'Naughty Marietta' (Tagetes patula) - a flirtatious French heirloom with radiant golden petals dramatically blotched in velvety burgundy — each bloom a mischievous wink. Grows only 25–30 cm tall and wide, ideal for railing planters, pots, window boxes, or tight HDB corners. Blooms in 45-50 days, providing non-stop blooming for 5-7 months in our humidity; Flowers are fully edible with a gentle citrus-spice note — perfect floated in cocktails or scattered over salads. Super easy to grow, 100 % beginner-proof — germinates in 4–6 days even if you forget to water once.
Natural mosquito deterrent and strongly repels root-knot nematodes in soil — plant around tomatoes for natural protection.
Growing:
Sow directly in garden or pots year-round; best during cooler parts of rainy season for easier establishment. Surface-sow (barely cover) in seed-starting mix; seeds need light to germinate.
Germination: 5–7 days at 22–28 °C soil temperature. Spacing: 15–25 cm apart (dwarf varieties).
Light: Full sun (6–8+ hours daily); tolerates light afternoon shade in 35 °C+ heat.
Soil: Well-draining, moderately fertile loam; pH 6.0–7.0. Avoid rich, wet soils — promotes foliage over flowers. Containers: Use 15–20 cm pots with drainage holes; excellent for patios.
Watering: Keep soil evenly moist during establishment (first 2–3 weeks). Once rooted, water 2–3 cm per week in dry spells; reduce in monsoons. Never let soil stay waterlogged — root rot is common in humid tropics.
Fertilizing: Light feeder: Apply balanced liquid fertilizer (10-10-10) at half-strength every 4–6 weeks. Avoid excess nitrogen — causes leggy growth and fewer blooms. In poor soils, mix in compost at planting.
Common issues in tropics: Spider mites & thrips in dry heat — hose off or use neem oil. Fungal leaf spot or powdery mildew in high humidity — improve airflow, avoid overhead watering.
Companion planting: Excellent near tomatoes, eggplants, and peppers.
