How deep do you plant Acidanthra ‘Gladiolus Callianthus bulbs and how far apart? Do you then water them? And any other info I may need.
Plant your Acidanthera Gladiolus Callianthus corms 10-16cm (4-6in) deep and 3-4 inches apart. Water your corms moderately and avoid letting them get too dry. If in pots, stop watering at the end of Summer and bring them indoors for winter to protect against frost.
