PLANTING and AFTERCARE GUIDE
Best Planting Time
Plant Allium ‘Silver Spring’ when the soil is cool yet workable. During this stage, bulbs can settle gradually and, as a result, establish strong roots ahead of active growth and flowering in mid to late summer.
Site Selection
Sunlight: Choose a position in full sun. Adequate light, therefore, supports strong stems and well-defined flower heads on Allium ‘Silver Spring’.
Soil: Well-drained soil is essential. Improve heavier soils with grit or sand, as free drainage prevents bulb rot and promotes healthy growth.
Planting Instructions
Prepare the Hole: Dig a hole around three times the depth of the bulb to provide stability and protection.
Soil Preparation: Loosen the soil and incorporate grit to enhance drainage and airflow.
Planting: Place the bulb with the pointed end facing upwards, then gently backfill and firm the soil.
Water After Planting: Water lightly to settle the soil and encourage early root development for Allium ‘Silver Spring’.
Watering Requirements
Growing Season: Water sparingly, allowing the soil to dry slightly between watering sessions. Consequently, this avoids excess moisture around the bulbs.
Dormant Period: Once foliage dies back, reduce watering significantly, as Allium ‘Silver Spring’ prefers drier conditions while dormant.
Feeding
Early Growth: Apply a light, balanced fertiliser as shoots emerge to support stem strength and flower development.
After Flowering: Feeding after blooming helps replenish the bulb and prepares Allium ‘Silver Spring’ for the following season.
Pruning and Maintenance
Deadheading: Remove spent flower heads to maintain a tidy appearance, although dried seed heads can be left for architectural interest.
Foliage Care: Allow foliage to die back naturally, as this process feeds Allium ‘Silver Spring’ for next year’s display.
Mulching
Spring Mulch: Apply a light, free-draining mulch to suppress weeds and improve soil structure.
Protective Mulch: Keep mulch minimal to prevent excess moisture building up around the bulbs.
Final Tips
Allium ‘Silver Spring’ is a hardy, low-maintenance perennial best planted where its elegant flowers can be fully appreciated. With good drainage, minimal watering, and occasional feeding, Allium ‘Silver Spring’ will return reliably each year with striking summer blooms.
