Our hay is not the perfect mulch, as it does have some weed seeds, and sometimes mold. (Our garden gets the hay which is not good enough for the cows to eat.) If you have the choice, unsprayed straw is better than hay, as it won’t have many weeds. We don’t live in a grain-growing area, so there is no local straw for sale.
We bale hay into big round bales, and move them around with the tractor and forks or a rear bale spike (spear). We plan our beds to be 5′ apart on centers and our rows to be 5-5½’ apart (tomatoes, for example) . We prepare our beds and get the mulch dropped off at the uphill end (even a small slope is helpful!).

Transplanting into hay or straw mulch, organic myth-busting, keep soil in Organic
The Organic Trade Association has published a set of 33 little posters putting solid information out there, and busting some myths about organic agriculture . Here’s one with a photo on our cabbage theme.
We grow our own hay, so we know it is unsprayed – there is a danger from pyridine carboxylic acids, a class of broadleaf herbicides which persist through composting and even through the digestive systems of livestock, and can kill or seriously damage food crops and flowers. Grazon is one brand; picloram is the plant growth regulator it contains.
There is a “Keep the Soil in Organic” movement, which advocates for Organic certification requiring plants to be grown in soil, not water-plus-some-nutrients. Dave Chapman sent me this message asking for support for the National Organic Standards Board on 3/27/17:
We remove the twine (if it hasn’t already rotted and fallen off) and study the end of the bale to figure out which way it will unroll. This can be surprisingly unclear. If we have to turn the bale, or maneuver it to line up, we might have three people do that. Once it’s rolling, two people can manage to unroll a round bale of hay. We spend some time at the end using wheelbarrows to move hay from the thick places to the thinner spots.
