Herb gardens often become overrun by zealous growers that need to be kept in check.
Near the end of the season, and while the ground is still warm, the most vigorous herbaceous plants can be trimmed back, lifted and divided to rejuvenate them and control their spread. This method can be used on marjoram (oregano), chives, creeping thyme and lemon balm.
Newly planted divisions will sulk for a couple of weeks, then perk up, root out and put on some growth before going dormant for winter.
