Plan a fresh, cool-season harvest with broccoli seeds from David's Garden Seeds®. Broccoli brings crisp texture and garden-fresh flavor to your kitchen, whether you enjoy it steamed, roasted or added to stir-fries. Compare the varieties below for maturity and harvest characteristics that suit your garden.

Give Broccoli a Cool-Weather Start

Broccoli grows best in cool conditions. Plan spring or fall planting dates around your local climate so plants have time to develop before prolonged heat. Cold tolerance and the tendency to flower early vary with the variety, plant maturity and growing conditions, so follow the guidance on each seed packet.

Start seedlings ahead: Sow indoors about four to six weeks before your planned transplanting date, following the packet's directions for sowing depth and germination conditions.
Harden off gradually: Introduce indoor-grown seedlings to outdoor light, wind and temperatures over about a week before transplanting.
Prepare a productive bed: Choose a sunny site with fertile, well-drained soil and give plants the spacing recommended for the variety.
Keep growth steady: Water consistently and use mulch to help conserve moisture. Watch young plants for caterpillars and other common brassica pests.

Harvest While Buds Are Tight

Cut broccoli heads while the flower buds are still tightly closed, before they open into yellow flowers. Some varieties produce additional side shoots after the main head is harvested; check the individual listing for the variety's growth habit. Refrigerate harvested broccoli promptly to help preserve freshness.
