A L N U S ... G L U T I N O S A Grown from seedling found in 1983 75cm high - 63cm wide Pot: David Jones at Walsall Studio Being a waterside treee, Alder need wet roots so I stand the pot in a large 'suiban' (water tray) and keep it in full sun all day. Even with moderate feeding, this results in very vigorous and dense growth which is hard work to control. This photograph was taken two weeks after total defoliation.
