How to take care of Hydrangea arborescens Annabelle 14 cm
Hydrangeas require a moisture retentive soil that is enriched with organic matter such as peat. Thrives best in partial shade. Choose a sheltered position against a wall or under a tree but avoid hedges. Protect against severe frost in winter. Do not remove dead flower-heads, leave them on through the winter as they help protect the plant from frost. They may be pruned immediately after blooming as flower buds are formed on previous seasons growth to maintain a specific height. In spring, feed established plants with a fertiliser and apply a thick layer of mulch for protection of the roots. Colour is due to the soil pH, which affects aluminium availability. Plants with blue or pink flowers tend to be blue in acid soil conditions high in aluminium, mauve in acid to neutral soil, and pink in alkaline soil. Water plants with rainwater if possible, since mains hard water can affect the flower colour, turning blue flowers mauve or pink. In colder regions, flower buds may freeze without protection.
