did you know?

The name gladiolus, bestowed by Pliny the Elder, is derived from the Latin word for sword, which refers to the plant’s distinctive foliage. Most modern hybrids descended from South African species, and because of their complicated heritage, traditional species classification is impossible. Gladioli are thus classified by their flower size, color, and shape.

general maintenance:

In Zones 7 and colder, dig corms 6 weeks after flowering or after first frost; cut off foliage, and allow corms to dry. Once dry, remove the old corms from the new, and compost the old. Store corms in a cool spot (40°F), in shallow boxes covered with peat or sand.

pests/diseases:

Spider mites, thrips, aphids, dry rot, corm rot and gray mold may occur.

controls:

To control dry rot, corm rot, and gray mold, reduce soil moisture, remove diseased corms or entire plants, and destroy. To control spider mites, thrips, and aphids, use horticultural-oil spray, and hose off aphids with a directed stream of water.

how to sow/plant:

In spring, plant corms 6?8 inches apart and 6?8 inches deep. Begin watering once new growth emerges in spring. Mulch to conserve moisture.

water and fertilize:

Monitor soil moisture all season, watering as needed. Feed biweekly with a balanced, soluble fertilizer, following label directions. After plants flower, stop fertilizing and reduce watering.

garden hint:

It is a good idea to stake all gladioli. Because the flowers at the bottom of the stalk open first, harvest cut flowers early, before these fade. For a continuous supply of cut flowers, plant corms every 2 weeks.
