@MaryE -- thanks for the explanation, I apparently forgot about your other post! I always plant my tomatoes pretty deep so they can get a good root development; I think I've read that using a trench and planting the lower part of the plant horizontally (which I think is what you're describing) provides more soil warmth and better growth for the plants in colder areas - such as where I am - but I've tried that method as well as just putting them into a normal hole and haven't really seen much difference.
@dave -- would the suckers coming from the plant that's been grafted onto the rootstock have the rootstock characteristics? or just any that happened to come up from the lower part of the plant? At any rate, if all the suckers have to be kept cut off for whatever reason, that would definitely be a deal breaker for me, too! It sounds like it might be fun to experiment with the grafted plants but can't see them being very desirable for the purposes of most "gardeners." (or is that what people were saying when hybrids first became available...
)
