- Unprofessional watering and its solution
Unprofessional watering is a leading cause of turning your leaves brown. The mint is a well-growing plant and needs to be in proper maintenance, such as watering consistently. Many of us think that watering is a challenging task. However, it is not to be a challenging task but a puzzle between the overwatering and underwatering. Both the issues can affect the root tissues, unfortunately.
The mint plants are upgraded by the tissues and cells and hold water by their roots to source additional nutrients. In the professional’s view, you must water your plant by its sweet spot! Watering by the sweet spot means watering the mints adequately so that plants get to breathe correctly.

Also, the lack of water brings the stem into impoverished existence with brown leaves. We have a remedy for improper watering. See below.

Get a caretaker who will be consistent with watering in your absence. Don’t water twice a day if your mints are planted in a shady area. Besides, be mindful of watering your plants twice a day if you’ve grown them in the full sun. However, it would help if you created an environment depending on the humidity of your area. You’ve checked the soil if it is dry or wet. Then, create a schedule to water your mint by the climate.
- Heavy sunlight
Heat and a full sun provide the mint plants direct sunlight. However, mint plants are likely to grow in a shady area. Try to maintain between sun and shade and prefer to keep the plants mostly in the shade. You’ll get to see the growth quickly and thrive.
We recommend not keeping your plants directly in sunlight because we have told you earlier that mints are likely to grow in shady areas. Placing directly under the sunlight will eat your plants and turn them brown by their leaves. Plus, you won’t receive any benefits from your mint in the future. Heavy sunlight is responsible for burning your plant. Why not trying adapting the mints in a cold condition? Please do it!

The mint plants are much preferable to harvest in a shaded corner. Besides, try to maintain a corner of a brightly lit room. You must be careful to prevent too much sun. Also, don’t keep your plants under A/C source and artificial temperature regulating systems. Keeping your mint in a shady area will work moderately anyway.
- Constricted roots (Happens due to lack of space)
Constricted roots are another significant cause to turn your mint leaves brown. The plant starts growing its roots, and because of having improper space to grow the plant’s root, the plant doesn’t receive sufficient water from eating. You have to plant the mints in a larger area to outgrow the plant’s root in a planting pot. Once the roots run out of space, they feel restricted to grow in. The nature of mint roots may get constricted. The roots remain with all crossed patterns and can’t receive nutrients from the soil and start getting brown by leaves.
Remedies to constricted roots:
You must make a relatively early decision before it’s too late. Untangling the roots may be a good decision to revive any damage. As you know, the roots receive the necessary juice from the soil and make their life happen. They are considered to be part and parcel of the plant. After untangling the roots, you can switch the plant to fresh soil and prevent your plant from unfortunate issues. Why not giving your plant plenty of room to grow?
- Grayness and the ideal aging
Your mint leaves can turn brown due to natural aging. Comparing to all living things in the world, plants have a long lifespan. We have a mango tree in front of our home that was planted 150 years ago! However, we are not talking about those trees but mint trees. A mint plant lives between 5 to 10 years. After its biological age, the plant gets weaker and be in the natural aging. You may find your plants brown then. It is not happened due to improper watering and other diseases. Are your plants are old enough to get rotten? Mostly, when your mint plants have been going through natural aging, the mint plant starts turning brown by its leaves closest to the soil. Then, a time will come when the leaves will turn dark yellow and fall off the stem. No worry, this is a natural process.
Remedies to aging and brown leaves:
Although the mint leaves go through natural aging, they don’t fall off too quickly. Remember carefully pruning the plant by its edges. The process takes time but does the best work to keep your plant clean. Sometimes, you get rid of the aging issue through this if your plant is healthy. Unhealthy plants may go killed over time. Be mindful of not pruning with sick plants. It prevents the growth of the mint plants. Do them carefully.
- Nutrient deficiencies
Nutrient deficiencies turn the mint leaves brown. It happens when your plant can’t receive the required minerals from the soil. Indeed, the mint plants reserve enough nutrients in their roots. Ensure your soil is enriched with all necessary nutrients such as phosphorus, calcium, potassium, and nitrogen. Maintain watering to give the soil more ability to be healthy. Insufficiency of nutrition turns the mint leaves brown and will kill the plant thoroughly. Without planting in good soil, you can’t ensure your mint plant with proper minerals. Study more on soil preparation.
Remedies to nutrient deficiencies:
You can use an excellent fertilizer to rebuild nutrition deep inside the soil. Besides, it is a good idea to create compost yourself and apply it to the earth. Composting is an organic way to supply more nutrients to the soil. Making compost is much more comfortable with fruit and vegetable scraps. Do not over-fertilize your plant. It will get your mints with fertilizer burn and drive the leaves brown colored.
