Thompson & Morgan Hydrangea Early Blue - 10.5Cm Pot X 2

The best time to plant is in spring or early autumn, allowing the roots to establish before extreme weather conditions.

To achieve and maintain deep blue flowers, use a hydrangea colorant or fertilize with a product that acidifies the soil. Consistent application from early spring is recommended.

Yes, Hydrangea macrophylla 'Early Blue' can be grown successfully in a large pot, provided it has good drainage and consistent watering.

The mature height and spread are approximately 120cm (around 4 feet).

Prune in late spring after the last frost. Focus on removing dead or damaged wood. Avoid heavy pruning to preserve the old wood that produces flowers.

It prefers moist, well-drained soil. For blue flowers, the soil should be slightly acidic. Adding compost or organic matter improves soil structure.

The blue color is most intense when the soil conditions are right. As autumn approaches, the flowers may naturally fade to pink, or their color may shift depending on soil pH.

This is often due to soil pH. For bluer flowers, use a hydrangea colorant or a fertilizer that acidifies the soil. Ensure the soil is not too alkaline.

Check the soil moisture. Hydrangeas need consistent watering. Ensure the plant is not in excessively hot, direct sun without adequate hydration. Check for pests or root issues if watering is adequate.

Ensure the plant is mature enough to flower. Pruning at the wrong time (e.g., late winter or spring) can remove the previous year's wood where flower buds form. This variety blooms on old wood, so avoid heavy pruning in spring.

This can be caused by too much direct sun, strong winds, or underwatering. Move the plant to a location with more shade or ensure consistent watering and wind protection.
