Mature Thyme

My thyme has gone very woody and always seems in flower what is best, should I be cutting it right back to nearly nothing

 

I have recently trimmed my thymes back by half to encourage fresh growth but they were quite young plants. If yours are more than a couple of years old and very woody they may not respond well to hard pruning but it might be worth taking a risk and using any fresh growth to make softwood cuttings in spring. Be sure that the plants are in free draining, nutrient poor soil and in full sun.
