Herbs can be cut back to encourage new growth for harvesting before the first frosts. Leave a section of each herb for immediate cutting. Seeds of herbs such as Fennel and Dill can be collected for resowing.
It is a good idea to thin leaves and pinch out any top growth on tomato plants so energy will go into the fruit production. Removing leaves will help air to circulate and prevent disease. Feed with high potash tomato fertiliser and make sure to water regularly.
Along roadside verges look out for Knapweed and Wild marjoram that can also be found in meadows along with Hemp agrimony that is loved by insects and butterflies and the flowers and seedheads of Yellow rattle.
