Are Jalapeño Plants Self-Pollinating?

Jalapeño plants are self-pollinating. The jalapeño plant's flowers contain pollen that can be used to fertilize itself. While a jalapeño plant can fertilize itself, it doesn't have to since it's also receptive to pollen from other jalapeño plants.

While it isn't required for the plant to produce, jalapeño plants prefer pollen from other jalapeño plants. One way the jalapeño plant shows a preference for pollen from other jalapeño plants is how its flower is built.

The style of a jalapeño plant's flower is set higher than the pollen-covered anthers to increase the odds of receiving pollen from other plants. The flower's stigma is also ready to receive pollen before its own pollen is fully prepared so it can increase further the odds of getting different genes.

The reason that jalapeño plants prefer pollen from other jalapeño plants is that it increases biodiversity. When a population of plants has increased biodiversity, it's more likely to survive changing conditions.

Jalapeño plants that opted to prefer pollen from other jalapeño plants were more likely to survive and so passed on their genes.

Jalapeño plants are also self-pollinating because while having biodiversity is essential, it isn't as crucial as producing viable offspring. If a jalapeño plant isn't near another for cross-mating, it will pollinate itself.

Why Are My Jalapeño Plants Not Producing?

There are a few reasons that your jalapeño plants may not be producing. Let's look at the most common causes for jalapeño plants not producing and how to remedy them.

Underwatering Or Overwatering

If you are underwatering or overwatering your jalapeño plants, they may not produce peppers. There are different signs to tell if you are underwatering or overwatering.

If you are underwatering, then the ground will be dry, and the plant will look wilted and thin. The thin look of the plant is due to it not having enough water to grow bushy leaves or peppers.

To fix underwatering, increase the amount of time you water your pepper each watering day by a few minutes. You may also need to add additional watering days each week. Be sure to add watering time gradually to avoid overwatering.

If you are overwatering your jalapeño plants, the ground is spongy and soaked, and the plant looks yellow and sick. When there is too much water in the ground, the plant will not be able to breathe well and will start suffocating.

When the pepper plant is in these sick conditions, it will not produce peppers. The solution to overwatering is to stop watering for a few days to let the soil dry out and then resume watering with decreased watering times.

If you see your jalapeño wilting with decreased watering times, slightly increase it until the plant responds positively.

Too Hot Or Cold Temperatures

If it is too hot or cold outside, your jalapeño plant may have difficulty producing. There are different signs for hot and cold temperatures, so let's look at them for both hot and cold and see what can be done to help.

It may be too hot if you see that your pepper plant is losing all its blossoms. One solution is to transfer your pepper plant to a pot and bring it inside.

If temperatures are too cold for your jalapeño plant, it will not grow quickly and may not produce flowers. Just like with hot temperatures, the solution is to bring your pepper plant inside to milder temperatures.

Too Much Or Little Fertilizer

If you don't have the right amount of fertilizer, it can drastically affect your jalapeño plants. Let's look at how having too much or too little fertilizer can prevent your jalapeño plants from producing and how to remedy it.

If you have too much fertilizer, then you will start noticing your jalapeño plant stressing and the ends of its leaves turning brown.

When this happens while the plant is blooming, it can kill the blossoms and prevent them from producing. If you see signs that your jalapeño plant is stressing from fertilizer, you need to flush it out.

You can flush out excess fertilizer by soaking the ground with a hose for an hour and then allowing the area to dry for a day or two. The water will flush out the fertilizer, reducing it in the soil.

If you have too little fertilizer, then you will find your jalapeño plant is thin and won't produce flowers. This is because it doesn't have the nutrients to grow peppers. Add a few tablespoons of triple fertilizer around the base of your pepper plants, and in a few weeks, they will bloom.

If you are looking for the right fertilizer containing all three vital nutrients for healthy plant growth, here are two of the best products on Amazon.

There are three main reasons that your jalapeño plants may be dying. The leading causes of dying jalapeño are overwatering, underwatering, and overfertilizing. Let's learn how to identify each of the problems and how to solve them.

Overwatering

If you are overwatering your jalapeño plants, you may notice that they are turning yellow and dying. The ground will also be saturated with water. The solution for overwatering is to stop watering for a few days and allow the soil to dry.

If you notice white or black spots on the leaves of your jalapeño plants, they may have a fungal or bacterial infection. These infections can be brought on by wet conditions and can't be cured by simply allowing the ground to dry. If you see signs that your jalapeño plant has one of these infections, you will want to treat it.

If you have a bacterial infection, you will need to treat your plant with a bactericide; if it's a fungal infection, you will need a fungicide.

While typically, white spots mean a fungal infection and black spots indicate a bacterial infection, it would be best to buy a plant spray that treats both fungal and bacterial infections to ensure it is adequately treated.

If you are looking for a plant spray to treat both fungal and bacterial infections, here are two of the best available on Amazon.

Underwatering

If you see that the ground is dry and your jalapeño plant looks wilted, you are underwatering. To remedy underwatering, you need to increase water times gradually. It's vital not to increase watering times too fast to avoid the myriad of issues with overwatering.

Overfertilizing

Overfertilizing is the most direct cause of sick jalapeño plants to identify because it will always occur a day or two after fertilizing. If you see that the ends of your jalapeño plants are turning brown and dying, you will need to flush the ground.

As mentioned before, use a garden hose to flush the ground for several hours. Allow the soil to dry for a few days to keep any fungal or bacterial infection from setting in.

How Do You Grow Jalapeño Plants From Seed?

To grow jalapeño plants from seed, you must first plant the seeds in potting soil. Keep the seeds indoors and ensure they get lots of light. Warmer temperatures encourage the seeds to sprout.

Either put the plants in a window with plenty of light, or use grow lights. If you would like to buy some grow lights to help grow jalapeños from seeds, here are two of the best available on Amazon.

It's also vital to keep the seeds moist since, if the seedlings dry out at any point, they may die. Keep watering the seeds every four to six hours to ensure they don't dry out. While you should keep the seeds moist, be sure not to soak them, as doing so may drown them.

After six to eight weeks, the plants will be ready to be transferred outside. Once the plants are transferred to the garden, they need to water a few times a week.

It is also helpful to spread a small handful of fertilizer around the base of the young plants. Any fertilizer that contains an even mix of nutrients will work.
