Bok choy, also known as Pak choy or Chinese white cabbage, is part of the cruciferous family of vegetables, which also includes broccoli, cauliflower and kale.

There are many different types of bok choy including large bok choy, Shanghai baby bok choy and dwarf bok choy, and the process of collecting and saving the seeds is the same for all varieties.

Collecting bok choy seeds is a great way to save money, and you can grow your favorite varieties every year without ever needing to buy more seeds.

You can also share some of the seeds with your gardening friends or contribute to a seed bank in your local area.

How does bok choy produce seeds

Bok choy plants begin to bolt (go to seed) when the weather gets hot.

They produce tall flower stems that can grow up to 2 feet (60 cm) tall, with an abundance of small yellow flowers.

The flowers attract plenty of bees and other pollinating insects and they look quite pretty in the garden.

The flowers only stay on the plant for a short time and then they fall off.

After the flowers fall off you’ll notice long green seed pods beginning to form.

If you’ve had lots of pollinators visiting your garden you’ll have an abundance of seed pods.

Each bok choy plant will produce hundreds of seeds so you only need to allow one or two plants to go to seed.

You can leave the plants in the garden to dry out completely or cut them off at the base and hang them up in your garage to allow them to dry out.

Open one of the pods and if the seeds are black, then they’re ready to harvest.
