PLANTING and AFTERCARE GUIDE
Best Planting Time
Spring: The best time to plant Crocosmia ‘Suzanna’ is in spring when the soil begins to warm. This allows the corms to establish strong roots before flowering in late summer.
Autumn: Alternatively, plant Crocosmia ‘Suzanna’ in early autumn to give the roots time to settle before dormancy, ensuring vigorous growth in the following season.
Site Selection
Sunlight: Crocosmia ‘Suzanna’ flourishes in full sun to partial shade. Choose a planting site that receives at least 6 hours of direct sunlight per day for optimal blooming.
Soil: Well-drained soil is essential for Crocosmia ‘Suzanna’ to prevent waterlogging and root rot. Improve soil quality by incorporating organic matter such as compost to enhance drainage and fertility.
Planting Instructions
Prepare the Hole: Dig a hole about 8-10cm deep and space the corms 10-15cm apart to allow for spreading.
Soil Preparation: Mix organic compost or well-rotted manure into the soil to improve drainage and encourage healthy growth.
Planting: Place the corms in the hole with their pointed ends facing upwards. Cover with soil and gently firm down.
Watering After Planting: Water thoroughly after planting to help the corms settle and promote root establishment.
Watering Requirements
Growing Season: Once established, Crocosmia ‘Suzanna’ is relatively drought-tolerant. Water during prolonged dry spells, but allow the soil to dry slightly between watering sessions.
Dormant Season: Reduce watering in autumn and winter when the plant enters dormancy, only providing moisture if the soil becomes excessively dry.
Feeding
Spring: Apply a balanced fertiliser in early spring to support strong new growth and encourage abundant flowering.
Mid-Summer: A light feed in mid-summer can help sustain the plant’s energy and prolong the blooming period of Crocosmia ‘Suzanna’.
Pruning
Deadheading: Regularly remove spent flowers to keep Crocosmia ‘Suzanna’ looking tidy and to encourage continuous blooming.
Autumn Pruning: After flowering has finished, cut back the foliage to ground level to prepare the plant for winter dormancy.
Mulching
Spring: Apply a layer of mulch in spring to help retain soil moisture, suppress weeds, and maintain an even soil temperature.
Winter: A protective layer of mulch around the base of Crocosmia ‘Suzanna’ in winter helps insulate the corms from cold temperatures and frost.
Supporting the Plant
Staking: Although Crocosmia ‘Suzanna’ has sturdy stems, it may benefit from light staking in particularly exposed or windy locations to prevent bending.
