When to plant broccoli raab. Broccoli raab is more of a cool-weather vegetable, so grow it for a spring/early-summer harvest as well as in fall. Plant young plants into the garden when the soil temperature is above 55-60F. Broccoli raab is a âgreensâ item, like chard and kale, and as such enjoys plenty of nitrogen. When planting, add a good helping of compost to give it a great, nutrient-filled send-off into the season. Plants should be about 4-6 inches apart from one another. Another key to growing broccoli raab is water, water, water.
