Piccolo Sprouting Broccoli

Brassica oleracea var. italica

vegetable

Piccolo sprouting broccoli is a compact, tender variety that produces multiple small heads (8-10 cm) along the stem rather than one large central head. It matures quickly and offers a sweeter, more delicate flavor than traditional broccoli. This heirloom Italian variety is perfect for home gardens and small spaces.

Growth Stages

1

Seedling

2-3 weeks

Tiny cotyledons emerge, followed by first true leaves. Plant is delicate and low to ground.

Keep soil consistently moist. Maintain 65-75°F. Thin or transplant at 2-3 true leaves. Provide bright light to prevent leggy growth.

2

Vegetative Growth

3-4 weeks

Plant develops 4-6 true leaves and strengthens stem. Foliage is blue-green and robust.

Harden off transplants gradually before field planting. Maintain cool temperatures (55-70°F). Keep soil consistently moist and fertilize every 2 weeks with balanced fertilizer.

3

Stem Development

2-3 weeks

Plant grows taller and thicker. Leaf canopy expands significantly, shading developing heads beneath.

Ensure consistent watering and fertility. Mulch around base to retain moisture and keep soil cool. Monitor for pests weekly.

4

Head Formation & Sprouting

2-3 weeks

Multiple small heads develop along the main stem and side shoots. Heads are compact, tight, and deep green.

Maintain even moisture to prevent splitting or bitterness. Side-dress with compost or diluted fish emulsion. Continue harvesting lower heads to encourage upper growth.

5

Harvest & Production

4-6 weeks of active harvesting

Heads are ready to harvest when they reach 2-3 inches in diameter and before they flower.

Harvest main head first to stimulate side sprouting. Pick sprouts continuously to extend productivity. Plants can produce for 4-6 weeks with successive harvesting.

Harvest Tips

Begin harvesting the main central head when it reaches 2-3 inches in diameter and is still tight and green, before any flowers open. Cut with a sharp knife leaving 4-6 inches of stem on the plant. This stimulates profuse side shoot production. Harvest side sprouts continuously every 2-3 days at 1-2 inches diameter. Peak sweetness occurs when plants experience a light frost. Plants typically produce for 4-6 weeks; older plants may become bitter or woody.

Fun Facts

  • 🌱 Piccolo sprouting broccoli is descended from wild cabbage and was cultivated in Italy centuries ago; 'Piccolo' means 'small' in Italian, referring to its diminutive head size.
  • 🌱 Unlike standard broccoli which produces one large terminal head, Piccolo simultaneously develops 8-10 small heads along the stem, with side shoots continuing to produce after the main head is harvested.
  • 🌱 A light frost actually improves sweetness by converting starches to sugars; many gardeners time fall harvests for after the first frost for optimal flavor.
