I know that Imbolc is a good time to cut back my roses, but that's about all the info I've learned over the years about how gardening should be based on the Earth's cycles. I'm not talking about general "this is what you should do in the Summer"; what I'm getting at is faith-based planting, harvesting, etc. based on the Pagan calendar/beliefs/Sabbats/Esbats, etc. If I'm supposed to trim my roses back at Imbolc, what should I be doing at Beltaine? Yule? Litha? Anyone know where I might find this info?
