Setup, Compatibility & Care
Sowing Seeds: Sow seeds indoors from January to April or directly outdoors from April to May. Sow thinly in pots or trays of compost, or rake into prepared soil. Cover lightly with compost or soil. Germination typically takes 14-28 days. Thin outdoor sown seedlings to 45cm (18 inches) apart. Harden off indoor-sown plants before planting out after the risk of frost has passed.
Planting Location: Choose a sunny or partially shaded spot with well-drained soil. Avoid heavy, waterlogged clay.
Watering: Water regularly, especially during dry spells, until plants are well established. Reduce watering once established, but water during prolonged droughts.
Feeding: A light feed in spring with a balanced fertilizer can be beneficial.
Aftercare: Deadhead spent flower spikes to prevent seed formation and potentially encourage a second, smaller bloom. Cut back foliage in autumn.
Pest & Disease: Be vigilant for slugs and snails, especially on young plants. Ensure good air circulation to minimize fungal diseases.
