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

Pruning, maintenance of montbretias

Montbretia, also called Crocosmia, is a perennial bulbous plant that is very easy to care for and generally needs hardly any care when properly established.

  • Weed if necessary around the base so as not to let the weeds take over the rhizomes
  • Remove wilted flowers as you go, but leave the foliage until it turns yellowing, usually until September.
  • Montbretia needs to see its leaves turn yellow in order to build up the reserves it needs for the next flowering.
  • No need to water because the plant does not need it.

Caring for montbretia in winter

Whether in pots or in the ground, montbretia is frost resistant provided it is neither too strong nor too long (around -5 °)

In the event of a long and harsh winter, it is imperative to protect the montbretia bulbs.

  • A good mulching is sufficient if the temperatures do not drop below -5 °
  • You will have to dig up the bulbs and protect them from frost if you fear a severe frost
  • Bring in the pots if your montbretias are grown in pots or containers
