PLANTING and AFTERCARE GUIDE
Best Planting Time
Spring: Plant Hosta ‘Humpback Whale’ in spring when the soil is workable and beginning to warm. This allows the roots to establish before active growth starts.
Early Autumn: Early autumn is also an excellent planting time, giving the root system time to settle before dormancy.
Site Selection
Sunlight: Hosta ‘Humpback Whale’ thrives in partial shade. A position with filtered light or gentle morning sun helps maintain the rich foliage colour and protects the leaves from scorching.
Soil: Moist, fertile, well-drained soil enriched with compost or well-rotted organic matter provides ideal growing conditions.
Planting Instructions
Prepare the Hole: Dig a hole twice the width and the same depth as the root ball so the roots have plenty of room to spread.
Soil Preparation: Mix compost or organic matter into the excavated soil to improve fertility, structure, and moisture retention.
Planting: Position Hosta ‘Humpback Whale’ 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 encourage healthy root establishment.
Watering Requirements
Growing Season: Keep the soil consistently moist during active growth, especially while the plant is establishing.
Dormant Season: Reduce watering once growth slows, but do not allow the soil around Hosta ‘Humpback Whale’ to dry out completely.
Feeding
Spring: Apply a balanced fertiliser in early spring to encourage vigorous foliage growth and healthy flower production.
Mid-Season: A light supplementary feed can help Hosta ‘Humpback Whale’ maintain strong growth throughout the season.
Pruning
Deadheading: Remove faded flower spikes after blooming to keep the plant tidy and direct energy back into the foliage.
Seasonal Care: Remove damaged or faded leaves during the growing season and cut back old foliage once it has naturally died back.
Mulching
Spring: Apply a generous layer of organic mulch around the base to conserve moisture, suppress weeds, and improve soil quality.
Later in the Year: Refresh the mulch when required, keeping it clear of the crown to promote healthy growth.
Supporting the Plant
