Care Information

  • Plant when danger of frost has passed and the ground has warmed.
  • Plant 2-3 times the depth of the bulb and 15cm/6” apart.
  • In well drained moist soil, in a sunny position.
  • Gladioli prefer to be in spaces where no other plants compete with them.
  • Water regularly as the growth begins to appear.
  • You can hill up the soil when plants are about 15cm/6” tall to help support the stems.
  • Dead head as necessary, but leave foliage.
  • Bulbs will winter in the ground if they are in a warm sheltered position.
  • If exposed and prone to cold conditions Gladioli will benefit from lifting and storing in a frost free location.
  • The smaller or mini varieties of Gladioli, such as nanus or colvillei are in general hardier than the larger variety.
  • Acidanthera, contrary to general belief, is not hardy and needs lifting and storing unless your own experience has proved different.
  • Gladioli can be planted as late as mid-July. It will take between 70-90 days form planting to flowering.
