Evan,
My yard has a spring at the top of the hill that seeps into my garden. Many plants LOVE this but the semps not so much. I use raised beds that have a light soil mix that has compost and sand. I add chick grit around the plants, although less around the seedlings as they wouldn't enjoy the grit being higher than they are!
Anyway, that combo of beds raised 8" and the light soil mix is the trick. The semops now love my yard.
Kevin
