Jalapenos are one of the most popular peppers to grow at home and for a good reason. They have a fresh and spicy flavor that adds a kick to any dish. You can use them fresh, dried, pickled, or smoked.

This article will go through the seven jalapeno growth stages, from seed to harvest. We will also give you tips and recipes for using your homegrown jalapenos in various dishes. Let’s get started!

Like every gardening journey, the story of a jalapeno pepper begins with a tiny seed. As the seed awakens and germinates, it transforms into a young jalapeno plant. Once the plant flowers and those blossoms are successfully pollinated, it produces fruits. As it matures, this fruit transitions in color, often appearing green or red, depending on the variety. At this stage, your jalapenos are ready for a harvest.

The complete lifecycle of a jalapeno plant spans 80 to 126 days, from the initial seed sowing to the harvest. The actual number of days can vary based on the specific variety and the growing conditions.

Now, let’s explore each of these jalapeno growth stages in more detail.

Stage 1. Seed Sowing

The first step of jalapeno growth is seed sowing. It is best to sow jalapeno seeds indoors, in pots, a few weeks before the final frost date. This allows for a head start and better prepares your jalapeno plants for outdoor transplantation.

To sow jalapeno seeds, place two or three seeds in a single hole approximately 1/4 inch (0.6 cm) deep. Placing multiple seeds into one hole increases the chances of successful jalapeno seed germination.

Place the pots in a warm, well-lit area and provide sufficient watering. This will cause the seeds to sprout within 7 to 15 days.

Stage 2. Germination

The second stage of jalapeno growth is seed germination, which is when the seeds sprout and produce the first roots and the first set of leaves.

Jalapeno seeds usually take 7 to 15 days to germinate, but this can vary depending on seed quality and environmental conditions. Eventually, the first true leaves will form, which look like the mature leaves of the plant. At this stage, your jalapeno plants are still very fragile, but as the seedlings grow, they will produce more sets of true leaves, and the plant will become stronger and taller.

If you are growing your jalapeno seedlings in pots, transplant them to their final destination when they have 3 to 4 sets of true leaves. This will give them more room to grow and prevent root-bound problems.

To transplant your jalapeno seedlings, carefully remove them from their pots by gently squeezing the sides of the pot. Do not pull them by their stems or leaves, as this can damage delicate plants.

Dig a hole for each plant slightly larger than the pot and place one plant in it. Fill the hole with soil and press it firmly around the base of the plant. Water all plants well and mulch them with straw or wood chips to conserve moisture and prevent weeds.

Stage 3. Vegetative Growth

The third stage of jalapeno plant development is the vegetative growth phase. That is where jalapeno plants undergo significant expansion. They grow taller and wider, producing multiple branches and lush foliage. The plant’s dimensions typically reach a height of 24 to 36 inches (61 to 91 cm) and a width of up to 18 inches (46 cm), depending on the specific jalapeno variety and growing conditions.

During the vegetative growth phase, jalapeno plants grow rapidly and produce many branches and leaves as they prepare to produce flowers and support pepper fruits at a later stage.

Stage 4. Flowering

Once the jalapeno plant has reached a certain stage of maturity, it will begin to produce flowers. These flowers are typically white, star-shaped, and grow in clusters at the nodes of the stems. Nodes are the points where leaves or branches attach to the stem.

The formation of flowers is a complex process influenced by several factors, including genetics, environmental conditions, and the availability of nutrients. In general, the flowering process begins with the development of flower buds. These buds are located at the nodes of the stems and contain the developing flower petals and reproductive organs.

As the flower buds mature, they open to reveal the star-shaped flowers. The flowers are self-fertile, meaning that they can pollinate themselves. However, insect pollination can also occur, leading to increased fruit production.

Stage 5. Pollination

Pollination is the process of transferring pollen from the male reproductive organ (stamen) of a flower to the female reproductive organ (pistil) of a flower. This process is essential for fertilization and fruit production in jalapeno plants.

Pollination can occur in two ways: self-pollination and cross-pollination:

  • Self-pollination occurs when pollen from the stamen of a flower is transferred to the pistil of the same flower.
  • Cross-pollination occurs when pollen from the stamen of one flower is transferred to the pistil of a different jalapeno plant flower.

Cross-pollination is generally more beneficial for jalapeno plants, as it can lead to increased fruit production and genetic diversity. However, self-pollination is also possible, especially in indoor or greenhouse environments.

Pollination in jalapeno plants is typically carried out by insects, such as bees, hoverflies, and butterflies. These insects are attracted to the bright colors and sweet nectar of the flowers. As they visit the flowers, they collect pollen on their hairy bodies. When they visit another flower, the pollen is transferred to the pistil, resulting in pollination, which leads to fertilization and jalapeno pepper fruit production.

If you are growing jalapeno plants outdoors, you can encourage pollination by planting flowers that attract beneficial insects.

Pro Tip: You can also hand-pollinate your plants by gently transferring pollen from the stamen of one flower to the pistil of another flower using a small brush or swab.

Stage 6. Fruit Development

Once the jalapeno flower has been pollinated, it will begin to form a fruit. The fertilized pistil swells during this stage and develops into a jalapeno pepper.

As the jalapeno fruit continues to grow, it accumulates nutrients and water, and its outer wall develops a thick, waxy coating that protects it from pests and diseases. The pepper also begins to ripen and change color during this time. As the fruit ripens, it develops a sweeter flavor and a more intense heat.

Stage 7. Harvesting

The seventh and final stage of jalapeno growth is harvesting. Harvesting jalapeno peppers is easy, and you can enjoy them in your favorite dishes immediately.

You can harvest jalapeno peppers at any ripeness level, depending on your preference and taste. Green jalapenos are milder and crunchy, while red jalapenos are hotter and sweeter. To harvest, cut the stem of the fruit with a sharp knife or scissors, leaving a short stem attached to the fruit.

Pro Tip 1: Gloves are important because jalapeno peppers contain capsaicin, which is the compound that gives jalapeno peppers their heat and can irritate your skin, eyes, and mucous membranes. To avoid this, wear gloves when handling jalapeno peppers and wash your hands thoroughly after harvesting. [1]

Pro Tip 2: Place the harvested peppers in a basket or a bowl and avoid stacking them too high, which can cause bruising and eventually rotting.

Jalapeno Pepper Storage

You can store jalapeno peppers in different ways, depending on how long you want to keep them and how you want to use them. Here are some of the most common methods of storing jalapeno peppers:

  • Refrigerating – up to 2 weeks.
  • Pickling – up to 6 months.
  • Freezing – up to a year.
  • Drying – up to 2 years.

Now, let’s discuss each storage method in more detail.


You can refrigerate jalapeno peppers for up to two weeks. This is the easiest and quickest method of storing jalapeno peppers. You can store whole jalapeno peppers in the refrigerator for up to two weeks, while chopped or sliced ones only last a few days.


You can make jalapeno pickles by slicing the jalapeno peppers and placing them in a jar with vinegar, water, sugar, salt, garlic, dill, mustard seeds, and other spices. Keep the jar in a cool place for at least a week before enjoying your jalapeno pickles. You can keep tightly sealed pickled jalapeno peppers for 6 months.


You can freeze jalapeno peppers for up to a year. This is a suitable method for long-term storage, but it changes their texture. Freeze jalapeno peppers whole or sliced, with or without seeds.


You can dry jalapeno peppers in a dehydrator or oven for long-term storage. This is an excellent method to preserve flavor and heat but requires more time and equipment. Dry jalapeno peppers whole or sliced, with or without seeds. You can store dried jalapenos for up to two years.
