PLANTING and AFTERCARE GUIDE
Best Planting Time
Spring: The ideal time to plant Astilbe simplicifolia ‘Pretty in Pink’ is in spring when the soil is workable and warming up. This encourages strong root development before flowering begins.
Autumn: Planting in early autumn also works well, allowing the plant to establish ahead of its next active growing season.
Site Selection
Sunlight: Astilbe simplicifolia ‘Pretty in Pink’ performs best in partial shade but can tolerate full sun if the soil remains consistently moist.
Soil: Choose moist, well-drained soil enriched with organic matter. Avoid dry or sandy locations, as this variety prefers cool, moisture-retentive conditions.
Planting Instructions
Prepare the Hole: Dig a hole twice as wide as the root ball and equal in depth.
Improve the Soil: Mix compost or well-rotted manure into the excavated soil to boost moisture retention and nutrients.
Planting: Position Astilbe simplicifolia ‘Pretty in Pink’ so the crown is level with the soil surface. Fill in with soil and gently firm down.
Water Thoroughly: Water well after planting to settle the soil around the roots.
Watering Requirements
During dry spells, especially in the summer months, keep the soil evenly moist. Astilbe simplicifolia ‘Pretty in Pink’ dislikes drying out, particularly while blooming.
Apply water at the base of the plant to avoid mildew or rot on the foliage.
Feeding
Apply a balanced, slow-release fertiliser in spring to encourage healthy foliage and flower production.
For continued vigour, top-dress with compost or organic mulch annually.
Pruning
Deadhead spent flower spikes to tidy the plant and encourage new blooms.
After flowering, the foliage can be left to die back naturally. Cut it back in late autumn or early spring before new shoots emerge.
Mulching
Apply a generous layer of mulch around the base of Astilbe simplicifolia ‘Pretty in Pink’ in spring. This helps retain moisture, suppress weeds, and regulate soil temperature.
Refresh mulch annually to support ongoing health.
Supporting the Plant
This compact variety typically requires no staking, but in exposed areas, a light support may help prevent damage from wind or heavy rain.
