  • water dropWater

    The Montbretia requires consistent moisture, especially during the growing season. It should be watered deeply once a week, providing about 1 inch of water each time. Ensure the soil is well-draining to prevent waterlogging. During dry spells or in particularly hot climates, you might need to water twice a week, keeping the soil consistently moist but not soggy. Reduce watering in the winter when the plant is dormant, scaling back to when the top inch of the soil feels dry to the touch.

  • sunLight

    Montbretia thrives in full sunlight but can tolerate partial shade. The ideal spot for this plant is one where it can receive at least six to eight hours of direct sunlight daily. Areas with morning sunlight and afternoon shade can also be suitable, especially in hotter climates to protect from the scorch of the midday sun.

  • thermometerTemperature

    Montbretia performs well in a temperate climate and can tolerate a temperature range from 40°F to 90°F. They prefer an ideal temperature around 60°F to 70°F. It's important that the temperatures do not consistently drop below 40°F, as this can damage or kill the plant.

  • scissorsPruning

    Prune Montbretia to remove spent flowers and to keep the plant looking tidy, as well as to encourage additional blooming. You can also cut back the foliage in the fall once it has died back naturally. Pruning is typically only needed once a year, with the best time being late fall or early winter after the plant has finished blooming and the foliage has yellowed.

  • circleLife cycle

    The life cycle of Crocosmia 'Comet', commonly known as Montbretia, begins when its corms are planted in the soil in late winter or early spring. The corms germinate and produce sword-shaped leaves, followed by the development of long, arching flowering stems in summer, which bear vibrant, funnel-shaped flowers that attract pollinators such as bees and hummingbirds. After flowering, the plant sets seed pods, which eventually dry and release seeds, although reproduction is primarily through division of the corms. In autumn, the foliage begins to die back as the plant enters dormancy, reserving energy in the corms for the next growth cycle. Throughout winter, the corms overwinter underground, and with the return of warmer temperatures in the following spring, the cycle recommences with the sprouting of new growth. Montbretia spreads and naturalizes over time, with the corms multiplying to form larger clumps that require division every 3-4 years to maintain plant vigor.

    • Propogation time

      Late spring

    • Propogation: The Crocosmia 'Comet' Knutty, commonly known as Comet Crocosmia, is typically propagated through the division of corms. The best time to propagate this plant is in the spring after the threat of frost has passed. To propagate by division, carefully dig up the clumps of Crocosmia corms and gently separate them by hand, ensuring that each new clump has at least one growing point or shoot. These can then be replanted immediately at a depth of about 3 to 5 inches (approximately 7.5 to 12.5 cm) and spaced approximately 6 to 8 inches (about 15 to 20 cm) apart. Water the newly planted corms well to establish them. Through this method, the Comet Crocosmia will rapidly develop new shoots and roots, and by the end of the growing season, each individual corm should have multiplied, providing more plants for future growth or sharing with fellow gardeners.
