Pruning mimosa in Mandelieu

Pruning: recommended, every year, especially in windy regions. After flowering, cut branches which have flowered to prevent pods forming unnecessarily. Balance the branch and lighten it by removing poorly placed or redundant branches. Small velvety golden yellow braids (Glomeruli), gathered in bouquets are hung directly on the stem (called "sessiles"). The evergreen light green, sometimes blueish foliage is decorative all year round. Often very light, it is similar to that of some ferns.
