Is montbretia the same as crocosmia?
Answer: Montbretia is the common name used for a wonderful and reliable summer flowering bulb called crocosmia. The problem you are having is common. The primary solution is to thin out the planting. Crocosmia is a very vigorous, fast growing bulb that reproduces and spreads rapidly.
How do you look after crocosmia UK?
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.
Where does crocosmia grow best?
Crocosmia will survive in part shade but best flower production is obtained in full sun – except in hot summer climates where part shade will enable the flowers to last longer. Plant in fertile, humus-rich, moist but well-drained soil. Crocosmia do not enjoy hot, dry sites.
How do you overwinter crocosmia?
Because they are more cold hardy than other summer-blooming bulbs, you can usually leave them in the ground over winter. Cover them with a layer of mulch to insulate them from severe cold snaps. However, if you live in Zone 4 or below, lift the corms, store them in a cool, dry location, and replant them in the spring.
Why does my montbretia not flower?
Crocosmia (also called Monbretia or Copper tips) is a perennial plant that flowers from around July until September with a good 8 weeks of blooms from established plants. If your crocosmia is not flowering this is usually because of too much fertilizer, water stress or not enough sun.
Do crocosmia come back each year?
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.
Is it too late to plant crocosmia bulbs?
when to plant crocosmia Plant crocosmia corms in early spring and young plants in late-spring to early summer.
Can you plant crocosmia bulbs in pots?

Will Montbretia grow in shade?
