Straw Bale Gardening

[T-oddity]

Would not use hay bales as they can contain grass seed so you could end up growing grass as well as a crop, I would stick to straw, you can prime the bales with natural fertiliser like comfrey juice or watered down urine if you do not wish to use a chemical fertiliser, make sure the bales are well soaked through before well in advance of planting your plants.
