I’ll be the first to admit that I have an overwatered plant or two in my garden every year. It’s not so bad now, but my indoor plants used to try their best to run away when they saw me coming with the watering can. Spoiler alert: They didn’t get very far.

In my defense, I was not very informed as to how much water plants need. I just assumed you had to water indoor plants once or twice each week, and every day for outdoor vegetables. Wouldn’t you know, there’s a little more to it than that, like how close to a heat source your indoor plants are, or how windy it is for your outdoor plants. Lucky for me (and my vegetables) there are a few ways to tell if you have an overwatered plant.

The 7 telltale signs of an overwatered plant

1. Wilted leaves. Whether you have an underwatered or overwatered plant, you’ll likely see leaves that look sad. The difference between the two is that an overwatered plant will have yellowed, soggy-feeling leaves.

2. Brown leaves. Like wilted leaves, brown leaves can be a sign of either too much or too little water. How can you tell the difference? Dig down into the soil a bit with your finger and see what it feels like. Even soil that’s dry at the surface could be quite wet once you get down an inch or so.

3. Shedding leaves. All plants drop leaves, but if you’re finding both new and old leaves dropping from your plants, there’s a darn good chance you’ve overwatered.

4. Mushy stems. How does the base of your plant feel? Is it weak and soggy? You guessed it: too much water.

5. Moldy soil. If you’re finding the surface soil around your plant is moldy or growing fungus, that’s a definite sign of an overwatered plant. Remove the affected soil and make sure it has a chance to dry.

6. Blistered leaves. When plants get too much water too quickly, their leaves fill with fluid and the cells burst.

7. Root rot. This identifier may be a little harder to notice, but it can be fatal to plants. Your best bet here is to dig up the plant and try to clean out the roots by shearing off any dead and rotten sections. You may also need to trim back any foliage. Run the roots under clean water and repot the plant in a clean pot with fresh soil, or plant it in a new area in the ground, ensuring the soil is free of mold and mildew first.

How to cure an overwatered plant

Aside from root rot, the easiest and most effective way to fix an overwatering problem is to just change your evil ways and stop watering your plants. In most circumstances, that will be enough to get your plant back to full strength and living a happy plant life.

For more severe cases, move your plant to a shady spot (assuming it’s in a container). We don’t want the water to evaporate too quickly. One extreme to another is not a great situation for plants. If it’s really in rough shape, take the same steps that you would for root rot.

Lastly, change how you water your plants. Check the soil every couple of days by pushing your finger in an inch or two. If the soil is wet, your plant does not need water.

That’s really it. The secret to keeping your plants happy and healthy is to try to catch these issues as soon as you can. Just like with humans, the sooner you can catch a problem, the sooner and more successfully you can correct it.
