Just wondering if any one has tried this. I have very poor soil so growing in raised beds and need to bring in my own soil. I am considering diving holes big enough. To burry 5 gal pails and planting my squash, and climbing plants in the pail, my thought is this will keep the high quality soil in the pail and close to the plant and keep weeds out. Any input would be great. Fairly new to this and first couple years were very disappointing but I refuse to give up.
