A frugal hint that might not apply to all climates, but works nicely in our climate where we only get mild freezes is to plant a winter crop of lettuce. We have a neighbor who planted several kinds of lettuce and arugula and he shares with several of us in the neighborhood. I go over 2-3 times a week and pick enough for salads for my husband and me. I usually get plenty for two meals each time and it is delicious--so much better than what we get in the store. This fall I planted some chard, kale, cilantro and a bit of purple lettuce. It has grown well despite our drought and a couple of freezes. It is nice to have these fresh items in our salads and know that they have not been treated with pesticides or chemical fertilizers. Best of all is that they are not costing us an arm and a leg in the store.
