Before starting, observe your plant’s natural growth habit. Tibouchina urvilleana typically grows in an upright, bushy manner with potentially wide-spreading branches. Knowing the natural form will help you decide which branches to cut in order to encourage a fuller rounded shape. Look for stems that have finished flowering or are growing out of bounds. Use clean, sharp pruning shears to make cuts at a 45-degree angle, just above a set of leaves or side growth. This will encourage the plant to heal quickly and direct nutrients effectively to these points for bushier growth. When pruning, focus on achieving balance and symmetry in your Tibouchina bush. Aim for an even distribution of branches by trimming more where growth is denser. This will help optimize light penetration and air circulation, which are critical for healthy growth and reducing the risk of disease. More About Pruning Techniques→
