Growing Broccoli: From Transplant to Harvest

Care Upon Arrival

Your broccoli starts may show yellowing or wilting after up to three days in transit. Over 98% recover with proper care. Unpack immediately, handling gently. If soil is dry, water thoroughly or soak the pot in a saucer of water for an hour until moist but not soggy.

Place in bright, indirect light indoors or in a sheltered, shady spot outdoors. Avoid direct sun initially—tender leaves scorch easily. Gradually increase sun exposure over several days.

If frost threatens, pot up into larger containers and harden off by placing outside on mild days, bringing in at night. Wait until nighttime temperatures consistently stay above 50°F before planting in the garden.

Planting in the Garden

Choose a full-sun site with rich, fertile, well-drained soil. Practice crop rotation: avoid planting broccoli where cabbage-family crops (cabbage, cauliflower, kale, etc.) have grown in the past three years to reduce soil-borne diseases.

Dig a generous hole, mix in compost or aged manure plus a handful of low-nitrogen organic fertilizer. Plant in the cool of morning or late afternoon if hot. Space according to label recommendations.

Remove from pot by tapping the bottom—don't pull by the stem. Loosen matted roots. Set the plant so the top of the root ball is level with or slightly below the soil surface. Backfill, firm gently, and water thoroughly. Provide temporary shade (row cover, cardboard) for a few days until plants perk up.

Ongoing Care

Water deeply and regularly if rain is scarce—weekly or more in hot weather. Mulch to retain moisture and keep soil cool. Side-dress with compost or balanced fertilizer about three weeks after transplanting.

Harvesting

Cut the main head while firm and tight, before yellow flower buds open. Harvest secondary side shoots regularly to extend production.
