Grapefruit mint blends beauty with good taste. Bright green leaves boast a taste that resembles spearmint with a twist of unsweetened grapefruit. Leaves release their flavor with simple bruising. Toss bruised leaves into ice water for a refreshing summer drink or add to iced tea.
This mint makes a pretty addition to a garden, although you may want to tuck plants into containers because of their spreading ways. Like most mints, grapefruit mint grows rampantly. Contain the spread by planting in confined spaces or containers.
Mints are notoriously easy to grow, and grapefruit mint is no exception. Plant in spring or fall up until 2 to 3 weeks before first frost in cold climates. Grapefruit mint tolerates light frost, but dies to the ground in winter in all but coastal climates. Fresh shoots appear in spring.
Plant Spacing: 12 to 18 inches. Plants Per Person: 1 to 2.
Secrets to Success »
Tuck plants into moist, fertile soil in part shade to full sun. Provide light shade during midday heat in hottest regions. Mints thrive in moist soil, but will grow in drier situations, although the patch may remain sparse. In early spring, fertilize plants with Bonnie Herb & Vegetable Plant Food. This organically based fertilizer is low in salt and won’t cause ugly brown leaf tips. Cut plants frequently to keep mint looking its best.
In coldest regions, mulch fall-planted mint after the ground freezes. If you grow mint in containers in areas with hard winters, place pots in an unheated garage or crawl space for winter. Or, pop plants out of pots and tuck into soil for overwintering. Repot in spring.
Harvest and Use »
Pick leaves frequently to ensure a steady supply of flavorful, tender new growth. The best time to harvest mint is midday, when essential oil concentrations are highest. Pick individual leaves or snip stems for a larger harvest.
Grapefruit mint flowers in late summer. As flowers form, flavor becomes bitter. Remove flower buds frequently to preserve flavor. If plants do bloom and you want to make a large harvest, cut plants back by up to two-thirds, removing all flowering stems. Harvest from new shoots that appear.
Use fresh mint leaves whole as a garnish, or chop to flavor salads, sauces, desserts, or vegetable dishes. To preserve mint, dry whole leaves and store in sealed containers in a dark place. To release flavor, break leaves just before using. You can also freeze mint, whole or chopped, in ice cube trays. Whole leaves frozen in ice cubes make everyday beverages feel like party fare.
