Mint is a fast grass that one does not easily kill. Because it also spreads very quickly, most safely grow it in pots, so that it does not take over the garden and does not choke other plants. In one growing season mint can reach one to two feet of height.
If the conditions are ideal, with a lot of sunshine, water and rich soil, it even can spread some inches weekly during the most active period.
How to Water and Care for Mint
About watering mint widely needs around one to two inches of water weekly, about all four days. The soil must stay always wet, but never fully soaked or blocked. Most important is keep the soil equally wet.
Good rule is dampen when the upper inch of the soil feels dry; that usually means each some days in warm weather and less often when it is more cool.
In the warmer months, dampen one or twice weekly commonly is enough. Even so, if it is especially warm or the plant stands in full sun, more common watering is needed. Even everyday watering can be required, and in really hot periods sometimes twice a day.
Garden plants require water each one or two days, so that the soil stay equally wet. Freshly sprouted plants require everyday watering at warm temperatures.
Pots dry more quickly then garden beds. Mint in a smaller pot, for instance eight-inch tin, will have to be dampened very often. For instance, if peppermint or sweet mint grows in a five-inch pot without direct sunshine, around half cup of water all nine days can work.
Always ensure that the pot has drain holes, so that extra water can spill. Clay pots should be avoided, because they too quickly dry out the soil. Non-porous tin keeps the moisture more well.
Mature garden plants can last short dry periods, but they best grow, when one dampens deeply and later leaves the soil slightly dry before the next watering. Climate, solar exposure and the size of the pot all affect, how often the plant needs attention. Also seasonal changes matter (more water in summer and less in winter).
Too much watering damages the roots and leads to yellowing leaves.
Wilting leaves and dry soil are signs, that the plant needs water right away. Mint also can grow in water by means of hydroponics. The tin or glass should stay full almost always, although not always to the whole edge.
Roots need oxygen, and in water they receive it from the oxygen-rich water itself. Often changingthe water helps to keep the oxygen level fresh. In dense, too packed soil water does not move well and lacks space for air, what can kill the roots after a bit of time.
Mint favours soil with a fairly neutral pH, around 6.5 to 7. Fertilizing does not always need to happen, because mint quickly grows itself, but a thin layer of organic fertilizer or dressing all some weeks can help.
