How to Cure Bacterial Leaf Spots on Peppers

You may be wondering how to cure bacterial leaf spots on peppers after seeing small spots on the leaves. Unfortunately, there’s no cure for leaf spots once symptoms manifest, but there are certain actions you can take to prevent it from infecting your plants in the first place.

Before you can prevent this disease, you need to know what it is. Bacterial leaf spot is a foliar disease that can permanently damage your pepper plants. It’s one of the most common pepper plant diseases in the United States.

How to Cure Bacterial Leaf Spots on Peppers

What are the Symptoms of Bacterial Leaf Spots?

Once you notice small water-soaked spots under your pepper leaves, this may be a sign of a bacterial leaf spot. These spots can easily grow larger, and the leaves will turn brown and become slightly raised. You’ll also notice that some of the spots in the upper side of the leaves with beige centers and dark brown edges.

When the spotted leaves start to yellow, they’ll start to drop to the ground. The loss of leaves may expose your peppers under direct sunlight, causing sunscald. Additionally, without enough leaves, your pepper plants won’t be able to properly grow and develop flavorful fruit.

Bacterial leaf spot can also spread to your peppers. The remaining fruits may not be harvestable because infected peppers are smaller and sometimes have deformities. The bacterial infection is not the main cause of pepper decay, but the lesions on the fruit make them susceptible to other pathogens that can cause decay and other diseases.


How to Prevent Bacterial Leaf Spots

Remember that bacterial leaf spot has no cure. This means that if the symptoms start spreading, it’ll be too late to stop them. As mentioned, there are several things you can do to prevent bacterial leaf spots from developing.

One way to prevent the spread of bacterial leaf spot is through crop rotation. Make sure not to plant peppers in the same location within the past four to five years.

After an entire growing season, throw away any crop debris from your garden beds. Don’t turn them into the compost because this debris may contain infectious diseases that may harm your new plants once you’ve cleared out everything, till the soil to get rid of remaining bacteria.

Bacterial leaf spot is typically caused by damp soil getting onto the leaves, usually through watering overhead. Prevent excessive splattering by watering your pepper plants using a soaker hose or an appropriate irrigation system. Also, as much as possible, don’t water overhead.

The disease can also spread through contaminated seeds. To ensure that your seeds and seedlings are disease-free, buy them from a trusted local garden shop. Don’t use your pepper seeds if you’ve had problems with bacterial leaf spot before.


Other Ways to Prevent Bacterial Lead Spots

There are other ways you can do to prevent bacterial leaf spot. These include planting resistant pepper variants; using mulch plants with organic materials; switching to drip irrigation; eliminating extra moisture; regularly checking your pepper plants for weeds and soaking your seeds in a chlorine solution for two minutes.

In case you’re wondering, if you don’t know how to make a chlorine solution, try mixing 1-part bleach and nine parts water. Furthermore, you need to make sure that your seeds are rinsed off and dried well before you sow them.


Why It Pays to Grow Your Peppers in a Greenhouse

There are several reasons why growing peppers in a greenhouse is a good idea. Here are some of the benefits of mini greenhouse gardening:


Protect your plants from pests and diseases

Flea beetles, cutworms, aphids, corn borers, and whiteflies are some of the bugs that harm your peppers. Aside from the bacterial leaf spot, other diseases like southern blight, powdery mildew, and the mosaic virus can also be detrimental to your plants. Placing them in an enclosed greenhouse lowers the risk of attracting pests and other infectious diseases.


Keep your plants safe from unpredictable climates

Storm, blizzard, excessive heat, and strong winds can easily wipe out your entire garden. It’s hard to grow crops in unpredictable climates, but it isn’t impossible. A mini greenhouse makes it easier for gardeners to grow crops regardless of the weather outside. This means that even if it’s snowing, you can continue to grow crops. (However, you may need supplemental materials like grow lights and insulation.)


Start planting early

Did you know that you can use mini-greenhouses to start plant growth early? You can start planting your seeds and seedlings even before the cold season begins in your area. Once the weather clears and warms, you can transplant your crops into your garden and enjoy an early harvest.


Perfect for people with limited garden space

If you’re into gardening, but you don’t have a backyard, a small greenhouse is a perfect solution. You can grow almost anything, plus, they’re compact and convenient. Even though it’s small, mini-greenhouses offer the same benefits as larger greenhouses.


Final Thoughts on How to Cure Bacterial Leaf Spots on Peppers

To recap on how to cure bacterial leaf spots on peppers, the first thing you need to know is that it isn’t curable if the symptoms are starting to spread. However, it is definitely preventable. Remember to plant resistant pepper varieties and make sure the seeds are clean and free of diseases. Isolate your transplants before you plant them in your garden and check if they have any symptoms of any type of disease.

How To Prevent Root Rot In Hydroponics: 3 Useful Tips

If you’re a newbie gardener who’s looking to find ways to hone your skills, you’d want to learn how to prevent root rot in hydroponics even before this problem affects your plants.

Hydroponics can be advantageous to crops in more ways than one. However, it also comes with risks of diseases, such as root rot, which can be destructive or even lethal to your plants.

Unfortunately, there are no effective methods to recover the wilted parts that were affected by the root rot once it hits your plants. The only thing you can do if you do not want this catastrophe to befall your crops is to prevent it before it happens. Read on to learn more about this subject.


What is Root Rot?

Root rot is a disease that attacks the plant roots and causes them to suffer decay. This usually happens when a lack of oxygen supply occurs in the substrate.

To give you an idea, think about plant roots that are submerged in water that only has a little oxygen in it. Over time, the plant suffocates and dies.

Aside from rot and decay, this disease also leads to the proliferation of fungi that are naturally present in the soil. These include Rhizoctonia, Alternaria, Pythium, Botrytis, Fusarium, or Phytophthora. As soon as fungi colonies start to grow, they tend to target the weakened roots and infect your precious plant babies.

Once the plant becomes infected, they won’t be able to take in what they need to grow – water, oxygen, and other nutrients. When this happens, it won’t be long before the plant dies.


What is Hydroponics?

In case you’re not aware, the term hydroponic is derived from a Latin word that means “working water”. To put it simply, hydroponics is an art that involves growing various types of plants without soil. If you’re like most people, the first thing that comes to mind when somebody talks about hydroponics would be a picture of plants with roots suspended into the water without using any type of growing medium.


Avoiding Root Rot in Hydroponic Systems

Detecting and identifying root rot can be tricky. When your plants get infected, their leaves and roots gradually wither until the whole crop itself dies from the lack of nutrients, which is a common symptom of many diseases.


What causes root rot in hydroponics?

One of the requirements in hydroponics systems is oxygen. Without it, your plants are basically on the road to death. On the other hand, lack of such is one of the major triggers for root rot, and it must be avoided at all costs.

Just like when planting in soil, you loosen up the ground so that your plants’ roots can have their required intake of oxygen. That is the case for crops grown in aqueous solutions as well. If they cannot breathe, they would not be able to grow.

Another agent for root rot is the temperature. The last thing you would want in your system are parasites that leech nutrients intended for your plants and infect the water during the process. In common terms, these fungi are called molds.

One of the best breeding grounds for these is warm and moist areas. For this reason, if the water temperature inside your reservoir is high, then you are susceptible to it. Something as minor as letting the solutions exposed to sunlight can already be a risk factor.


3 Useful Tips on How to prevent root rot in hydroponics

There is good news! Root rot in hydroponics can be prevented! Just follow these tips:

Tip#1: Use the right air pump

If you do not want root rot to affect your plants, you merely have to avoid its causes. If you need oxygen, keep the water bubbling by providing an air pump of appropriate size, and also give importance to proper ventilation in the room.


Tip #2: Maintain the temperature

The temperature should be maintained within the 70 to 80 degrees F range. Get rid of any materials that can make your system vulnerable to infections, and make sure not to disturb your crops while they are trying to grow.


Tip #3: Get rid of the rotten parts

However, if you failed in preventing the disease, then the rotten parts should be removed immediately. Cut them off as there is no chance of reviving them, and focus on the potential new growth instead. Fix your hydroponics system and eliminate the risks.


Why Give Greenhouse Gardening a Try?

Greenhouse gardening offers numerous benefits to greens aficionados who dare to take their gardening experience to the next level. Aside from acting as a shield against the effects of inclement weather, a mini, hobby, or semi-pro greenhouse can also serve as a protective layer that keeps harmful bugs and critters at bay.

What’s more, its enclosed structure allows you to control your plants’ growing conditions including the temperature, light, moisture, and ventilation of the greenhouse’s internal environment. With a controlled environment, you’ll be able to extend growing seasons and grow plants that aren’t native to your area.



No matter how well-informed you are about how to prevent root rot in hydroponics, you cannot completely eradicate the risks. Therefore, to avoid the worst-case scenario, you should be prepared to sacrifice the infected for the sake of others. While you’re at it, consider trying your hand at greenhouse gardening as well.
