Planting and growing gladiolus, gladiolus is a parennial favered for its beautiful, showy flowers. Its flowers grow on tall spikes and are often found in cutting gardens or in the back along the border (because they are tall). Gladioli have many different colored flowers, and grow between 2 to 6 feet in height. It’s good for cut flowers.Before the first frost, you can dig up glads to store over the winter.
Planting And Growing Gladiolus
- Plant gladiolus bulbs in the spring once danger of frost has passed and the soil has warmed.
- Ready your garden by using a garden fork or tiller and loosen the soil to about 12 to 15 inches deep. After loosening the soil, mix in a 2– to 4–inch layer of compost.
- Set the corm in the hole about 4 inches deep with the pointed end facing up. Cover with soil and press firmly.
- Space the corms 3 to 6 inches apart. Water the corms thoroughly.
- Gladioli like well-drained, light soil and full sun.
- If you’re planting tall varieties, be sure to stake them at planting time. Be careful not to damage the corms with the stakes.
- It takes about 90 days from the time gladioli are planted to root, grow, bloom, and store enough energy for the next season.
Care of planting and growing gladiolus
- Put a 2– to 4–inch layer of mulch around your gladioli to keep your soil moist and help prevent weeds.
- If you get less than 1 inch of rain a week, water your plants regularly throughout the summer. Otherwise, water them moderately when in growth to keep the soil moist.
- Remove the faded/dead flowers to ensure continuous growth. Once all the flowers on a stalk have gone, cut off the stalk.
- Be sure to leave the plant intact so it can mature and rejuvenate the corms for the next season.
- If you live in zones 7 or 8, put down a layer of hay or straw for winter protection.
- Corms should be dug before the first frost if you live in zone 7 or ones colder. See instructions below.

Harvest/Storage plant of Gladiolus
- Use a space and dig up cothe entire plant, grasping the top to pull it out of the soil. Avoid bruising or injuring corms while digging. Shake off all loose soil and discard damaged corms. Cut the stalk within 1 inch above the corm. Save the small cormels separately if you so desire.
- Allow the corms to dry in the Sun for 1 or 2 days if the weather agrees. Sift out excess soil and place corms in wooden flats or trays. Cure ina warm and airy location for 2 weeks (at a temperature of 80-85°F). Remove and throw away the oldest bottom corms (from the base of the new one).
- Dust freshly dug, clean corms with a fungicide (“bulb dust”) to avoid disease problems. Place dust and bulbs or other structures in a paper sack and shake vigorously.
- Store the large, new corms in paper boxes, open paper bags, cloth bags, wooden trays with screen bottoms, or old onion sacks. Stack or hang the containers so air can move among them. Store the corms at 35 to 45°F in low humidity. A cool basement is quite suitable. Do not allow corms to freeze.
- Replant these corms in the spring for another year of beautiful blooms.
