do you have any worms in that raised bed? I run my outdoor soil thru a steel mesh after every grow to remove all the roots and add a little bone meal, blood meal, a hand full of all purpose granular slow release fertilizer, chicken manure, worm castings, perlite, my own compost and use root farm soil to keep the soil from binding and allowing oxygen to enter, root farm is mostly wood chips and not a soil, grow medium I think. I takes me a full day in hot summer heat to do this, I have huge pots, do you think its necessary? cheers P.S. I always find allot of worms that make there way up thru the large holes I made at the bottom of my pots.
