Gardeners' Quotes
"You can tell which diseases tomatoes are resistant to by looking for letters such as V, F, N and T after the name of the tomato. Each letter represents a problem the plant is bred to resist, and the more letters the better!" ---from Orene Horton's book, "Clippings from Orene's Garden"--- |
