How can I stop my Thyme becoming leggy?

Firstly, create a strong, healthy plant by growing your Thyme in the sunniest place possible in a very free-draining soil. Thymes will survive winter wind and cold if their roots do not sit in a heavy, waterlogged position. If growing in a container, choose a pot with drainage holes in the bottom and fill with a gritty, soil based compost. Avoid using a general purpose peat compost as this will cause your Thyme to develop soft, weak growth lacking in scent and flavour. Plants grown inside will also suffer with this problem so try to give your plants as much fresh air as possible. Then all you have to remember is to trim off all of the flowers as they fade. This is especially important for prostrate, carpeting Thymes, which always flower so profusely. Leaving on a thick covering of decaying flowers will suffocate and rot any fresh, new growth below. Removing dead flowers will encourage dense re-growth which will reduce the likelihood of leggy plants and winter fatalities.
