PLANTING and AFTERCARE GUIDE
Best Planting Time
Spring: Plant Veronica longifolia ‘Alba’ in spring when the soil is workable and beginning to warm, allowing roots to establish before active growth.
Early Autumn: Early autumn is also an excellent time to plant, giving the root system time to settle before dormancy.
Site Selection
Sunlight: Veronica longifolia ‘Alba’ thrives in full sun or partial shade. A bright position encourages sturdy stems and an abundance of flowers.
Soil: Moist, fertile, well-drained soil is ideal. Incorporate compost or well-rotted organic matter before planting to improve soil structure and moisture retention.
Planting Instructions
Prepare the Hole: Dig a hole twice the width and the same depth as the root ball to allow the roots to spread comfortably.
Soil Preparation: Mix compost or organic matter into the excavated soil to improve fertility while maintaining good drainage.
Planting: Position the plant with the top of the root ball level with the surrounding soil, then backfill gently and firm lightly.
Watering After Planting: Water thoroughly after planting to settle the soil and help Veronica longifolia ‘Alba’ establish quickly.
Watering Requirements
Growing Season: Keep the soil evenly moist during active growth, especially while the plant is becoming established.
Dormant Season: Reduce watering once growth slows, although the soil around Veronica longifolia ‘Alba’ should not be allowed to dry out completely for extended periods.
Feeding
Spring: Apply a balanced fertiliser in early spring to encourage healthy foliage and prolific flowering.
Mid-Season: A light supplementary feed during the flowering period will help Veronica longifolia ‘Alba’ maintain strong growth and continued blooms.
Pruning
Deadheading: Remove faded flower spikes regularly to encourage a tidy appearance and extend the flowering season.
Seasonal Care: Cut back old stems after flowering or in late autumn to encourage healthy new growth the following season.
Mulching
Spring: Apply a layer of organic mulch around the base to retain moisture, suppress weeds, and improve soil quality.
Later in the Year: Replenish mulch as needed, keeping it clear of the crown to prevent excess moisture around the base.
Supporting the Plant
Natural Habit: Taller stems may benefit from discreet support in exposed locations. Positioning plants among neighbouring perennials can also provide natural stability.
