For a striking flower show and stunning cut flowers, grow gladiolus. This spring planted corm (bulb), quickly produces flower spikes in a variety of colors that pop. This makes them a first choice for ‘tucking into’ young flower beds that could use some bulking up until they reach maturity. Glads also make excellent cut flowers grouped together in a vase or mixed with other flowers in arrangements. When & Where to Plant Gladiolus Light: Gladiolus grow and flower best in full sun. Gladiolus corms will flower in part shade, but the colors will not be as vivid as when planted in full sun, and the plant won’t grow quite as well. Soil: Gladiolus like well-drained, sandy loam soil. The corms will rot if the soil is too heavy and wet. If you have clay soil, grow in raised beds and loosen the soil to 12 inches deep before planting. Spacing: Space gladiolus corms 6 to 10 inches apart in the garden and plant corms 2 to 6 inches deep depending upon the size of the corm (plant bigger corms deeper). Planting: Plant gladiolus corms in spring 2 weeks before your last expected frost date. To enjoy flowers all summer, plant your Glads every 2 weeks until early July. This will stagger the plantings and flowering times. You can also extend the flower season by growing early, mid and late-season Gladiolus varieties.
