Super Self-Sufficient
Did some mulching this morning. I replaced some rotted wood with cinder blocks around the raised beds last fall. Weeds are growing through the holes - ugh. Talked to a friend a while ago and she said she puts cardboard in the bottom of the cinderblock hole, fills the hole up with soil and plants onions in the hole. Hmmm... I think I'll give it a try. I guess you wouldn't need to stop with onions... radishes, danver half-long carrots...a seed in each hole? Might not work well in the summer because I'll bet the blocks absorb heat. But, for fall/winter they should be ok. Love the idea. Not sure it'll work but you know I'll be trying it.
the possible issue there is the expansion and contraction of the soil in the holes which can eventually crack the cinder blocks. i know you don't have much issue with the freeze/thaw cycles down there but i'm not sure how much problem can come from the heat and cooling along short of freezing...
