Mints are hardy perennials grown from divisions of established plants. Mints can be divided--established plants sliced in half by a spade roots and all--anytime during the growing season. They are best started in the cool weather of spring or fall.
Description. Mints are hardy, upright perennials that generally grow from 2 to 3 feet tall, though a few grow much shorter. Mints have smooth, four-sided stems with dark green, creased, round to oval leaves pointed at the tip. Mints flower in mid to late summer producing whorls of small white to lavender blossoms on terminal spikes. There are many varieties of mint. Peppermint (Mentha piperita) and spearmint (M. spicata) are the best known.
Yield. Plant one or two mints per household. A variety of mints can be grown in separate containers.
Site. Plant mints in full sun; they will tolerate partial shade. Mints grow best in moist but well-drained soil rich in organic matter. They prefer a soil pH of 6.0 to 7.0. Mints spread rapidly by shallow, underground runners; contain mints within metal strips or bottomless containers 10-inches deep sunk into the ground.
