Aerogardens are a great way to grow your own herbs and veggies indoors, without the hassle of traditional gardening. But what do you do when your once lush and green mint leaves start turning yellow?

This can be a common problem that many Aerogarden users encounter, and it can be quite frustrating to see your herbs struggle. This issue can be caused by a variety of factors, ranging from plant diseases to environmental factors. And if left untreated, it can lead to a significant decrease in the quality of your harvest.

In this article, we’re going to dive into the common causes of yellowing mint leaves in your Aerogarden and offer solutions to bring your plants back to health.

Possible causes of yellowing mint leaves?

Aerogarden mint leaves turning yellow? This can be a common problem with indoor gardening, and there are various reasons why your mint leaves may be turning yellow. Here are a few:

  • One possible cause is lack of sunlight. Mint plants require several hours of sunlight each day, and if they are not receiving enough, the leaves can turn yellow.
  • Another possible cause is overwatering. While it is important to keep the roots moist, too much water can lead to root rot and yellowing leaves.
  • Also, nutrient deficiencies can also cause yellowing leaves. Mint plants require a balanced mix of nutrients, including nitrogen, phosphorus, and potassium, to thrive. If the aerogarden is not providing enough nutrients, the leaves may turn yellow.

It is important to consider all these possible causes when trying to determine why your aerogarden mint leaves are turning yellow, so you can take the appropriate steps to correct the problem and keep your mint plants healthy.

How to diagnose yellowing of aerogarden mint leaves

If you are an Aerogarden mint grower, you may have encountered the common issue of yellowing mint leaves. This can be frustrating, especially if you are looking forward to harvesting fresh mint for your culinary or medicinal needs. However, yellowing of Aerogarden mint leaves is a common problem that can be easily diagnosed and treated.

The first thing to check is the water level in the Aerogarden. Mint plants require a consistent supply of water, and if the water level is too low, it can cause stress to the plants, resulting in yellowing of the leaves.

Another factor to consider is the pH level of the water. Mint plants prefer a slightly acidic pH level of around 6.0-7.0. If the pH level is too high or too low, it can cause nutrient deficiencies, leading to yellowing of the leaves.

Finally, it is essential to check for signs of pest infestation as insects like spider mites and aphids can cause yellowing of the leaves.

By addressing these common issues, you can diagnose and treat yellowing of Aerogarden mint leaves and ensure a healthy and thriving mint plant.

Tips for preventing aerogarden mint leaves turning yellow 

Fortunately, there are some steps you can take to prevent your Aerogarden mint leaves from turning yellow.

1. Sufficient light:

Make sure you are providing enough light. Mint plants require at least 12 hours of light per day, so if your Aerogarden is not getting enough light, the leaves may start to yellow. Consider moving your Aerogarden to a sunnier location or adding a grow light to provide sufficient light for your plants.

2. Water level:

Ensure that you are not overwatering your mint plants. While Aerogardens are designed to provide water and nutrients automatically, it is still possible to overwater your plants. Check the water level regularly and only refill it when it is low. Avoid adding too much water at once, as this can lead to waterlogged roots and yellowed leaves.

3. Nutrient balance:

Consider adding some nutrients to your Aerogarden water. Mint plants, like all plants, require a balance of nutrients to thrive. Aerogarden makes specially-formulated nutrient solutions for their systems.

Troubleshooting tips for growing healthier aerogarden mint leaves

If you’re experiencing issues with your Aerogarden mint leaves turning yellow, don’t worry, it’s a common problem that can be fixed with some troubleshooting.

Here are a few tips:

  1. The first step is to check the water level of your Aerogarden. If it’s too low, this could be causing stress to the plants and resulting in yellowing leaves. Similarly, if the water is too high, it could be drowning the roots and causing the same issue.
  2. Another factor to consider is the pH level of the water. Mint plants prefer a pH level of 6.0-7.0, so check the pH level and adjust accordingly.
  3. Also, if the plants are getting too much or too little light, this can also cause yellowing leaves. Ensure that the light is adjusted to the recommended height and duration for mint plants.
  4. Finally, if all else fails, you may need to prune the plant to remove any damaged leaves and encourage new growth.

By following these troubleshooting tips, you’ll be back to growing healthy Aerogarden mint leaves in no time.
