This week: last chance to plant beets, carrots, and rutabagas for late fall/winter harvest. If it's hot, a cover of burlap or newspaper will help keep the seedbed moist until the seeds sprout (Remove this as soon as they have sprouted).
This is also the time to plant seeds for overwintered cauliflower, to be harvested next spring. If you didn't get seeds for this crop this year, make a mental note to get them when you order seeds next winter. It's the sweetest cauliflower you will ever taste, and great to have at that time of year.
Look for and prepare a place where you will be able to sow hardy greens in a couple of weeks-- chard, kale, arugula, spinach, Chinese cabbage and other Asian greens.
