Before we start talking about the solutions, let’s have a look over the problems first. Here is a list of the possible reasons turning your Jalapenos black:

  • Blossom end rot
  • Black rot
  • Anthracnose Infection
  • Mosaic virus
  • Natural causes

Now, let’s get to know the problems in a detailed manner and how could you possibly fix this.

Problem 1: Blossom End Rot

Generally, members of the nightshade family which include peppers and tomatoes (Solanum lycopersicum L.) are frequently attacked by Blossom end rot. So, what will tell you that your plant is facing exactly this issue?

Well, signs like a moldy looking spot at the blossom end of the pepper (that turns black over time) will imply that the reason behind it is Blossom end rot. Now, the question is why does this happen?

No, this is not caused by any infections. Improper watering, adverse weather conditions, or calcium deficiency can lead to this trouble.

Solution: To preserve the soil’s moisture, mulching around the Jalapeno plants will help. But if the soil’s pH is below 6.0, the soil may create an imbalance of calcium and it prevents the pepper plants from properly absorbing water from the soil.

To solve this problem, amend the soil with Limestone until the pH is above 6.0. But, sorry to say that it will not reserve the condition on affected peppers, you have to discard those from the plants.

Problem 2: Black Rot

Black rot will affect your Jalapeno peppers in case you leave them on the plant to ripen until they turn red. You may be confused thinking of how you will distinguish it from blossom end rot.

Actually, Black rot affects fully ripened black peppers as well as covers part of the pepper other than the blossom end. The cause leading to this is too much moisture. Yes, if there is too much moisture from excessive watering or rain around ripening Jalapeno plants, Black rot can rear its ugly head.

Solution: To prevent black rot, only water the soil at the base of the plant so that the fruit is kept dry during watering. If you want red peppers, do not leave the peppers on the plant too long after they have fully ripened. Most importantly, discard any jalapenos that are victims of black rot.

Problem 3: Anthracnose Infection

This one causes parts of jalapeno peppers to turn black. But you can easily differentiate it from blossom end rot as in this case, the black areas will be along the sides of pepper rather than the end.

Actually, a fungus causes the watery bruises that are common with anthracnose. By degrees, these spots may appear on the leaves, stems, or peppers of the plants. Moreover, they will progress to become black spots where they develop.

Solution: A bad news is there is no means to correct an anthracnose infection on your jalapeno peppers. You can prevent it only if you plant seeds from a reputable source.

Another point worth noting is, you can’t plant in the same bed where any other member of the nightshade family who was affected by anthracnose grew within the last two years.

Remove weeds regularly and keep the garden area neat and clean to seal the chances of happening this in the future.

Problem 4: Mosaic Virus

Mosaic viruses will prevent your jalapeno plant from producing properly ripened, fully formed peppers. The affected peppers usually have darkened areas on them as well as look smaller than the unaffected peppers.

Other telltale signs are curled leaves with both light and dark green areas and a reduced growth of the plant.

Solution: Here’s another unwanted announcement, there is no treatment. What you can do is to prevent this variety of viral infections in your pepper plants and keep them from spreading through your garden.

You can lay down foil for mulch around your pepper plants. It will help your plants to prevent virus-carrying insects from reaching them. Besides, it will be helpful to pull out the entire plants that show symptoms of a viral infection and discard them to keep the infections from spreading.

Problem 5: Natural Causes

If none of the above happened to your jalapeno plants, then it can be natural. Yes, jalapenos turning black on the plant is a part of their natural growth and ripening process.

So, examine carefully whether your jalapenos are struggling with the above-mentioned 4 issues or it’s quite natural.
