If its Oreganum onites (french or pot marjoram) it will be more tender than other oreganos/marjoram and may need winter protection from frosts

It's probably quite woody by now, Andy, so I would cut it back to about an inch or two above soil level, and pot it into some fresh compost. You can keep it indoors on a sunny windowsill to encourage new growth through the winter months, or put the pot outdoors in a sheltered, sunny position and it'll put up fresh, soft growth next spring.
