Gladiolus Growing Guide

Planting Gladiolus

  • Plant in spring after the last frost.
  • If you cannot plant your bulbs and perennials right away, store them in a cool, dry, dark location, like a basement.
  • Plant them with the pointy end up in a sunny to semi-shaded area about 13 cm (5 in) deep and 13 to 15 cm (5 to 6 in) apart.
  • Water thoroughly after planting.

Growing Gladiolus

  • Plant Gladioli at biweekly intervals for continuous colour.
  • These bulbs do best in well-drained soil.
  • Gladioli will bloom in 60 to 80 days.
  • Shelter from strong winds.

Care Gladiolus

  • These bulbs are very easy and do not need much fertilizer.
  • Gladioli bloom from the bottom up and they last a long time, about 2 weeks.
  • Stake taller varieties.

Winterizing Gladiolus

  • These bulbs are not winter hardy and need to be dug up after the first frost.
  • Do not wash but dry the bulbs for a day.
  • After you dry the bulbs, place in a paper bag.
  • Store them in a dark and cool location.
