Lightly prune your Common rush during the spring and summer by removing wilted, discolored, or diseased leaves. Use sharp and sterile hand pruning shears to make clean cuts. Pruning helps increase light and ventilation for the plant. Some gardeners choose to remove flower buds for aesthetic purposes, but it does not affect the overall health of the plant. After pruning, there is no specific maintenance task to perform, but be careful not to touch the wounds while watering to prevent fungal infections. Placing the plant in a well-ventilated location can help the wounds dry out and heal.
