The peppermint herb is grown extensively as commercial ventures in many parts of the world including in large areas of Europe, in Asia, and in the North American continent.

For ideal growth of the peppermint the recommended pH range is from 6.0 to 7.5. The varieties of mints, including the peppermint and the spearmint, seem to thrive best and grow well full sunlight, but some of these plants also quite well even in partially shaded areas. Considerable shade is tolerated by some of the mints at the same time, like the water mint, which can tolerate considerable shades for long periods of time. At the same time, plants like the Corsican mint require shade for optimum growth at any time. Full sunlight exposure year round is necessary for mints to develop their best flavor and fragrance in the northern climes. The peppermint must always be kept well watered for optimum growth. The mints in general can be grown from stocked seed; this is not always advisable as a cultivation strategy, as the majority of mints do not grow well from seed. The best way to propagate the different cultivated mints is by using stem cuttings which are taken from well established plants just before these plants bloom, or the cutting can be taken by dividing existing plants into many parts, this must be done for optimal results during the early spring, or the cutting can be bought from nurseries. The planted peppermint plants must be space at least 45 cm or 18 inches apart ideally. The mints spread and grow well once the roots are established, rapid growth is also possible because of underground runners or stolons present in the plant. The herb garden in which the mints are grown must be prevented from being overtaken by the fast growing mints. Prevent the mints from expanding their area of growth by digging up unwanted runners every spring, or you can even curb the spread of the underground runners by sinking some drainage tiles or plastic dividers into the soil around near the areas in which the plants are growing, up to a minimum depth of about 30 cm or 12 inches. The mints can also be planted in large containers or pots equipped with drainage holes, and these can then be sunk into the ground. A bushy growth in the plant can also be induced by pinching off the flowers from time to time. The planted mints must be renewed once every three years by carefully dividing and replanting the roots, during the next spring or fall season. New spots are ideal for the growth of the peppermint, as this mint in particular, does not grow very well in the same location for more than a few years at a time. Mints are also very susceptible to infestations from common plant aphids, from cutworms and spider mites, and especially from the mint flea beetles, as well as the verticillium wilt disease and from fungal rust-particularly if the soil is too rich in nutrients. The immediate step to take incase of diseased plants is to dig them up and burned them at once. New mint plants can be re-planted in the next season in a different location. The plants must be protected in areas where winters are usually harsh and cold, the plants can be covered with straw - not soil -so as to prevent damage to the runners from the cold and frost. During the early weeks of the fall season or in the spring, establish indoor plants using commercial potting soils. The containers or the pots which are utilized must be large enough so as to give the creeping roots sufficient room for their optimal development. Plants which are grown indoors require at least 5 hours of strong sunlight daily for optimal growth. The soil in which the plants are growing must be kept moist at all times but never soggy. When the plants have grown well, it is important to apply a liquid houseplant fertilizer used at half strength for every 3 or 4 weeks of growth. Flowering can be prevented and tastier leaves can be ensured, by carefully keeping the stems cut back to 13 cm or 5 inches. Re-pot the plants when or if they start to turn yellow, this time the pot must be a larger container, or you can even divide the root mass into separate pots each propagate the herb in this way.
