Should I cut back limelight hydrangeas in the fall?

Lorraine Ballato, author of Success with Hydrangeas, suggests that pruning limelight hydrangeas in late fall, winter, or early spring is recommended due to the plant’s dormant state. This is because the plant develops its flower buds on new growth, and pruning can be done before the plant sets its buds for the following summer. However, in severe winter climates with temperatures regularly below freezing, it is best to wait until spring to allow for winter kill, which can reduce the hydrangea’s size naturally. Pruning after the plant has naturally dropped its leaves offers advantages such as a better view of the plant’s shape and easier access to all branches for clean pruning cuts.

What are the conditions for limelight hydrangeas?

Why is my limelight hydrangea dying?

Trudy, your hydrangeas are suffering from a root rot disorder, specifically in quercifolia and paniculata types. This can be caused by the plant drying out, absorbing too much water, causing roots to burst, and soil fungi entering through the burst roots. Despite the potential for root rot diseases, there is little that can be done once they take hold. To combat this, you can use beneficial soil fungi like trichoderma or soil drenches, which can be found at local garden centers.

Poorly drained soils, such as heavy clay, can also cause root rot. If you choose to treat the plant, cut it back to 50cm from ground level, remove the flowers and dead leaves, burn all plant material or dispose of it in the rubbish, and treat with a soil drench. Clean all cutting tools after cutting back the diseased foliage. However, leaving the plant in the ground and treating it raises the risk of the disease spreading to other healthy plants. To prevent further infection, dig out the surrounding soil and replace it with fresh soil or potting mix.
