Chard is an easy crop to grow and it produces leaves in abundance. We have grown it on the allotment, planting it as seeds in the spring. It is still growing well and has and abundance of leaves still waiting to be picked. It is similar to spinach but comes in a variety of colours - green, red and some with yellow stems.
For anyone starting out on growing their own food, I recommend chard.
We have been picking the leaves fresh and steaming or boiling them (they're lovely with a bit of melted butter though given my own environmental guidelines, we keep the butter to a minimum). When leaves are picked, new ones grow in their place.
We are experimenting to see how long the chard will continue to grow. We have already had one frost and it is still going strong. We may freeze some of it soon.
