There are greens you can grow in every season- even winter.
Some garden greens, like spinach, grow quickly and last just a short time. Others, such as chard, remain ready for picking all season long.
Most greens thrive in cool weather. Some, in fact, such as kale and Chinese cabbage, are at their best after frost.
With some planning, you can pick your own fresh greens from spring through winter. The secret of a continuous harvest is succession planting.
