SEED TREATMENT
- Scarify: Nick or gently sand the seed coat to help water penetrate.
- Soak: Soak scarified seeds in warm water for 12–24 hours before planting.
WHEN & WHERE TO SOW
- Indoors: Start 4–6 weeks before the last frost in biodegradable pots for easy transplanting.
- Outdoors: Sow directly after last frost once soil is warm.
- Location: Choose a sunny spot (at least 6 hours/day). Ideal for trellises, fences, or railings.
OPTIMUM GERMINATION CONDITIONS
- Temperature: 21–27°C (70–80°F)
- Germination Time: 10–30 days
- Keep the soil consistently moist (not soggy) during germination.
SOWING INSTRUCTIONS
- Depth: 1–1.5 cm (½ inch)
- Spacing: 30–45 cm (12–18 inches) apart
- Soil: Well-drained, fertile soil. Add compost for best results.
POST-GERMINATION CARE
- Light: Full sun is essential for vigorous vines and blooms.
- Watering: Water regularly, especially during dry spells, but allow soil to dry slightly between waterings.
- Support: Provide a trellis or fence for climbing.
- Feeding: Use a balanced liquid fertilizer every 3–4 weeks during growing season.
- Pinching: Pinch tips of young vines to encourage bushier growth.
BLOOM TIME
- Flowers begin in mid to late summer and continue through fall. Blooms open in the evening and close by morning.
TIPS
- Moonflower is a tender perennial (USDA Zones 10–11), grown as an annual in cooler climates.
- Not frost-tolerant—plant only after all danger of frost has passed.
- Can be grown in large containers with support.
