Princess Flower Bush – also called purple princess flower…

Question

How do I prune for best growth? Mine is getting big. There are flowers on the outside edges but the middle is pretty barren.

Hello,

Thank you for sending us your gardening question. Pruning is part of regular tibouchina care. Remove flowers after they fade, to encourage the shrub to continue blooming rather than using its energy to produce seed. Use a pair of pruning shears to cut the flowers off below the spent blooms, just above a set of leaves.
Prune lightly in the late winter or early spring when the leaf buds begin to swell. Prune to improve the plant’s shape and reduce its size. Select tall and misshapen branches and cut back to a parent stem, which is the larger branch from which it originates. Also, thin out crowded areas, especially in the center of the plant. A good rule of thumb to follow is never prune or thin out more than one-third of the shrub each year. Cut damaged and diseased branches back to the parent stem or just above a leaf bud. Do this type of pruning any time of the year, as necessary.
