Identify my pennyroyal
Mints are a genus (Mentha) of herbaceous perennial plants in the Lamiaceae family, in the Nepetoideae subfamily, which includes a number of species in which many are cultivated like herbs, spices, ornamental, and medicinal plants.
It's easy to recognize them: rub a leaf to release its smell. When in doubt, look for opposing leafs and very pronounced veins.
Sow my pennyroyal
Seeding mint is very easy. In open soil, sow as soon as May, in any ordinary soil, by spreading the seeds regularly.
Inside, sow in a box, in a suitable potting soil. Cover the seeds very slightly, and tamp well. Keep the soil slightly moist until germination.
Dibble my pennyroyal
If you have sown in a box, you can transplant your mint as soon as it has some true leaves, when strong frosts are no longer a threat.
Gently separate the plants, and plant them every 5 cm at their final location.
Mint likes to grow in semi shade: the full sun slows its growth, and will force you to unnecessarily water more! It supports frost and will easily grow back to the same location year after year.
In open soil, a cool soil moderatly rich will do, in full sun or semi shade.
The soil must be well drained to avoid stagnant water: in pots the ideal is a substrate made of potting soil, with an addition of 10% sand, but mint is not very difficult!
Indoors, behind a window, or on a balcony, in a pot or in a planter: if you want to keep it in a pot, replant it immediately after the purchase in a larger pot - a simple terracotta pot will do the trick !
Plant my pennyroyal
The mint loves to grow in partial shade: direct sunlight slows its growth, and will uselessly ask you for more water. It holds up against frost and will easily regrew in the same spot year after year.
The soil must be well drained in order to prevent water from stagnating: the ideal is a substrate of potting soil with an addition of 10% sand, but mint isn't very difficult!
It is also perfectly suited for indoors, behind a window, or on a balcony, potted or in a box: if you wish to keep it potted, replant it immediately in a bigger pot after buying — a simple pot in terra cotta will do the trick!
Plant it starting in April to benefit from its leaves as soon a nice days arrive.
Pinch my pennyroyal
A few weeks after planting, pinch the young shoots in order to encourage new offshoots: sever the end of the stem between your thumb and index finger. Like so, lateral stems will grow.
You can repeat the operation several times at the tip of each stem.
Water my pennyroyal
The mint rather prefers dry soils: water mainly just before planting, during very hot periods, and of course if you are cultivating the mint in a pot.
Golden rule: never water during direct sunlight: this can burn the foliage, and this wastes water. Water in the evening, but not too late.
Mulch my pennyroyal
You can mulch between the plants one to two weeks after planting with the aid of a mulch which holds in moisture. This will limit evaporation from the soil, and thus the need to water and to weed.
Reap my pennyroyal
You can pick the mint leaves all throughout spring and summer according to your needs. Preferably choose the biggest leaves by cutting the entire stem to encourage new shoots to sprout.
It's better to pick in the morning before the sun comes to spoil the aromatic quality of the leaves.
Also take the time to remove all the buds whose growth is tiring out your mint to the detriment of the leaves!
Propagate my pennyroyal
Dividing the plant is normally undertaken in spring or in autumn.
Start by digging up the plant with its roots, separate the plants gently, and transplant each section in a mix of garden soil and garden soil, potentially adding a little bit of compost. Water generously for two to three weeks.
Repot my pennyroyal
Repot every year potted plants by adding a little compost: the mint doesn't ask for much, but growing it in a pot will eventually make it a bit pale, and repotting it will rejuvenate it.
