Do crocosmia like sun or shade?
Crocosmia corms prefer to be planted in humus-rich, moist but well-drained soil, but they’re pretty tolerant of most soils as long as it’s not too dry. Although a sunny position is preferable, and indeed flowers will be more prolific in full sun, crocosmia will grow perfectly well in partial shade. Where to plant. Crocosmias will grow in a wide range of soil types, but ideally prefer a warm, sunny spot in fertile, moist but well-drained soil. Some will cope in light shade, but flowering may be reduced. Avoid planting in waterlogged or very dry conditions, or in deep shade.Aftercare. Water your crocosmias once weekly during the growing season so the soil remains evenly moist. Remove spent blooms to encourage new blooms. Cut the stems back to where they meet the leaves.Plant your Crocosmia corms in the spring after the danger of frost has passed. If the weather conditions are still chilly or the soil temperature is cold, hold off planting until the soil has warmed up.How to Grow Crocosmia. Sow these seeds into trays or small pots filled with a seed starter mix. Sow 4-5 seeds per plant at a depth of 1/4 inch, and lightly cover.Crocosmias will grow in a wide range of soil types, but ideally prefer a warm, sunny spot in fertile, moist but well-drained soil.

They radiate beautifully with Heleniums (Sneezeweed), Kniphofias (Red Hot Pokers), Dahlias, and ornamental grasses, maintaining the interest well after the first leaves fall.From mid-summer through mid-fall, Crocosmia produces clusters of tubular flowers along its long, arching stems.

It has the longest blooming season of all our crocosmias, too, remaining in bloom for weeks.Many crocosmias make good cut flowers and ‘Lucifer ‘ is the best for its tall, strong stems and rigidly branched flower heads. The big bonus is that it is at its best when the flowers have faded and you are left with the seed heads.Grow crocosmia in moist but well-drained soil in full sun to partial shade. Divide congested clumps every three to five years to rejuvenate them and encourage better flowering. In colder regions you may need to mulch the corms to protect them from frost.
How hardy is crocosmia?
Zone: Crocosmias are winter hardy in zones 6-9. The bright red cultivar ‘Lucifer’ will survive winters in zones 4 and 5. If you are concerned about hardiness, treat crocosmia as you would gladiolus. Dig the bulbs up after the first light frost and store them indoors for winter. Crocosmia corms should be planted in spring after all danger of frost is gone. If conditions are cool or the soil temperature is cold, delay the planting until the soil has warmed up.Compact crocosmia varieties can be potted up from containers in which they came as potted plants, or planted as dormant corms in spring.Crocosmia corms prefer to be planted in humus-rich, moist but well-drained soil, but they’re pretty tolerant of most soils as long as it’s not too dry. Although a sunny position is preferable, and indeed flowers will be more prolific in full sun, crocosmia will grow perfectly well in partial shade.Crocosmia is a bold, summer-blooming perennial known for its arching stems lined with tubular, fiery-hued flowers that attract hummingbirds and butterflies. Native to South Africa, this plant adds vibrant energy to sunny gardens with shades of red, orange, and yellow.However, one notable exception is Crocosmia. Despite its tropical origin, this vigorous perennial is hardy down to zone 5 and can stay in the ground year-round in all but the harshest climates, reliably blooming season after season.
Will crocosmia multiply?
Crocosmia corms multiply each year and clumps can become congested, leading to reduced flowering and vigour. Established plants can be lifted and divided every 3 to 4 years. Carefully separate the corms and replant the top-most corms, which will produce vigorous plants for the coming season. Crocosmia can be propagated by division in spring or autumn after flowering. Crocosmias flower profusely when crowded so do not divide clumps too often. Dividing every two or three years will be sufficient.There is no need to deadhead crocosmia flowers after they bloom. They will rebloom on their own.Deadhead crocosmias regularly to encourage new blooms. Cut the stem back where they meet the leaves. Be sure to keep the leaves of a crocosmia after the flower has finished blooming, as they can be reused to provide an energy charge to the bulb through photosynthesis.Once exposed to full sun again, Crocosmia should return to flower. You may also have chosen a spot which does not provide the moist but free-draining, fertile soil conditions that these plants require. Transplanting to a more suitable spot, or amending the soil with plenty of organic matter, could solve this problem.

Divide congested clumps every three to five years to rejuvenate them and encourage better flowering. In colder regions you may need to mulch the corms to protect them from frost.Common montbretia (Crocosmia × crocosmiiflora) has ‘escaped’ from gardens into the wild, where it can crowd out more delicate native species.
