Pruning during late winter helps 'three-leaf derris' enter its growing season without the burden of extra limbs, dead wood, and excess foliage that can drain its energy. This timing also prevents cutting off new buds that will flourish in spring. Early spring pruning is also advantageous as it allows gardeners to clearly see the structure of 'three-leaf derris' before the full leaf-out, ensuring precise cuts that promote healthy growth and plant shape.
