Cool, damp weather is forecast to continue this week. That means plants — flowers and vegetables — that need warm, sunny days to thrive are going to have to wait a little longer. So are gardeners. But be patient, says Cooperative Extension's Amy Ivy, they'll catch up.In the meantime, she says, pay attention to the lettuce, carrots and other seedlings that have come up. Use scissors to thin them out now. They'll thank you later!
