One of the most common problems with pepper plants is wilting leaves. Most of the time, a little bit of water will do the trick and help them come back to a healthy state. However, if you’re looking for more methods to save your pepper plant, I have a few go-to tricks.
Here are six tips for reviving your wilting pepper plants:
- Check the soil’s moisture.
- Provide shade to your plant.
- Manage the soil’s pH.
- Bring pepper plants indoors during the cold.
- Observe and maintain your plant care routine.
- Check and, if possible, treat the plant’s diseases.
In this article, I will go over a few common causes of wilting pepper plants. And as you read on, you will learn how to utilize these tips to revive wilting peppers in your garden.
1. Check the Soil’s Moisture
New gardeners might instantly think of watering their pepper plants when they see them wilting. While underwatering is the most common cause of wilting among pepper plants, it is not always the case.
In some cases, your pepper plants may be wilting because of overwatering. That is why it could do more harm than good when you water your plant the instant you see it wilting.
It’s essential to check the soil moisture before deciding your plant needs more water or less of it. It is worth noting that giving your plants the proper amount of moisture isn’t as simple as pouring in the “right” amount every day.
Sometimes, the soil becomes hydrophobic and doesn’t absorb water as it should. Too much shade makes for plants that don’t dry off well, leaving your plants moldy. Additionally, getting the correct water temperature is as important as the amount of water. Being sure your plants are drying in between cycles keeps your soil healthy.
You should consider watering your pepper plant thoroughly once a week and allowing the water to drain through the soil or pot entirely.
On the hottest of summer days, you may consider using a moisture meter or feeling with your fingers to see if an extra watering session is necessary. You always need to check first because even if we feel hot, our plants may still be working through the water.
Adding a splash of water to your pepper plant and making sure the roots are getting moist usually brings plants back to life. Put the hose on your plant, take a step back, and wait for your plant to unwilt. It can take several hours, so be patient.
If you think your watering technique can use a little work, I suggest purchasing a moisture meter for your garden. Moisture meters work wonders and can tell you about more than just moisture, such as pH.
2. Provide Shade to Your Plant
Peppers are delicious and have a little bit of a spicy kick. Some variants can be very spicy, making them more appealing to some people who want extra spiciness.
Because of this, many of us assume that peppers can take extra high heat. However, this isn’t the case. Like the rest of your veggies, peppers need some shade and relief every once in a while. This is especially true if you live in an area with a hot, humid climate.
We know how vital planting temperature is. We triple-check what zone our garden is in, why we plant in the spring instead of the winter, and why we (unfortunately) can’t grow plants like coconut trees anywhere we’d like.
Pepper plants like a temperature higher than 60 °F (15.5 °C) but nothing above 95 °F (32.2 °C) for too long. Keep in mind that some regions of your garden may gather heat differently.
Suppose you have a garden underneath or near a reflective surface, like a tin roof or your car. In that case, the heat may be different than across the garden near a water feature.
You can check the temperature of your soil with a moisture meter or thermometer. Otherwise, you can look at the temperature on your weather app to see if your plants are being exposed to heat that may be too much for them.
You can fix your wilting pepper plant by moving it into the shade or adding some shade if it’s sown into the ground. There are plant shades you can buy online or some that you can quickly build yourself.

3. Manage the Soil’s pH
Soil pH is another one of those things you should look into if you’re worried about the health of your garden. If you’ve noticed that all of your plants, not just your pepper plants, seem to be wilting or not growing to their full potential, you may have a pH problem.
You will know the acidity or alkalinity of your garden by checking the soil pH. Despite the many nutrients in your soil, your plants can’t access them unless the pH is correct. Only certain nutrients are available at certain pH levels.
The scale goes from 0-12, with 7 being a true neutral and most plants liking something around 6.8, just barely acidic. Only a few plants like blueberries prefer an acidic soil environment.
Pepper plants, like most plants, want a soil just slightly acidic between 6.5-7.0 on the pH scale. At this level, the plant can get plenty of phosphorus and potassium as long as they are available in your soil.
To test your plant soil’s pH, you can buy an online testing kit or send a sample into a lab.
You can often fix highly acidic soil with liming. Unfortunately, there are no quick fixes for adjusting your soil pH. However, mulching and composting usually help balance soil pH.
This video shows how to utilize the liming technique for more alkaline soil:
Whatever fix you use, practice patience and only do the recommended amount. Doubling the lime in your soil won’t adjust the soil any faster, but it will give you further issues with your soil pH.
It also helps to remember that liming is not an instant fix if you need to increase the soil pH. The process takes time and trying to speed up the process may be counterproductive. On the other hand, lowering the soil pH also takes time.
4. Bring Pepper Plants Indoors During the Cold
Like hot weather can wilt your pepper plants, so can cold weather.
As mentioned above, pepper plants thrive in places where the temperature is above sixty degrees (even at night!). If you’re experiencing chillier temperatures than usual, bring your pepper plants in from the cold and put them back out when it’s warmer.
Pepper plants, especially younger ones, may suffer from stress when there are sudden changes in temperatures. They can manifest this through the wilting of their leaves.
Check the weather forecast regularly and keep your plant indoors for as long as possible until the outside temperature becomes steadily warmer. You can move your plants back outdoors when the threat of the last frost passes.
However, this method only works with potted pepper plants. Those planted into your garden soil may benefit from plastic mulching. You can spread a layer of black plastic on the ground and cut big enough holes for your plants to grow out.
5. Observe and Maintain Your Plant Care Routine
Many of us begin our pepper plants inside. As it gets sunnier and they start to grow, we move them outdoors to their “natural” habitat and think mother nature will just take it from there. However, you raised your pepper plants from seeds to sprouts, and they remember all of the love and care you gave them.
Did you give your pepper plants room temperature water, and now they’re getting cold water from the hose? Did you give them lots of shade, and now they’re exposed to the direct sun?
If you don’t keep your house over eighty degrees, and once it starts to get hot outdoors, your peppers will be shocked by the heat. The bottom line is your plants have to adjust to the outside just like we do.
Plants can feel stressed from the sudden change in the environment. There are a few strategies you can attempt if their leaves have begun wilting due to stress. Figure out what in your routine changed, and then go from there.
For example, you can leave them in the pots for a bit longer instead of sowing them straight into the ground to move them out of the sun and back into the shade whenever necessary.
If watering seems to be the element that changed, invest in a watering can and feed your peppers with tap water instead of water from the hose.
6. Check and, if Possible, Treat the Plant’s Diseases
Hopefully, one of the strategies above helped your pepper plants to regain their vitality and produce fruit. However, you may be wondering why your pepper plants began wilting in the first place.
Above, we talked about solving the most common wilting problems. You can add compost, mulch, or fertilizer for soil issues like pH or nutrient deficiencies. The watering issue can be solved with a moisture check and watering adjustment. However, there’s also a possibility that a wilting pepper plant has experienced an infestation or root rot.
It is difficult to revive a pepper plant (or any plant) after a bug infestation or things like mold and root rot. Wilting leaves or pepper plants are a definite sign, but usually, these things come with more symptoms than just that. Some common ailments for pepper plants that make leaves wilt are:
- Root rot
- Bug infestation
- Southern blight
Below, I will share some more about common pepper plant diseases, how to look for them, and what can be done to salvage your plant or the rest of your garden.
Root Rot
Root rot can be caused by watering your pepper plants too much and not letting the soil drain completely. When soil gathers at the bottoms of plants near the roots, a moldy rot can begin forming.
You’ll notice rapidly wilting pepper plants that soon die, even after watering. You can pull up this dead plant and see the root rot.
Once wilting occurs due to root rot, it will be impossible to save the plant. However, after confirming that it is the cause of wilting, you can check the other nearby plants and, hopefully, remedy the situation before they start dying.
Your watering techniques have everything to do with root rot, though sometimes you may have just gotten the unlucky pick at the plant nursery. Invest in an irrigation system or moisture meter to give you more insight into how your pepper plants take up water.
If you are using a pot for your pepper plants, clean it out thoroughly with some bleach and water before beginning again and disposing of all infected soil. It is best to use sterile materials to prevent the spread of diseases and suffering from the same issues again.
Bug Infestation
Many things can cause bug infestations. You may have grabbed a plant that already had an infestation, a nearby plant may have passed some bugs on, or a swarm of insects may have found your garden and decided to make it a home.
Other than the wilting, you may notice tiny holes in your plant leaves or the most obvious symptom–bugs flying around. Pepper weevils and pepper hornworms are typical suspects and the usual garden pests.
To get rid of bugs in your plant, you can use a natural remedy like neem oil or soap and water. Additionally, make sure your garden has many little helper bugs, like ladybugs. These little helpers will eat or get rid of the things that aren’t supposed to be there.
Southern Blight
If you live in the south, southern blight may be causing your wilted pepper plants. Southern blight typically happens in hot, humid climates. It can kill anything from a tomato to a carrot if gone unnoticed. It’s caused by a fungus called Athelia rolfsii. Pepper leaves will wilt, and you’ll notice brown roots near the bottom of the plant.
If you find that southern blight has caused the wilting of your plants, you’ll need to pack up and garden elsewhere while you treat the soil with the disease.
Plants suffering from this condition are beyond saving, and you’ll need to consider growing your plants in pots. If so, be sure to get your potting soil from a reliable source to avoid other possible diseases from infecting your new pepper plants.
Final Thoughts
Pepper plant leaves commonly wilt when they need more water. If you’ve noticed your pepper plant has become droopy, check the soil moisture and adjust watering accordingly. Additionally, you can check your pepper plant’s lighting, soil pH, and temperature.
Sometimes, a wilting pepper plant can signify something more nefarious, like root rot or an infestation of pests. Unfortunately, you can’t revive your pepper plant after an infestation. Still, you can thoroughly wash your pot or further protect your remaining pepper plants from infestation with natural supplements like neem oil.
