I now have 5 bales for planting, one older bale that was pulled from compost pile protection duty (now planted with trailing squashes) , 2 older bales that were starting compost pile duty (and I struggled to tip over end to end to their new site), and 2 fresh bales that hopefully have aged enough to support plants. The latter are yet to be planted.
I justified this by buying 4 new straw bales to take on compost protection duty (from our gardening assistant, aka Mocha our Golden Retriever, who loves compost scavenging, which gives him indigestion.)The premise behind straw bales is excellent -- start the straw decomposing, whether with ammonium nitrate or compost tea or rain water. Dig out a spot to put in potting soil or compost, plant, and proceed to keep the bale moist and nutrient-rich, with added nutrients, compost tea, slow-release fertilizers, or even inoculations of mycorrhizal fungi.
And, then plant, either in an excavated hole filled with compost or potting mix, or simply poking a transplant between the straw. I'm opting for the former, even though straw bales are really just a form of hydroponic gardening.
