It is also a way of regular maintenance that Crocosmia is kept healthy and attractive during the growing season. After flowers are already blooming, remove them when they are old to ensure the plant looks neat and promote new flowers. When the season is over, just leave the foliage to turn yellow and cut-off, this is to enable the plant to save some energy to be used the following year. In regions with lower temperatures, a mulch can be used to cover the corms against winter frost.
