Hello.
I have been busy experimenting with certain aspects of the method. There are a few things I think might help you.
1. You MUST soak the bale completely when you first start to mature the strawbale.
2. When growing potatoes cut the top twine.
3. Use the best quality compost to sow in you can afford.
4. Use the whole of the bale, think space.
I am experimenting with Strawbale Gardening under cover, and will keep you informed.
Like all forms of growing, strawbale gardening is a slave to mother nature and nothing in gardening is set in stone.
GOOD GROWING
Simon.
