Green peas are an early crop here in the north east part of the US. When you plant them, spring has started.
It’s important to get green peas planted early. They are a cool weather crop. A cool weather crop doesn’t like blazing sun or heat. If you plant the green peas too late, the plants will dry up, give up and lie down.
Green peas are ready to pick in early July. If the weather gets bad, the peas won’t like it. In normal weather, the peas are happy.
