Gladiolus
Gladiolus
Showy summer bloomer excels as a cutflower. Each stalk is covered with 10 or more open funnel-shaped flowers that bloom from bottom to top. Named for their sword-like leaves; a gladiolus is a small Roman sword. Each stalk blooms for about a week, roughly 8 weeks after planting.
Growing Gladiolus
Soil: Prefers moist well-drained soil. Mulch to retain moisture and suppress weeds.
Sun: Full
Spacing: 5" deep, 8" apart, after danger of frost.
Planting schedule: Stagger plantings for a long season of blooms: First planting in early to mid-May, then again every two weeks through mid June. This will keep the flowers coming July through August.
Harvest: Hill or stake to keep plants from keeling over when flower spikes get top heavy. Cut when 2–3 blossoms have opened, taking care to spare the leaves, which feed the developing corm.
Overwintering: Dig corms after the tops have died, discard the old one, clean the new one, allow it to dry off, and store in paper bags in a well-ventilated cool (35–45°) dark dry place.
