Growing Broccoli and Cauliflower in Kansas

Cool-Season Brassicas for the Kansas Climate

Broccoli and cauliflower thrive in Kansas with proper timing and soil preparation.

Soil and Planting

• Cool, well-drained, loamy soil, pH 6.0-6.8.
• Amend with compost, aged manure, shredded leaves, and lime.
• Space 18 inches apart.
• Start seeds April to mid-July; transplant at 6-8 weeks, before 4-6 leaf stage.
• Succession plant every 2 weeks for continuous harvest.

Watering and Care

Water at base—large leaves block overhead irrigation. Use compost or manure tea at bud formation. These crops prefer spring and fall; summer heat causes bolting.
