How to Plant Radicchio from Seed

When to Plant Seeds

  • Spring Planting: Sow seeds 4-6 weeks before the last frost date.
  • Fall Planting: Sow seeds 8-10 weeks before the first frost.
  • In mild climates, radicchio can be grown year-round.

Preparing for Planting

  1. Select a sunny to partially shaded site.
  2. Loosen soil to a depth of 6-8 inches and mix in organic compost.
  3. Ensure good drainage, as radicchio does not tolerate waterlogged soil.

Sowing Seeds

  1. Plant seeds ¼ inch deep and 6 inches apart in rows 12 inches apart.
  2. Water lightly after sowing and keep soil evenly moist.
  3. Germination occurs in 7-14 days, depending on temperature.

Thinning Seedlings

  • Once seedlings reach 3-4 inches tall, thin them to 10-12 inches apart.
  • Use thinned seedlings as microgreens or early greens.

Pro Tip

Radicchio develops its best color and flavor in cool weather, so plant it in early spring or late summer. To encourage tight, crisp heads, trim outer leaves as it grows and give it plenty of water.

Bonus: A light frost enhances its sweetness and reduces bitterness!

Getting to know your Radicchio

Radicchio forms tight, compact heads similar to cabbage, though some varieties have more open growth habits. The leaves have a distinct bitterness, which mellows when cooked. Common varieties include Chioggia (round heads with deep red leaves) and Treviso (elongated heads with crisp texture).

What it's used for

  • Added to risottos, pasta dishes, or soups.

2. Nutritional Benefits:

Our Seed Safety Promise

We do not sell genetically modified seeds — ever. And we don’t use genetic engineering to breed new varieties. Instead, our skilled breeders use traditional, natural crossing methods to create hybrid seeds that are healthy, safe, and packed with potential.

Our Seed Quality Guarantee

At Shido, we believe great gardens start with great seeds — and that means quality comes first. Every seed lot we offer is ensure to generate top-notch germination because your garden deserves nothing less.

To keep our seeds at their peak, we run thorough pathology tests at trusted outside labs. When you open a Shido seed packet, you can trust it’s been nurtured, tested, and approved to give you strong, healthy plants from the very first sprout.

Types of Seeds We Offer

Hybrid Seeds (F1)

F1 hybrid seeds are the garden’s high achievers — created by crossing two specially chosen parent plants for superior vigor, uniformity, and performance. We use only traditional breeding methods to produce these powerhouse seeds.

Open-Pollinated & Heirloom Seeds

Our open-pollinated (OP) seeds naturally reproduce through wind, insects, water, or self-pollination. When grown in isolation, they produce true-to-type plants year after year.

Among our OP seeds are treasured heirloom varieties — old favorites that have been carefully passed down for generations. While OP plants can be less uniform than hybrids, we run our Open-Pollinated Project to select the most reliable, flavorful, and beautiful strains. Many are also available as certified organic seeds.

Non-GMO: What It Means and Why It Matters

GMO (Genetically Modified Organism) is created when scientists alter a plant’s DNA in a lab — often by inserting genes from completely unrelated species — to achieve certain traits, like pest resistance or herbicide tolerance. This is a far cry from natural plant breeding.

At Shido, we believe gardening should stay as close to nature as possible. All our seeds — whether hybrid, heirloom, organic, or open-pollinated — are Non-GMO. They’re bred using traditional methods that respect natural biodiversity, giving you safe, wholesome seeds that grow into plants just as nature intended.

When you plant Shido Non-GMO seeds, you’re choosing purity, sustainability, and peace of mind — along with a garden full of flavor, color, and beauty.
