How To Plant, Grow, & Harvest Jalapenos

Jalapenos are tasty green peppers with a mildly earthy, peppery flavor. They are frequently used to flavor food are commonly pickled. Other intriguing names for this pepper are chile gordo, huachinango, and cuaresmeno, which each refer to various characteristics of the jalapeno. 

The height of a healthy jalapeno pepper plant can reach 2-3 feet (24–36 inches). Jalapeno pod production per plant might range from 25 to 30. The ripe pods have a dark green appearance. They turn red and eventually purple if they are kept on the vine for a longer period of time.

We all know that jalapeno peppers have a pleasant, tasty heat, but how hot are they exactly? They range from 2500-8000 Scoville heat units overall. This makes them feel pleasant and warm, though not as fiery as other peppers in the same family like the ghost or habanero.

The jalapeño plant has white blooms from which the jalapeno peppers emerge. The silky, dark-green leaves of some cultivars, like the purple jalapeño, have a purplish tint on both the stems and the leaves. 

The fruit will be between 2-4 inches long when it is fully grown, and it will initially be either dark green or purple. They will eventually dry out after turning dark and then gradually crimson as they deteriorate on the plant. Read on to learn about how to grow jalapeno peppers!

Growing Conditions For Jalapenos

Light & Temperature

Jalapeno plants need full sun to produce the best peppers. If you live in an area with hot summers, your jalapenos will do best in afternoon shade. The ideal temperatures for growing jalapenos are 70-80 degrees Fahrenheit during the day and 60-70 degrees Fahrenheit at night. 

If temperatures get too hot, the peppers will stop growing and turn red prematurely. If temperatures get too cold, the peppers will take longer to mature and may not have as much flavor. 


Jalapeno plants need well-drained, fertile soil in order to thrive. The ideal soil for a jalapeno plant is loose and sandy, with a pH level between 6.0 and 7.0. If your soil is too heavy or clay-like, you can add organic matter such as compost or peat moss to loosen it up. You should also make sure that your soil has adequate drainage; jalapeno plants will not tolerate soggy conditions. 

To test your soil's drainage, simply dig a hole about 12 inches deep and fill it with water. If the water drains away within 24 hours, your soil is suitable for growing jalapenos. If not, you will need to take steps to improve the drainage before planting. Amend your soil with perlite, vermiculite, or sand. These materials will help to create pockets of air in the soil, which will promote better drainage.


Jalapeno plants need plenty of water to produce healthy peppers. During the vegetative stage, when the plant is focusing on growing leaves and stems, it will need about 2 inches of water per week. Once the plant begins to produce flowers and fruit, it will need even more water, about 3-4 inches per week. 

To ensure your jalapeno plant is getting enough water, check the soil regularly. It should be moist but not soggy. If it feels dry to the touch, give the plant a deep watering. Overwatering can also be a problem, so be sure to allow the soil to dry out somewhat between watering.

Nutrients & Fertilizer

Some plants are quite particular about the nutrients they need to thrive, and the jalapeno plant is no exception. In order to produce healthy peppers, it is important to provide the plant with a balanced fertilizer that includes nitrogen, phosphorus, and potassium. 

These essential nutrients can be found in both organic and chemical fertilizers, but it is important to choose one that is specifically designed for use on chili peppers. Otherwise, you run the risk of over-fertilizing and damaging the plant. 

Once you have selected a fertilizer, apply it according to the manufacturer's instructions. In general, it is best to fertilize jalapeno plants every two weeks during the growing season. 

How Long Do Jalapenos Take To Grow?

 Jalapenos typically take around 80 days to reach maturity, but this can vary depending on the climate and growing conditions. The best way to determine when jalapenos are ready to harvest is to check the color of the peppers. 

Jalapenos start out green and then turn red, orange, or yellow when they are ripe. Once the peppers have reached the desired color, they can be picked and used fresh or cooked in recipes. With a little care, homegrown jalapenos can provide a tasty addition to any meal.

How To Grow Jalapenos From Seeds

Eight to ten weeks prior to the anticipated last frost date, start seeds indoors in a tray of moist seed-starting mix. During the germination stage, expose the tray to 16 hours of artificial light, and make sure the soil temperature stays between 65 and 80 degrees Fahrenheit.

Temperature regulation may be aided by a seedling heating mat. It may take two to three weeks for germination. Maintain the soil's moisture level for the seedlings. Put the seedlings in a larger container with potting soil once they have two pairs of true leaves. 

They can be put in the garden after being hardened off for two weeks, during which time they are gradually exposed to outside circumstances until they are 6 to 8 inches tall.

How To Grow Jalapeno Peppers

Jalapenos are a type of chili pepper that originated in Mexico. They are a popular ingredient in many cuisines, and can be used fresh, canned, or pickled. If you want to add some spice to your cooking, planting jalapenos is a great way to do it. Here are some tips for planting jalapenos:

  • Choose a sunny spot. Jalapenos need full sun to produce peppers, so choose a spot in your garden that gets at least 6 hours of direct sunlight each day.
  • Prepare the soil. Before planting, work some compost or other organic matter into the soil to help improve drainage. Jalapenos prefer soil that is slightly acidic, with a pH of 6.0 to 7.0.
  • Sow the seeds. Plant jalapeno seeds ¼ inch deep in rows that are 18 to 24 inches apart. Water the seeds well and keep the soil moist until they germinate, which usually takes 7 to 10 days.
  • Thin the seedlings. Once the seedlings have emerged, thin them so that there is one plant every 12 to 18 inches.
  • Fertilize and water regularly. Jalapenos need regular watering, especially when they are fruiting. Apply a fertilizer every 4 to 6 weeks during the growing season.

Now that you know how to plant jalapenos, all you need is a little time and patience. The most important thing to remember is to keep the soil moist but not too wet. With a little bit of love and attention, your jalapeno plants will thrive. pretty soon, you'll be able to enjoy home-grown peppers in all your favorite dishes.

Harvesting & Storing Jalapenos

After planting, your jalapenos should be ready for harvesting four to six months later. Watch for dark green coloration in your peppers. Jalapeo harvesting takes keen observation. When your jalapeo pepper plants are glossy and between four and six inches long, they are ready to be harvested.

Jalapenos can be picked when they are dark green, but they can also be picked after they turn red. Your jalapenos need to feel solid to the touch as well. Use sharp pruning shears to cut the jalapeo peppers off, leaving a short stem.

Jalapenos should be kept at room temperature for best freshness and consumed within three days. Additionally, you may keep them fresh in the fridge for up to a week, or pickle or freeze your jalapenos to extend their shelf life to several months.

Jalapeno Plant Care & Maintenance

Jalapeno plants thrive in warm, sunny conditions and require little maintenance once they are established. However, there are a few things to keep in mind when caring for jalapeno plants. First, it is important to water them regularly during the growing season. 

They should be allowed to dry out slightly between waterings, as too much moisture can lead to root rot. Second, jalapenos need nutrient-rich soil in order to produce healthy fruit. 

A general-purpose fertilizer can be applied every few weeks during the growing season. Finally, jalapenos require very little pruning. Once the fruit has been harvested, any dead or diseased leaves can be removed.

Common Jalapeno Pests & Plant Disease


One of the most prevalent jalapeno pepper pests is the aphid. These tiny, green or white insects feed on the leaf sap, weakening the plant and increasing its susceptibility to disease. Use harmless pest control techniques whenever possible, such as ladybugs or insecticidal soaps.

Young plants' roots might suffer damage by cucumber beetle larvae. These tiny, black-striped, yellow-green insects bite holes in the leaves. Eliminating the weeds in the region will aid in removing beetle breeding grounds. Greenish caterpillars known as pepper hornworms gnaw sizable holes in leaves. 

The best treatment is manual worm removal. Mites are tiny, practically invisible insects that alter or discolor plants. It is necessary to remove and kill any affected plants.


A fungal disease called fusarium wilt weakens and yellows plants. It will be necessary to uproot and destroy any affected plants. This disease is typically avoided by maintaining healthy, well-watered plants. Another typical fungal disease, anthracnose, causes dark sunken patches on the fruit. When you next plant, be sure to get resistant kinds and remove and destroy any damaged plants.
