Planting crocosmias

Ideally, crocosmia is planted in fall or spring for flowering the following summer

  • Plant the crocosmia bulbs 10 cm deep in the sun and where it is hot in summer.
  • The crocosmia likes well-drained soil without being buried too much.
  • Respect a sufficient spacing of 5 to 10 cm between each plant.
  • Let the rhizomes protrude very slightly so that they receive the sun on their upper part.
  • It is more aesthetic to plant the crocosmia in small groups of several bulbs.

Approximately every 3 years it is advisable to divide the stumps by separating the bulbs in order to regenerate the foot.

  • The division is preferably done in the summer
  • Pull the stump out of the ground using a spade
  • Cleanly cut the bulb with a sharp knife
  • Replant the new strain of crocosmia in a suitable place
  • Water generously

Crocosmia seedlings

In sowing, prefer sowing in pot in September-October.

  • You can leave them outdoors and under shelter all winter long.
  • Flowering will only occur 2 to 3 years after sowing.
  • You will proceed with transplanting in the ground as soon as the first leaves emerge.

Caring for Crocosmias

Crocosmia is a perennial that is very easy to maintain and generally does not require any care once it is well established.

  • Regularly weed around so as not to let weeds take over the rhizomes
  • Remove faded flowers as you go but leave the foliage until it turns yellow, usually until September.
    The crocosmia needs to see its leaves turn yellow in order to build up the reserves it needs for the next flowering.
  • Remove weeds that grow in the center of the plant to clear the rhizomes.
  • No need to water because the plant does not need it.

Crocosmia in winter

Whether in a pot or in the ground, the crocosmia resists frost provided that it is neither too strong nor too long.

In the event of a long and vigorous winter, it is imperative to protect your crocosmia bulbs.

  • A good mulch is enough if the temperatures do not drop below -5°
  • It will be necessary to dig up the bulbs and put them away from frost if you fear a strong frost
