The mint found in tubes of toothpaste, mouthwash products, gummies, medicines used to cure hiccups, ease indigestion, and soothe headaches is derived from the mint plant. The mint plant aka mint is a very nice plant to have indoors or outdoors. This is because it has a very pleasant fragrance. It is also because it looks great when its flowers bloom. 

In this article, I will share with you comprehensive information about how often to water mint.

How often should you water mint? This depends on multiple factors, including soil type, climate, size of the container, or if it’s planted directly in the ground.  On average, you will water mint once or twice a week.  However, always check the soil too if it’s wet, damp, or dry, in order to avoid over and under-watering.

How Often To Water Mint

Mint plants need various things to thrive. Perhaps the most important thing they need is water. Their roots must continually be in moist soil with good drainage for them to thrive. To ensure your mint plants have the water they need to thrive, you should water them every day in the morning. 

However, before you start doing so you should know that while mint plants like standing in moist soil, they do not like waterlogged soil. Therefore, before watering your mint plants, you should stick a finger into the soil just near where their stems meet the ground. If you feel that the soil is dry, you should water them. If you feel that the soil is sticky or wet, you should water them the next day. The purpose of doing this is to avoid waterlogging them. 

If you overwater your mint frequently, their waterlogged roots will start rotting and they will die. So water only after feeling the soil around their roots by sticking a finger into it. And only water them in the morning to allow the midday sun to evaporate excess water.

If you do not want to water your mint frequently, you should get self-watering containers. Self-watering containers will ensure the soil in them remains moist and never dries by drawing water from water reservoirs via osmosis. If you get self-watering containers, your only job will be to refill their water reservoirs every once in a while. No need to check soil moisture content and to water your mint every morning. And there is no risk of overwatering. 

How Often To Water Mint in Containers

Most people grow mint plants in pots/ containers. This is because they are very invasive. They can quickly take over a garden and affect other plants when they are grown in the ground. If you are growing mint plants in containers, you need to water them more frequently than if you are growing them in-ground. This is because container mint plants have only one source of water (you), while in-ground mint plants can also get water from nature.

Therefore, if you are growing mint plants in containers you need to water them frequently. Probably every single day. However, before you do, you should stick a finger into the soil in the containers to feel if it is moist. And you should only add water if it is not moist. 

How Often To Water Mint in Terracotta Clay Pots

Terracotta clay is a very porous material. Water leaches out of pots made of terracotta clay very fast. They kind of just hold the soil but not the water. So if you are growing mint in terracotta clay pots, you should water them more frequently than if you are growing them in any other type of container. But remember, before watering, you should assess the moisture content of the soil in the pots by sticking a finger in them.

How Often To Water Mint Set in the Full Sun

If you live in an area where the sun is hot and it comes out daily, you need to water your outdoor mint plants twice a day. This is especially true if you have set them in an area of your backyard or garden where they are exposed to the full sun. The reason why you need to water your mint plant twice a day is that the hot sun will cause your mint plants to lose plenty of water through evaporation. It will also dry out the soil in which they stand. 

So to ensure your mint plants do not get dehydrated, you should water them in the morning and in the late afternoon. But as always, before you do so you should assess the moisture content of the soil to ascertain if your plants really need water before watering them. Because overwatering is dangerous as I will show you below. 

Why You Should Not Overwater Your Mint Plants

Overwatering your mint plants is very harmful to them and can even kill them. This is because overwatering has three main negative effects. First, it washes away nutrients from near the roots of plants preventing plants from absorbing them and using them. Second, it drowns plant roots and prevents them from absorbing oxygen which they need to do to stay alive. Lastly, it makes plants more susceptible to diseases. In short, if you overwater your mint plants you make it difficult for them to survive.

The good news is that you will quickly know if you are overwatering your mint plants. You just need to watch out for signs of overwatering such as the yellowing of leaves and weak stems. Constantly overwatered mint plants also look droopy so this is something that you should also watch out for. 

In case your mint plants are constantly afflicted by diseases such as white mold stem rot, leaf blight, verticillium wilt, black stem rot, powdery mildew, and mint rust, you should also know that you are most likely overwatering them.

The solution to preventing yourself from overwatering your mint plants is to always ascertain if your plants really need water before watering them.

Why You Should Not Underwater Your Mint Plants

As you now know, overwatering is dangerous to mint plants. What you should also know is that underwatering is also dangerous to mint plants. This is because it leaves them dehydrated and it can lead to their deaths. 

You can also easily know if you are underwatering your plants. You just need to watch out for the signs of underwatering such as the yellowing of leaves and the wilting of the same leaves. The yellowing of leaves is both a sign of overwatering and underwatering. To know if the discoloration of leaves you are witnessing is because of overwatering or underwatering, you should check the conditions of the leaves. If they are droopy, the discoloration is a sign of overwatering. And if they are wilted, it is a sign of underwatering. 

When mint plants are underwatered, their roots tend to protrude through the surface. This is also a sign of underwatering that you should look out for.

The solution to underwatering your mint plants is to water them every morning after assessing the moisture level of the soil they stand-in.
