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!

Planting Gladiolus:

  • 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.

Care:

  • 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.

So now that you know how to plant gladiolus, it’s time to roll up your sleeves and get to planting!

Happy Planting!
