Moneywort, or creeping Jenny, is either a dearly loved or vehemently hated member of the primrose family. This plant is considered by its fans to be a lovely, rapidly self-propagating ground-cover plant with a low-growth habit. Those who despise it believe it to be an aggressive fast-growing, quick-spreading invasive weed, difficult to eradicate. Because beauty really is in the eye of the beholder, moneywort enthusiasts enjoy the fact that these plants over winter easily and well with little, if any, assistance.
Mow creeping Jenny several times during the summer to keep it looking tidy.
Cut and collect moneywort in June if you plan to dry it. This is the best time of year for the activity, so it's wise to process as much dried herb as you think you'll need for the year. It can be gathered anytime during the growing season for use in fresh herbal applications.
Pull up excess plants when moneywort propagates and expands beyond the boundaries you have established for its location. Be nice to your neighbors and the great outdoors--don't let these plants spread beyond your own property line.
Reduce feeding and watering moneywort in the fall. Stop altogether during winter months, as the plants will benefit from a dormant period.
Mulch creeping Jenny with leaf mold or grass clippings just prior to the first expected frost date in regions with extremely brutal weather, if desired. It really isn't necessary because established plants return in spring unassisted.
