Hi Pat, >> When you say six or eight inches "high", does that mean I should raise the soil level as well above the rest of the garden?<< No, that means that I wrote "high" when I meant "deep". <G> Make your trench 6-8 " deep and then line it with compost peat moss or a combination. I did mention using a bit of high phosphorous fertilizer. Don't go too heavy oryou take a chance on burning the plant. Avoid too much nitrogen because it will promotr foliage growth at ehe expense of roots, just what you don't want. I have to re- plant a couple that got unearthed in a real gully washer which we got yesterday. I'm gonna be all muddy but they have to go back in the ground before they dry out. Those are just some of the perils in maintaining a collection of heirloom tomatoes. Good gardening, Chuck Wyatt
