Preparing the Planting Site

  2. Loosen the soil and mix in organic compost for added nutrients.

Sowing Seeds Indoors

  1. Fill seed trays with light, well-draining potting mix.
  2. Sprinkle seeds on the surface and do not cover with soil, as petunia seeds need light to germinate.
  3. Mist lightly with water to keep the soil moist.
  4. Cover trays with plastic wrap to maintain humidity.
  5. Keep at a temperature of 70-75°F (21-24°C).
  6. Germination takes 10-21 days.

Transplanting Seedlings

  1. Once seedlings develop two sets of true leaves, transplant them into individual pots.
  2. Harden off seedlings by gradually exposing them to outdoor conditions over 7-10 days.
  3. Plant outdoors after the last frost, spacing them 10-12 inches apart.

Pro Tip

For a continuous bloom, deadhead regularly and feed with a balanced fertilizer.

Getting to know your Trailing Petunias

Trailing petunias are cascading flowering plants known for their abundant, trumpet-shaped blooms in colors ranging from pink, purple, white, red, and yellow. They are widely used in hanging baskets, window boxes, and garden borders, where their long, trailing stems spill over edges gracefully. These sun-loving annuals thrive in well-drained soil and require regular watering and fertilization to produce continuous blooms throughout the growing season. Petunias are highly resistant to heat, but deadheading spent flowers promotes better blooming. Some popular trailing varieties include the Wave and Surfinia series, which are known for their vigorous growth and exceptional flower production. Petunias attract hummingbirds and butterflies, making them excellent additions to pollinator-friendly gardens.

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.
