How to Plant, Grow And Care For Crocosmia ‘Emily McKenzie’
Planting
- Select a planting site that receives full sun to partial shade. Ensure the area has well-drained soil to prevent waterlogging.
- Amend the soil with organic matter, such as compost, to improve drainage and fertility. Aim for a slightly acidic to neutral pH level.
- Plant Crocosmia rhizomes about 3 to 4 inches (7.5 to 10 centimeters) deep and space them 6 to 8 inches (15 to 20 centimeters) apart.
- Plant rhizomes in spring after the threat of frost has passed. This allows them to establish before the growing season.
- Water newly planted rhizomes thoroughly to settle the soil around them. Maintain even moisture until plants become established.
Growing
- Keep the soil evenly moist during the growing season, especially during dry spells. Water deeply but infrequently to encourage deep root growth.
- Apply a balanced, slow-release fertilizer in spring to promote healthy growth and flowering.
- Apply a layer of organic mulch, such as shredded bark or compost, around the base of the plants to conserve moisture, suppress weeds, and regulate soil temperature.
Care
- Remove spent flowers regularly to encourage continuous blooming and prevent self-seeding. This also helps maintain the plant’s appearance.
- Divide overcrowded clumps every few years in early spring or fall to rejuvenate the plants and prevent them from becoming too crowded.
- In colder climates, corms may need winter protection. After the first frost, cut back the dead foliage and apply a layer of mulch (such as shredded leaves or straw) around the base of the plant to insulate the corms. Remove the mulch in spring after the danger of frost has passed.
- Crocosmia is relatively resistant to pests and diseases, but occasional problems such as aphids or spider mites may occur. Monitor plants regularly and treat any issues promptly,
