Grey Alder hedging will grow in almost all moist soil and can tolerate both full sun and partial shade.

Grey Alder can be planted from November to March, when the hedge is dormant. Ensure that the area where you are going to plant the hedge is clear and weed-free.

Caring and Maintenance

Cut back plants to 15-30cm (6in-1ft) on planting. In first summer trim side branches lightly to encourage bushing out. In the second year (February to March) cut back growth by half. Throughout the second summer trim side branches to maintain sides that taper towards the top. In the second autumn cut the topmost branch (‘leading shoot’) to the desired hedge height. Trim every June after that.

Can be maintained at over 180cm (6ft).
