FAQs
When does Hydrangea macrophylla 'Early Blue' typically flower?
This variety typically flowers from July to September, often starting weeks earlier than other types of hydrangeas.
How large does this hydrangea grow?
It reaches a mature height and spread of approximately 120cm (48 inches).
Can I grow this in a pot?
Yes, it is well-suited for large patio containers. Use ericaceous compost to help maintain blue flower color.
How do I ensure my flowers are blue?
Plant in acidic soil or use ericaceous compost. Soil pH significantly impacts flower color; alkaline conditions will turn blooms pink.
Will the flowers stay blue all season?
The blue color is most intense in acidic conditions. As the season progresses, or if soil conditions change, the blue may fade and transition towards pink, especially in autumn.
What is the benefit of the seedheads in winter?
The dried, skeletal seedheads provide architectural interest and structure to the winter garden, offering visual appeal even after flowering has finished.
How should I prune this plant?
Minimal pruning is usually needed. Remove faded blooms in late winter or early spring and lightly trim to shape if necessary.
Troubleshooting
Flower color is not blue
The soil pH may be too alkaline. Try planting in ericaceous compost or use a hydrangea colorant designed to promote blue flowers. Ensure the plant is in a location with acidic soil.
Plant appears wilted
Check for adequate watering. Hydrangeas require consistent moisture, especially during hot weather or if newly planted. Ensure the soil is not waterlogged, which can also cause wilting.
Limited flowering
Ensure the plant receives adequate sunlight (partial shade to full sun) and is not competing with larger plants for resources. Prune lightly in spring to encourage new growth and blooms.
Leaves turning yellow
This can indicate a lack of nutrients or incorrect soil pH. Consider feeding with a balanced fertilizer or an ericaceous feed if a blue color is desired and soil is not naturally acidic.

Setup, Compatibility & Care
Planting:
This Hydrangea is supplied as a pot-grown plant in a 10.5cm nursery pot. Choose a location with partial shade or full sun, ensuring the soil is well-drained. For the best blue color, plant in acidic soil or use ericaceous compost in containers. If planting in a border, dig a hole twice the size of the root ball and incorporate compost.
Watering:
Water regularly, especially during dry spells, to keep the soil consistently moist but not waterlogged. Newly planted shrubs will benefit from consistent watering during their first year.
Feeding:
Feed in spring with a balanced fertilizer. For enhanced blue color, use a fertilizer specifically formulated for acid-loving plants or hydrangeas that promote blue blooms.
Pruning:
Generally, minimal pruning is required. Remove dead or faded flower heads in late winter or early spring. Prune lightly to shape the plant if necessary, cutting back to strong buds.
Compatibility:
Suitable for garden borders, mixed shrub plantings, and large patio containers. Ensure container size is adequate for mature growth (at least 40-50cm diameter).
