I'm interested in straw bale gardening. Where can I find the bales

Try contacting your local govt for suggestions or find out from local farmers in your area.

At a home and garden store,or Tractor Supply store.

In our area, many nurseries sell straw bales. We also see farmers posting signs by the road selling straw.

depends on your area,research nurseries,every state is different

A local hay company, check with any stables around.

Your local feed store will have them. Make sure the bales you buy are Clean Wheat Straw.

The others will make weeds. : )

supermarkets and craft stores sell them now in anticipation of Halloween decorations. Good luck!
