My preparation is to remove all dead vegetation, and spread some compost. Rototill all areas and tend to lay a covering of wood chip mulch. My season is too short for a green cover crop. So basically come Spring, all I do if rake back the mulch and rototill if necessary and plant. Winter is starting this month, October, and it lasts until about the 15 of April, and active planting takes place around the 24 of May for most plants., During the winter on some nice days, I prune the various fruit trees as required. The only thing actively alive and growing somewhat is garlic and it will be planted this month about the 20 of October. The garlic bed is prepared and covered in wood chips.
My growing season is June, July, August and if lucky September. Frost, early and late, is always the inhibitor. But generally in my area, Zone 5, we have magnificent growth.
