Radish seeds for the kitchen garden that intends to actually produce radish this year. Radish is the vegetable that grows while you are still deciding what else to plant.

Radish is the fastest vegetable in the garden -- ready in 20-30 days and the ideal crop for impatient beginners. Each packet is hermetically vacuum-sealed -- removing the oxygen that causes standard paper seed packets to lose germination viability within approximately one year. State law requires a 3-year viability label on sealed packaging. NASA research on hermetic seed storage indicates viability of up to 10 years under proper conditions. Every packet is non-GMO and germination-tested at independent third-party labs before it earns its Japanese woodblock print artwork.

How to Plant Radish from Seed

PlantCare

When to Plant Seeds

  • Spring Planting: Direct sow seeds 4-6 weeks before the last frost.
  • Fall Planting: Plant seeds 6-8 weeks before the first frost.
  • Radishes grow best when daytime temperatures are cool.

Preparing for Planting

  1. Choose a sunny location with loose, fertile soil.
  2. Remove rocks and debris to prevent misshapen roots.
  3. Work organic compost into the soil for better moisture retention.
PlantCare water

Sowing Seeds

  1. Plant seeds ½ inch deep and 1 inch apart in rows 12 inches apart.
  2. Water lightly after sowing to ensure good soil contact.
  3. Germination occurs within 3-7 days, depending on temperature.

Thinning Seedlings

  • Once seedlings reach 2 inches tall, thin them to 2-3 inches apart.
  • Thinned seedlings can be used as microgreens.

Pro Tip

Radishes grow fast, so plant them in succession every 1–2 weeks for a continuous harvest. Keep the soil loose and well-drained to prevent misshapen roots, and don’t let them sit too long—harvest when they’re young for the best crunch and flavour.

Bonus: The greens are edible too!

Getting to know your Raddish

Radishes come in a genuine variety of shapes, sizes, and colours, including red, white, pink, purple, and a striking black-skinned type, ranging from small, round varieties to elongated daikon types that grow considerably longer underground. They're widely considered one of the fastest crops a gardener can grow, rewarding impatience with a genuinely quick turnaround from seed to harvest. Radishes thrive in cool weather and loose, well-drained soil, developing their crisp texture and peppery bite fastest when growth stays steady rather than stressed by heat or drought. Consistent moisture matters more than people expect, since inconsistent watering is a common cause of radishes that turn woody or overly sharp in flavour rather than crisp and mild. Their quick life cycle makes them a natural choice for succession planting, tucking a new row in every couple of weeks to keep a steady supply coming rather than one large harvest all at once. Radishes also work well as a quick-turnaround crop planted between slower vegetables, making efficient use of garden space while something else takes its time. Few vegetables reward this little patience with results quite this fast. That speed alone makes radishes a satisfying first crop for anyone new to growing from seed.

Growth Requirements

Maintenance

Mulching:

Pruning & Harvesting:

  • Pull radishes gently from the soil to avoid damage.

Preventing Bolting:

  • Keep soil moist and provide shade during hot spells.

Refrigeration:

  • Store radishes unwashed in a plastic bag for up to two weeks.

Freezing:

  • Blanch radish slices before freezing to preserve texture.

Pickling:

  • Radishes can be pickled in vinegar and spices for long-term storage.
