We'll be having home grown potatoes, sweet potatoes, onions, and garlic in the Thanksgiving Day feast next week. I wish I could grow celery, but so far nada out of two attempts. And yeah, I have to buy eggs right now. Maybe the Christmas feast will be different in that regard.
None of those items is expensive to buy, really. Until you compare apples to apples and say, ok, I want organic versions of those. So my cost for these is the onion sets and sweet potato slips I bought. I had the cloves to plant for the garlic, and the seed potatoes.
