Nandina domestica has the habit of bearing fruit every other year. After fruiting, pruning is carried out in February-March, and useless branches are cut off from the base, leaving 3-5 strong branches as the trunk. You can also use the form of ramets to reduce the number of dry plants. When the trunk is too long from March to June, the main tip can be cut off from the branch. Usually, the branchlets sprouting at the roots should be cut off in time to help the trunk thicken. Cut the inflorescence dry after fruit dropping every year to keep the plant clean. It is also necessary to cut off old branches and crowded branches to facilitate ventilation and light transmission in the crown. If you want to grow small branches on the trunk, you can cut off the tip of the petiole to promote the growth of branches.
