I just stumbled on this thread and Dave, your last post is very interesting. I just happen to plant my basil next to my tomatoes. I had no idea it improves their flavor. In fact, when we were having issues earlier with something eating the tomatoes and I thought it was slugs since we had so much rain this year, my husband read that basil attracts slugs and I was ready to stop planting it near my tomatoes. (By the way, it turns out it was NOT slugs).
We planted borage one year but I had no idea what to do with it. So it is also a good tomato companion plant? I did remember somewhere reading to freeze the flowers in ice cubes.(who does that now days with automatic icemakers?
)
I think I'm going to have to hang around this forum. It looks like there's a LOT TO LEARN here!
