They do well in a wide range of soil types - provided drainage is good.
Glads prefer full sunlight.
Plant Gladiolus corms when danger of frost has passed. Harvest before first hard freeze Planting at two-week intervals will ensure blooms over a longer period of time. Corms need to be placed three to five inches deep and four to five inches apart. If you wish, a little insecticide spread in the trench before covering will discourage underground insects. Before glads bloom, hilling soil five inches up around the stalk helps to prevent the Glads from tipping over during storms.
