Sow seeds 5mm (¼”) deep, and aim for a spacing of 15-45cm (6-18″) between plants.
Calendula grows easily in any regular garden soil, and thrives in a pH range of 5.5-7.0. Pinch back young plants to encourage bushy growth. Occasional feeding is rewarded, but unnecessary. Keep plants watered, but try to avoid overhead watering as plants are susceptible to mildew. Deadhead regularly to prevent self-sowing.
Calendula repels a number of bad nematodes in the soil, but may attract slugs. Plant with tomatoes and asparagus.
