How long do jalapenos take to grow?

The time it takes for jalapenos to go from seedling to harvest can vary with different growing conditions. Generally speaking, jalapeno plants require 70-80 days of warm weather before they produce peppers ready for harvest.

During this time period, the plant should be kept well watered and fertilized regularly. The pepper will also need to receive adequate sun exposure throughout the day in order for it to ripen successfully and become red or green (depending on variety).

Are jalapenos easy to grow?

You don’t need a green thumb or perfect growing conditions to start – jalapenos are one of the most popular and versatile chili peppers. They’re surprisingly easy to grow in almost any climate. 

Here are some tips to help you easily grow jalapenos.


Most people start their jalapeño pepper plants from seed indoors. The best timing is generally 6 weeks before the last frost. This occurs in the majority of the United States between January and March. If you start your seeds inside, a seedling heating mat might help them germinate faster.


Look for areas of your yard that receive full sun. Peppers adore the sun and will require enough of it to thrive. After you’ve located those areas of the yard, seek one that offers some protection from heavy winds. This will safeguard your plants from being blown over or knocked over.


The optimal humidity level for pepper plants is between 50% and 70%. A greenhouse or humidifier can help keep humidity levels stable. Don’t worry if you live in a less humid location; your plants can also survive reduced humidity. Simply ensure that they have sufficient water to drink.


The soil should be well-drained, loamy, and exceptionally organically rich. The jalapeno plant prefers rich, healthy soil!

If possible, aim for a soil pH of 6.0-6.8. While they may survive in slightly acidic or slightly alkaline environments, neutral conditions are best. If you’re unsure, use a pH test kit to discover the average pH of your soil.


Make sure your seedlings receive sufficient nitrogen shortly after planting to give them a healthy start. This will stimulate the plant’s early development. It is OK to work a slow-release fertilizer into the soil before planting seedlings.


Examine each pepper plant closely as it grows. If it has suckers or stems that appear too thin but have much stronger and thicker ones, pinch off the suckers to encourage greater vigor in the rest of the plant. This also improves pepper output.

Do jalapenos grow well in pots?

Jalapenos are one of the most popular hot peppers, and they make an excellent choice for growing in containers. They grow well in pots, making it easy to cultivate them anywhere–even if you don’t have a lot of space. 

When growing jalapenos in pots, be sure to select a container that is large enough for their root system and has plenty of drainage holes at the bottom. Pots should be at least 10-12 inches deep and filled with good-quality potting soil that has been amended with compost or manure for added nutrients. 

Do jalapeno plants need full sun?

When it comes to planting jalapeno peppers, the amount of sun they receive is important. Jalapenos are generally considered a warm-weather crop and require plenty of sunlight to produce their fruit. For best success, jalapeno plants need full sun for at least 6 hours each day; however, in some regions with very hot summers, providing afternoon shade may be beneficial during the hottest part of the day. 

When choosing a spot for your jalapeno plant, look for one that gets full sun throughout the majority of the day. If you don’t have a spot that gets full sun all day long, you can give your peppers an extra boost by supplementing with grow lights or artificial lighting systems. The more light they get, they will produce larger yields and tastier fruits.

Do jalapenos need lots of water?

In general, jalapenos should be watered twice weekly during their growing season. To determine how much water your plants are receiving, use a soil moisture meter or insert your finger into the soil around the base of the plant; if it’s dry up to one inch deep then the plant is ready for watering. 

During hot weather conditions, you may have to increase watering frequency; when temperatures soar above 90 degrees Fahrenheit, consider watering every other day. Additionally, mulching around your plants can help maintain an even level of moisture by reducing evaporation levels from the soil surface.

How many jalapenos do you get from one plant?

On average, each jalapeno pepper plant will produce 25-35 peppers throughout the season. While this number may vary depending on the variety of pepper, size of the plant and other environmental factors, it is still quite remarkable that one small plant can yield so much edible goodness! 

Additionally, if planted at the right time during the growing season and given proper care, these plants often produce even more peppers than expected. With routine pruning and adequate water supply, gardeners can typically expect 30-50 peppers per plants!
