For those of us in warmer climates, this is actually the most intensive time of year. There's a lot to harvest from long season hot weather crops (winter squash, cowpeas, okra, and sweet potatoes for me), but there's also an urgent need to get the fall vegetables (mustards, beets, carrots, brassicas, peas, Irish potatoes) in the ground. I am often conflicted about whether I should leave the summer plants in to continue producing at the risk of being too late getting the fall plants in. This year I compromised by harvesting half of my sweet potatoes to make some space. Anyway, my point is that there is no rest season for the garden here, so adding compost, mulch, etc happens at various times throughout the year. I add mulch in the form of poultry bedding or lawn clippings under growing plants or a few weeks before planting heavy feeders. I also chop and drop crop residue at harvest time and this can be a lot of biomass for things like sweet potatoes. It's a constant churn.
