How to grow Costa Silver Snapdragon seeds
Step 1: Start Indoors (Recommended)
When: 8–10 weeks before the last expected frost.
Containers: Use seed trays or small pots with good drainage.
Soil: Use light, well-draining seed-starting mix.
Sowing Depth: Lightly press seeds into the surface – do not cover, as they need light to germinate.
Moisture: Mist or gently water to keep soil evenly moist.
Light: Place under grow lights or in a bright window (14–16 hrs/day).
Temperature: Keep at 60–70°F (15–21°C).
? Germination Time: 10–21 days
Step 2: Transplanting
When: After the danger of frost has passed and seedlings have 4–6 leaves.
Hardening Off: Gradually expose plants to outdoor conditions over 5–7 days.
Step 3: Outdoor Planting
Spacing: 6–12 inches apart depending on the variety.
Location: Full sun to partial shade.
Soil: Well-drained, slightly acidic to neutral soil (pH 6.0–7.0).
Mulch: Add a layer to keep soil moist and suppress weeds.
Step 4: Care
Watering: Medium – keep soil consistently moist, but not soggy.
Fertilizer: Use a balanced, water-soluble fertilizer every 3–4 weeks.
Deadheading: Remove spent blooms to encourage continuous flowering.
Staking: May be needed for taller varieties to prevent bending.
?? Bloom Time: Late spring through summer (can extend into fall in cooler climates)
