How to grow Pandemonium Sweet Pea seeds

Choose Your Planting Method

• Indoors: Sow indoors 4-6 weeks before the last frost in deep pots or root trainers — sweet peas make long taproots.
• Outdoors: Sow directly outdoors in early spring as soon as the soil can be worked, or in autumn in mild climates for earlier flowers.

Prepare Your Materials

• Seed-starting trays or pots (if indoors)
• Well-draining potting mix
• Deep pots or root trainers for the long taproots
• Spray bottle for misting

Sowing the Seeds

• Soak seeds in room-temperature water for 12-24 hours; nick any seeds that do not swell with a small file and return them to the water
• Sow about 1 inch deep in moist seed-starting mix

Provide the Right Conditions

• Light: Bright light after germination; grow seedlings on cool and bright so they stay stocky
• Temperature: 55-65°F (13-18°C) for germination

Germination

• Germination takes 7-21 days in cool conditions
• Move seedlings to a cool, bright spot (around 50°F / 10°C is ideal) so they develop strong roots rather than leggy stems

Transplanting

• Transplant after frost danger has passed, disturbing the roots as little as possible
• Harden off over 7-10 days
• Space plants 6-12 inches apart at the base of a trellis, netting, or canes

Care Tips

• Sun: Full sun
• Water: Keep soil evenly moist; do not let plants dry out in warm weather
• Fertilizer: Feed lightly once established; rich soil is not needed
• Provide support early — put trellis or netting in place before the vines start climbing
• Pinch out the growing tip once seedlings have 2-3 sets of true leaves to encourage branching, and pick flowers regularly to extend the display

Bloom Time:

Late spring into summer; plants fade as hot weather arrives.
