Gladiolus grows best in sandy, well-drained soil rich in organic matter in full sun. After last frost, dig a trench 8" deep. For a flower border, dig a roundish or oval hole to give a more natural look than the soldier-like rows of a cutting garden. Add compost and bulb food to the trench, using one cup per 10' of row. Cover with 2" of soil. Firmly place bulbs on soil, pointed ends up, 6" apart. In a flower border, plant a group of at least 10 bulbs for best effect. Cover with remaining soil. Water well and add 2" of mulch to conserve moisture and keep the roots cool. Begin planting in mid spring and continue to plant every two weeks until mid July for flowers throughout the summer. Bulbs will bloom from 70- 100 days from planting, depending on the lateness in the season. Tall-growing varieties may need staking. Water well throughout the growing season. Fertilize when the flower spikes first appear and after the flowers are picked. Grows 3-5' tall. Gladiolus are susceptible to thrip infestation. To avoid problems, soak the bulbs for 2-3 hours just before planting in a solution of 4 teaspoons of Lysol in 1 gallon of water. Dig up the corms 4-6 weeks after the flowers fade. Remove as much soil as possible and cut off flower stalk 1" above corm. Dry and store the bulbs indoors for the winter. Hardy in zones 8-11.
