How to Plant Texas Super Sweet Onion from Seed

When to Plant Seeds

In southern regions (USDA zones 7-10), plant seeds in late fall (October-November) for spring harvest.
In cooler climates, sow seeds indoors 8-10 weeks before the last frost and transplant in spring.
Direct sow 2-4 weeks before the last frost in northern regions.

Preparing Seeds for Planting

  • Choose a location with full sun and well-draining soil.
  • Loosen the soil to 8-10 inches deep to accommodate bulb development.
  • Mix in compost or aged manure to boost nutrients.
  • Rake the soil surface smooth before planting.

Sowing Seeds Outdoors

  • Sow seeds 1/4 inch deep in rows 12-18 inches apart.
  • Space seeds 1/2 inch apart within the row.
  • Cover lightly with soil and water gently.
  • Thin seedlings to 4-6 inches apart once they reach 2-3 inches tall.
  • Mulch around the plants to retain moisture and reduce weeds.

Transplanting Seedlings

  • If starting indoors, harden off seedlings by gradually exposing them to outdoor conditions over 7-10 days.
  • Transplant when they reach 4-6 inches tall. Space transplants 4-6 inches apart in rows.
  • Water thoroughly after transplanting.

Pro Tip

For larger, sweeter bulbs, reduce watering during the final two weeks before harvest. This encourages the onions to concentrate their sugars, resulting in sweeter, more flavorful bulbs.

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

A 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.

Vacuum-Sealed for Freshness — Good for 10 Years

Every Shido seed packet is vacuum-sealed to lock in freshness and protect your seeds from moisture, air, and pests. This careful packaging not only preserves their quality but also extends their shelf life dramatically. Stored properly in a cool, dry place, our seeds remain viable for up to 10 years — so you can plant them now, next season, or even years down the road. Whether you’re planning a garden this spring or building a long-term seed stash, Shido seeds are ready when you are.
