Answer: Gladiolus are effective in the garden for a week or so, and most gardeners plant them at about two week intervals to have a continuous supply of blooms. They make an attractive accent in the garden and are also great cut flowers. Plant them about 6 inches apart -- they take very little room, but also plan on staking the taller ones. Start planting in mid spring and expect them to take from 70 to 100 days to bloom; stop planting by late June or early July.
