General Sowing Time: Sow Sweetpea Mammoth Mix seeds indoors 6–8 weeks before the last frost, or directly outdoors when soil temperatures reach 12°C–15°C.

Suitable Space: Ideal for garden beds, fences, pergolas, archways, and trellises, adding height and color to any landscape.

Sow Depth: Plant seeds 1-2 cm deep, covering lightly with soil. Soak seeds for 12–24 hours before sowing to enhance germination.

Spacing: Space plants 20–30 cm apart to ensure proper airflow and room for climbing.

Height: This vigorous variety can grow 150–200 cm tall, making it perfect for vertical garden spaces.

Germination: Seeds typically germinate within 10–14 days at temperatures between 18°C–20°C. Keep soil moist but not waterlogged.

Days to Bloom / Harvest: Expect flowers 70–90 days after sowing, with continuous blooms throughout summer when properly maintained.

Temperature: Prefers moderate temperatures between 15°C–22°C. Sweetpeas perform best in cool weather and may struggle in extreme heat.

Watering: Keep the soil consistently moist, especially in dry periods. Water at the base to avoid wetting foliage, which can lead to fungal diseases.

Fertilizing: Apply a balanced liquid fertilizer every 4–6 weeks to encourage vigorous growth and abundant flowers. Avoid excessive nitrogen to prevent too much foliage at the expense of blooms.

Pests/Diseases: Watch for aphids, spider mites, and powdery mildew. Use natural pest control methods like neem oil or insecticidal soap. Ensure good air circulation to prevent fungal infections.
