Last year I planted tomatoes in bad soil and they did great. This year we've made our first raised beds with great soil and the tomatoes look terrible. They were attacked by hornworms during our absence and though I think I've gotten them all off, the damage was serious. What to do now? The plants are about 6' tall, and the tops were seriously eaten; many of the flowers are brown. One plant has almost no fruit. Should I pull it up, or is there a chance they will recover?
