How to Grow Broccoli Sprouts in Water


Growing and eating sprouted seeds is an easy way to add fresh, home-grown vegetables to your diet. There is no need for an extensive gardening plot, and sprouts are ready to eat within just a few days. Broccoli sprouting seeds are readily available at health food stores and some groceries. The sprouts are suitable for use in sandwiches, salads and in other dishes. No special equipment is required to get started with sprouting broccoli seeds in water.

Step 1

Fill a clean glass jar with lukewarm water. Place 1 tablespoon of broccoli seeds in the jar. Broccoli seeds may float, so push any floating seeds into the water with the back of a spoon. Soak for 8-12 hours or overnight.

Step 2

Place a layer of cheesecloth over the top of the jar and secure with a rubber band or a metal canning ring. Pour out the soaking water from the jar. The cheesecloth keeps the broccoli seeds contained in the jar.

Step 3

Fill the jar with water again, pouring it through the cheesecloth. Pour this water out of the jar immediately.

Step 4

Place the jar in a cabinet or other warm, dark place. Rinse the seeds in fresh water twice a day, first filling the jar, then pouring the water out again.

Step 5

Move the jar to a well-lit area that is out of direct sunlight once the broccoli sprouts are approximately 1/2 to 1 inch long. This takes 5-7 days in most cases. Sprouts will turn green within 24 to 36 hours. Continue rinsing them twice a day during this time.

Step 6

Remove the cheesecloth from the jar and fill the jar with water. Stir the broccoli sprouts around in the water. This dislodges the tough seed hulls from the sprouts. Scoop the floating hulls out of the water.

Step 7

Drain the excess water from the sprouts and pat dry with paper towels. Use sprouts immediately or store them for 2-3 days in the vegetable drawer of the refrigerator.

Tips and Warnings

  • Use only untreated broccoli seeds meant for sprouting. Standard garden seeds are often treated with a toxic fungicide.
