Planting Instructions
When to plant:
- Broccoli can be planted in both the Spring and Fall. The seeds can germinate with temperatures as low as 40 degrees F.
How to plant:
- Broccoli needs full sun and moist soil.
- Slightly acidic soil is prefered - for soil testing, contact your local Agricultural Extension office.
- 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:
- 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.

Review
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.
