormancy. Yesterday, it rained a little shy of 3 inches,and the hole was filled to the brim with water! They had a thin layer of clay from the soil on it, which I'm guessing is NOT good!!(There being those 'minerals in regular soil, ya know) I unpotted the plants, washed off all the soil, and I put them on hold in Ziploc bags.
NOW MY QUESTION IS: The minibogs have a drainage hole around 1 1/2" from the bottom. (t probably should be higher, but that's how these bogs were made) If I scraped out all the peat/sand with clay on it, and then flushed the bogs out with 5 gallons of water or so, would that leach out the extra minerals that the dirt/water put in? Or, should I redo the whole thing? I'd prefer the former method, but figgured I'd ask on here first.
I'd be extremely thankful for your help/insights!
