Caring for plants in the ground
Autumn-planted perennials need extra care and attention to keep them healthy and flowering for longer as the weather deteriorates.
Remove dead or damaged material when planting, so it can’t provide an entry point for pests and disease.
Avoid placing plants too close together. They need space for airflow and proper growth to keep them robust and reduce the risk of fungal problems such as mildew.
Deadhead regularly, but at the end of the season it can be worth leaving some seedheads in place as they look attractive when covered in winter frost and provide food for garden birds and over-wintering insects.
