When plants, especially plants in containers, are having problems, the first environmental condition to evaluate is soil moisture. Start with this article on watering plants in containers: https://www.gardeningknowhow.com/special/containers/container-plant-watering.htm
If nothing here seems applicable, you might be having trouble with insects or disease. You can contact the Master Gardeners to analyze samples and recommend treatment : http://mastergardeners.org.uk/get-involved/find-your-nearest-master-gardener/
