PLANTING and AFTERCARE GUIDE
Best Planting Time
Spring: Plant Astilbe ‘Mighty Chocolate Cherry’ in early spring when the soil becomes workable. This timing allows for root establishment before the flowering period.
Autumn: Planting in early autumn is also suitable. It gives the roots time to settle before winter, leading to stronger growth in the next season.
Site Selection
Sunlight: Astilbe ‘Mighty Chocolate Cherry’ performs best in partial shade, though it can tolerate full sun if the soil remains consistently moist.
Soil: Choose moist, well-drained, humus-rich soil. Astilbe prefers slightly acidic to neutral conditions. Improve drainage and nutrition by incorporating compost or leaf mould.
Planting Instructions
Prepare the Hole: Dig a hole twice as wide as the root ball and about the same depth.
Soil Preparation: Mix in plenty of organic matter to enrich the soil and retain moisture. This is crucial for Astilbe ‘Mighty Chocolate Cherry’, which does not tolerate dry conditions.
Planting: Position the plant with the crown just at soil level. Backfill gently and firm the soil to eliminate air pockets.
Watering After Planting: Water thoroughly to help settle the plant in. Consistent watering is essential for Astilbe, especially in the first growing season.
Watering Requirements
Growing Season: Astilbe ‘Mighty Chocolate Cherry’ needs consistently moist soil. Water during dry spells, especially when flower spikes are forming.
Dormant Season: Reduce watering in late autumn and winter unless conditions are particularly dry. Moist but not soggy soil helps prevent root rot.
Feeding
Spring: Apply a balanced, slow-release fertiliser in early spring to support healthy foliage and flower spike development.
Mid-Summer: A light application of fertiliser during the blooming period can enhance colour intensity and prolong flowering.
Pruning
Deadheading: Once the flowers fade, cut back the stems to promote tidy growth. While not essential, it can improve the plant’s overall appearance.
Autumn Pruning: In late autumn, cut foliage back to just above ground level. This prepares Astilbe ‘Mighty Chocolate Cherry’ for winter dormancy and encourages strong regrowth in spring.
Mulching
Spring: Apply a generous mulch of compost or well-rotted organic material in spring to lock in moisture and suppress weeds.
Winter: Add a protective mulch layer in winter to insulate the roots and help the plant survive cold snaps.
Supporting the Plant
Astilbe ‘Mighty Chocolate Cherry’ generally maintains an upright growth habit. However, in exposed spots, consider staking the tall flower stems to prevent wind damage during peak bloom.
