How Often Do You Water Mint? (Tips & Tricks To Prevent Overwatering)

Mint is well known for its aromatic characteristics, especially in gums and balms. Coming from the Lamiaceae family, it has square stems, quite simplified leaves, and tubular flowers.

Mint goes along really well with other different recipes and delicious dishes, it gives that sweet and cooling sensation

Watering is a baby step in growing mint, and the best is to create a diary to monitor better the soil’s moist and prevent the common excessive watering issue. Remember, consistency is the key.

Weather conditions and the soil will determine how much and how often the mint needs watering.

Fun Fact: Ancient Romans and Greeks used the mint flavor as a shower gel and perfume/cologne. Plus, if the house smelled mint, it is considered as the most warm welcoming way for guests.

How Often Do You Water Mint?


Mint should be watered twice a week and requires even watering but not full moisture, we don’t want any root rotting issues, do we?

Regarding the temperature change and other factors like rainfall, and sunlight, the surface of the mint needs to feel a bit dry. If in doubt whether it needs water or not, put it off for tomorrow. 

In the table down below, I will explain clearly the watering conditions and the frequency of watering related to these conditions.


The Frequency of Watering

Mint Plant Indoor Watering Twice a week will be ideal for the average temperature (55°F-70°F). Increase watering during hot days and decrease on cold and cold days. Soil moisture determines the water need.
Mint Plant Outdoor Watering Soak the soil twice a week and spread the water evenly to make sure that reaches the root. Depending on sun exposure, you can increase it to 3 times a week (if necessary).
Mint Plant Pot Watering Pick good drainage with holes and don’t let the root stay in the water for too long. Apply the same 2-3 times per week watering rule.
Mint Plant Seed Watering Seeds require everyday watering and over time every 2 days will be ideal as they start to establish.

When watering the mint plant in pots, keep in mind to soak it thoroughly and don’t let the water sit in the root.

Do not shock the mint plant with cold water, it would be highly appreciated using lukewarm water.

The best time for watering mint is early in the morning or afternoon. For indoor growing, place the pot somewhere where the sun shines and make sure that it gets 5 hours of sun every day for optimal growth. Mint can tolerate shade, but the leaves won’t grow as vibrant as they should, rather the color will be pale.

How Much Should You Water Mint?

Depending on the surrounded circumstances (location, temperature, sunlight, and season) the amount of watering should go this way:

Weather Conditions

The Amount of Watering

Watering Mint in Peak Heat (Spring/Summer) During Spring and Summer times, you need to water 3 times a week as you know the heat makes water evaporate quicker. Make sure 1-1.5 inch deep and even watering is required.
Watering Mint in Cool Temperatures (Fall/Winter) Mint can survive cold winter temperatures unless it’s not covered in snow. Trimming and covering will prevent frost. Check weekly, and water once every 2 weeks in deep soak.
Watering Mint After Heavy Rain Week If it had rained at least 3 days a week, avoid watering, mother nature has moisturized the soil.

Sings of Overwatering Mint Plant & How to Fix


The color switch in the leaves is the first sign of overwatering or underwatering problems. After a short time, the yellow color will turn brown and fall off eventually. The only thing you can do is to cut the dead leaves, plant new seeds, and transplant them to another larger pot or container with new soil.

The following excessive watering signal is when the soil stays mushy and wet a couple of days after watering. Poke your finger at least an inch deep to figure out the dryness. Make sure it’s completely dry before you decide to water it.

The next overwatering sign is when you haven’t noticed any visible growth. This happens in most cases because of the root rotting (not well-drainage). The water gathers in the bottom and the root can’t breathe as it is supposed to. Try to change the soil, remove the plate and relocate the pot.

The case can switch up entirely when you water applying the correct amount and frequency and still encounter overwatering. Maybe you aren’t giving the mint plant enough direct sun every day. It should 5-6 hours, so the water photosynthesis can happen. 

If molding happens across the plant, then overwatering is in question because insects and fungus bacteria love to gather. Remove the plant and use an anti-fungal solution. Place the mint plant outdoors in the sun to dry the soil.

How to Grow Lots of Mint in a Container/Pot 

  • Do not overfeed the mint plant and don’t fertilize either, this will affect in flavor.
  • Find the location where the mint plant will be exposed to direct sunlight for at least 5-6 hours each and every day.
  •  Increase and decrease the watering as the temperatures changes during the seasons. 
  • Neither leaves the soil wet nor dry, find the balance by keeping a watering schedule.

A Brief Recap

Hopefully, the article was helpful enough because I tried to include all the possible watering scenarios. As I mentioned in the article above, water twice a week regularly and check the soil every 3-4 days because other factors play a significant role in the watering frequency.

That was pretty much for today, meet me in the next article.
