We moved into a house with mature camellias against the east side of the house in the front yard. They are shaded except for about three hours or so. They have not bloomed in the last three years but have grown very tall. Since they had no buds this winter, we cut them back by a third. Needless to say, they're not very attractive. Six weeks or so later they show no sign of growth. We're trying to decide whether they are worth saving, or if we should replace them. Opinions would be much appreciated.
