Peppermint (Mentha x piperita) is a hybrid cross between watermint and spearmint, so it cannot be grown from seed. Once established in your garden you will never be without this welcome refreshing culinary and oh so helpful medicinal herb. Grows 1 - 3 feet high and spreads laterally. Keep it pinched to encourage bushy growth. Be sure to provide a spot with good sunshine and drainage. Hardy to Zone 4(b) with winter protection. One 4" pot will ship at a time favorable to its growth in your zone in Spring.
INSTRUCTIONS ON RECEIPT: Open immediately and give a drink of water, preferably filtered water. If using tap water, allow the water to “breathe” overnight before using to dissipate any chlorine which can be fatal to delicate organic seedlings. Put under grow light or near a natural light source, preferably without cold or drafts for at least a few days to settle down from its journey, keeping it moist but not waterlogged. If weather is not permissible you can hold your seedling for some time, potting up as necessary after a month. (Keep in its original pot for that long if you are not moving to the garden, as a new growing medium or too large a pot could cause failure.) If weather is permissible, begin your hardening off process of very gradual exposure to outside elements – 15 minutes at a time, graduating up to a full day by 15 minute to half hour increments. Watch carefully! If it is warm already in your growing zone, you can quickly lose transplants by rushing this process. Patience is rewarded with a vigorous transplant. When fully hardened off, situate to their permanent garden spot and let rest a day or two there, again, watching carefully for any sign of distress. Then, when you have a nice cloudy day in the offing, transplant into the garden, providing any support or cover required, giving a shot of organic fertilizer (I recommend Espoma). Keep watered, but not waterlogged. Keep a watchful eye on your baby.
