Gladiolus is a classic perennial flower that grows tall flower spikes and that’s great for cutting. Available in a slew of different colors, gladioli can grow between 2-6 feet tall. The taller versions are usually planted in the back of the garden and staked to compliment flowers in the front. In zones 7 and colder though, gladioli will need to be lifted and replanted again in the spring. Keep reading to find out how to plant gladiolus in your garden and get a beautiful garden full of flowers!
How to Plant Gladiolus in Your Garden
- Plant gladiolus bulbs in the spring once all danger of frost has passed.
- Choose a spot with full sun.
- Loosen the soil to 12-15 inches deep. Mix in a 2-4 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.
- Set each corm 3-6 inches apart and water them thoroughly.
- If you’re planting the tall variety, make sure to set a stake next to the corm at planting time.
- It will take about 90 days for the gladioli to bloom.
- Cover the soil with 2-4 inches of mulch to keep gladioli moist.
- Keep soil moist at all times, and water regularly.
- Remove faded and dead flowers to ensure continuous growth.
- Once all the flowers on the stalk are gone, cut down the stalk.
- If you live in USDA zones 7 and 8, lay down a layer of mulch to protect the plants in the wintertime.
