    How to Grow Calabrese Broccoli

    When to Plant Broccoli Seeds

    Broccoli can be planted in both the Spring and Fall. The seeds can germinate with temperatures as low as 40 degrees F.

    Where to Plant Broccoli Seeds

    Broccoli needs full sun and moist soil. Slightly acidic soil is preferred - for soil testing, contact your local Agricultural Extension office.

    How to Plant Broccoli Seeds

    Plant the seeds ½ inches deep in fertile soil. If planting in rows, plant 12-24 inches apart with rows 36 inches apart. Make sure to keep your broccoli plants watered, but take care to not get the developing broccoli heads wet while watering.For Spring planting: sow seeds indoors 2-3 weeks before the last frost. For Fall planting: sow seeds 85-100 days before the average Fall frost, during mid- to late-summer.

    When to Harvest Broccoli

    Harvest your broccoli when you see that the buds of the head are firm. Cut the stalk of the main head at a slant, and smaller side shoots will grow up from where you’ve cut.

    **If you live in a warmer climate, broccoli does best with a Fall planting. If you fear that your soil will be too hot, a layer of mulch will help ensure cooler soil temperatures. Make sure to harvest your broccoli before the yellow flower petals start to show - those parts have a mealy texture.

Seeds worked. I germinated seeds in wet paper towel in fridge

I germinated seeds in end of Aug in wet paper towel/ Baggie for a couple of days planted beginning of September. I got plants but I'm battling Cabbage looper caterpillars. Didn't know I had an issue till I found a butch of eaten seedlings. Just buy the seeds and give them a shot. I was surprised I got as many seedlings as I did.

Could have used more seeds in a pack compared to Spinach and Brussels Sprouts.

Part of the cold weather planting experiment.
