My hedge is dieing from one end and I don't know how to stop it.
Welcome to the Bunnings Workshop community @loumoat. It's wonderful to have you join us and many thanks for you question on plant care.
From your photos, it looks like the hedge is suffering from dieback starting at one end, with brown, dry branches and some areas that are still green and healthy. There are a few common causes for this kind of problem. Water stress can occur if one end of the hedge is receiving less water due to uneven irrigation or if the soil dries out faster on that side, causing the plants to start dying back. Root damage or disease, such as fungal infections or root rot, can also lead to dieback, so inspect the base of the plants for soft, discoloured roots or any signs of fungal growth. Nutrient deficiency may be another factor, especially if the soil is poorer at one end; applying a general-purpose fertiliser suitable for hedges can help restore vigour. Additionally, sun exposure and wind can dry out one end more quickly, causing browning; mulching around the base helps retain moisture.
To help the hedge recover, prune out the dead branches to prevent disease spreading and encourage new growth. Deep-water the hedge thoroughly and consistently, making sure the entire root zone is covered, and apply a balanced fertiliser to support recovery. Mulch around the base to retain moisture and regulate soil temperature. Monitor for pests or fungal infections, and if you notice fungus or unusual decay, you may need a fungicide or professional advice. If the dieback continues despite care, it might be worth consulting a horticulturist to check for disease or soil issues.
Please let me know if you have any questions.
