Seed Depth: ½ inch

Seed Spacing: 10–12 inches

Row Spacing: 18–24 inches

Sunlight: Full sun to partial shade

Days to Sprout: 7–10 days

Days to Bloom: 50–60 days

Plant Height: 10–12 inches

Plant Type: Annual

Sunlight: Prefers full sun but will tolerate partial shade, especially in hot climates.

Soil Type: Thrives in well-drained, poor to average soil. Avoid high-nitrogen soils, which encourage foliage over flowers.

When to Plant: Direct sow outdoors after the danger of frost has passed. Does not transplant well due to delicate roots.

Direct Sowing: Soak seeds overnight to speed germination. Sow ½ inch deep and space 10–12 inches apart.

Indoor Sowing: Not recommended, as nasturtiums dislike root disturbance.

Succession Planting: Stagger plantings every 2–3 weeks in spring for extended blooms, especially in cooler zones.

Watering: Water moderately. Allow soil to dry slightly between waterings—nasturtiums prefer not to sit in wet soil.

Fertilizing: Avoid fertilizing. Rich soil can reduce flowering and encourage excessive leafy growth.

Mulching: Use light mulch to suppress weeds and retain moisture, especially in containers or raised beds.

Deadheading: Remove spent blooms to encourage more flowers and prevent unwanted reseeding.

Pest Management: Monitor for aphids, especially in dense plantings. Treat with neem oil or insecticidal soap if needed.

Deadheading: Regularly remove spent blooms to encourage continuous flowering through the season.

Harvesting Fresh Flowers: Pick flowers in the morning for the best flavor and texture. Both leaves and blooms are edible with a peppery bite, perfect for salads and garnishes.

When to Harvest Seeds: Allow seed pods to mature and dry on the plant. They will turn brown and fall off easily when ready.

How to Collect: Pick dried pods from the soil or plant. Gently open to reveal large, round seeds.

Drying and Cleaning: Spread seeds in a single layer in a dry, shaded area for several days. Ensure they are fully dry before storing.

Storage Tips: Store seeds in a labeled paper envelope or airtight container in a cool, dry place. Seeds remain viable for up to 5 years.
