Crocosmias prefer slightly acidic soil. Make sure the garden bed is nutrient rich and well-drained, but lightly moist. Plant the corms in spring about 6 to 8 inches apart at a depth of 3 to 5 inches. Plant them in clusters for maximum effect.
Moreover, which way up do you plant Crocosmia bulbs?
Crocosmia corms are swollen underground stems that store food for the plant. They reproduce rapidly and often will be found in large clumps. To separate the corms, just twist them apart. When planting, place each corm 2 inches deep and 3 inches apart with the “bull’s-eye” mark facing up.
Subsequently, question is, how long does it take for crocosmia to sprout? Water well to settle the soil around the corms. A light mulch that helps hold soil moisture, but does not lean against the stems (can promote stem rot) is often helpful. Crocosmia corms can take 3-5+ weeks to begin to sprout depending on soil temperature and moisture levels.
Correspondingly, how do you divide Crocosmia corms?
How to Split a Crocosmia
- Loosen the soil to a 12-inch depth around the crocosmia clump with a trowel or handheld garden fork, but avoid piercing the corms as you work.
- Rinse the roots off with a gentle stream of water so the corms are easily visible.
- Work a 2-inch layer of compost into the top 6 inches of the garden bed with the trowel.
When can I move Crocosmia bulbs?
Transplant during the dormant season, late fall through early spring. In early spring, wait until the first young green shoots appear in the spring to see where new growth is occurring.
