Standard garden variety gladiolus corms can be planted November through March in your gardening region. If planted every two weeks, you'll have a succession of blooms. Glads normally bloom 65-100 days after planting. Glad corms should be planted about four times as deep as they are wide, and spaced 4"-6" apart. The soil should be amended with organic matter prior to planting, to provide nutrients and to help the soil retain just the right amount of moisture. A sunny site and weekly watering will produce healthy foliage and flowering stalks.
