This would be great for keeping track of which soil blend is in which raised bed!
Each growing season, I end up topping off the beds or refreshing the planters with something-or-other, and have often wanted a way to keep track of which "recipe" went where, to compare the growth of varieties growing in multiple locations. I'd like to know if adding those "5 hands" of worm castings made a difference, LOL!
The white board, sharpie and eraser should do the trick. Just snap a pic ( I never go into my garden w/o my camera phone, either), and now I'll have a record of the "recipes!" Additionally, snapping a pic of the different growing locations will tell the tales regarding light exposures, too!
Thanks!
