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.
Broccoli prefers fertile, well-drained, moisture-retentive soil. When the young broccoli plants are 10-15cm (4-6in) high transplant indoor grown plants to their growing positions, leaving 45cm (18in) between them. Before lifting the plants, water them well and water well again after transplanting. Thin directly-sown broccoli to 30cm (1ft) apart. Water every 10-14 days in dry periods.
