PLANTING and AFTERCARE GUIDE

Best Planting Time

• Spring: Plant Erigeron glaucus ‘Olga’ 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 ideal time for planting, giving the root system time to settle before dormancy.

Site Selection

• Sunlight: Erigeron glaucus ‘Olga’ thrives in full sun, where it will produce the best flowering display.
• Soil: Moist, well-drained soil is ideal. Improve the planting area with compost or well-rotted organic matter to enhance soil structure while maintaining good drainage.

Planting Instructions

1. Prepare the Hole: Dig a hole twice the width and the same depth as the root ball to give the roots room to spread.
2. Soil Preparation: Mix compost or organic matter into the excavated soil before planting.
3. Planting: Position Erigeron glaucus ‘Olga’ so the top of the root ball sits level with the surrounding soil surface, then backfill gently and firm lightly.
4. Watering After Planting: Water thoroughly after planting to settle the soil and encourage strong root establishment.

Watering Requirements

• Growing Season: Water regularly while the plant is establishing and during prolonged dry periods, keeping the soil evenly moist without becoming waterlogged.
• Established Plants: Once established, Erigeron glaucus ‘Olga’ is relatively drought tolerant but benefits from occasional deep watering during extended dry spells.

Feeding

• Spring: Apply a balanced fertiliser in early spring to encourage healthy foliage and prolific flowering.
• Mid-Season: A light supplementary feed can help Erigeron glaucus ‘Olga’ maintain its long flowering display through summer.

Pruning

• Deadheading: Remove faded flowers regularly to encourage continuous blooming and keep the plant looking neat.
• Seasonal Care: Trim back any tired or damaged growth after flowering to maintain a compact, tidy shape.

Mulching

• Spring: Apply a light layer of organic mulch around the base to retain moisture, suppress weeds, and improve soil quality.
• Later in the Year: Refresh mulch as needed to support healthy root development and consistent soil conditions.

Supporting the Plant

• Natural Habit: Erigeron glaucus ‘Olga’ has a naturally compact, low-growing habit and does not require staking or additional support.
