How to tell it is ready

Leaves can be picked once they are large enough to use, usually when outer leaves reach about 8 to 12 inches long. Look for full-sized, deep green leaves that still feel flexible, not yellowing or tough.

How to harvest

Harvest the lowest, outer leaves first by snapping them downward cleanly or cutting them close to the stalk with a knife. Leave the center growing point and smaller inner leaves in place so the plant keeps producing.

Timing

Collards are often ready for first harvest about 50 to 75 days from sowing, though baby leaves can be cut sooner. Harvest in the morning for best crispness, and make repeated pickings from the outside in. Flavor is often best in cool weather.

After the harvest

Cool leaves promptly and keep them shaded while picking. Rinse off grit, dry well, and refrigerate in a bag or container with some airflow. If needed, trim thick stems before storing.

Tips

Use cut-and-come-again harvesting by taking outer leaves and leaving the center. Do not strip too many leaves at once from a small plant.
