In this post, we’ll walk through the entire journey of how to grow jalapenos from store bought peppers, from picking the right pepper to harvesting your very own spicy crop.
Let’s dig into the dirt and get started.
Why You Can Grow Jalapenos From Store Bought Peppers
The reason you can grow jalapenos from store bought peppers comes down to simple plant biology and seed viability.
Jalapeno peppers are self-pollinating, and the seeds inside a ripe pepper are mature enough to germinate if given the right conditions.
When you learn how to grow jalapenos from store bought peppers, you’re essentially unlocking a free source of seeds that are perfectly adapted to your local store’s supply chain.
Here’s the key to success: the peppers you choose matter a lot, and we’ll cover that below.
Start With the Right Pepper
To grow jalapenos from store bought peppers, you need to select a pepper that is fully ripe, not just green.
Green jalapenos are technically immature, and their seeds are less likely to germinate successfully.
Look for jalapenos that have started to turn red, brown, or even develop small cracks, as these are signs of full ripeness.
A ripe pepper will have seeds that are firm and cream-colored, which is your best bet for a high germination rate.
If you can, buy organic jalapenos, because they’re less likely to have been treated with growth inhibitors that can keep seeds from sprouting.
Extract and Dry the Seeds Properly
Once you have your ripe pepper, the next step in how to grow jalapenos from store bought peppers is to carefully extract the seeds.
Slice the pepper open and scrape out the seeds with a spoon, trying not to damage them in the process.
Lay the seeds out on a paper towel in a single layer and let them dry for about one to two weeks in a cool, dry place.
Drying the seeds is crucial because it prevents mold and prepares them for the germination phase.
After they’re completely dry, you can store them in an envelope or plant them right away.
Steps to Grow Jalapenos From Store Bought Peppers
Now that you have your seeds ready, let’s get into the actual steps to grow jalapenos from store bought peppers successfully.
This process is all about mimicking the warm, moist conditions that jalapeno seeds love.
Follow these steps closely, and you’ll see sprouts in no time.
Step 1: Prepare Your Planting Containers
Start by filling small pots or seed trays with a high-quality seed starting mix.
Moisten the soil before planting so it’s damp but not waterlogged, as jalapeno seeds don’t like soggy conditions.
You’ll want containers that have drainage holes in the bottom to prevent root rot.
Plant your seeds about a quarter-inch deep into the soil, spacing them a couple of inches apart.
Cover the seeds lightly with soil and gently press down.
Step 2: Provide Warmth and Light
Jalapeno seeds need warmth to germinate, so aim for a soil temperature between 75°F and 85°F.
You can use a heat mat underneath your trays to maintain this consistent temperature, which is a huge help when learning how to grow jalapenos from store bought peppers.
Place the containers in a bright location with indirect sunlight, or use a grow light set to run for about 14 to 16 hours a day.
Keep the soil consistently moist by misting it with water whenever the top feels dry.
Germination typically takes anywhere from 7 to 21 days, so be patient and keep checking daily.
Step 3: Care for Your Seedlings
Once your seedlings emerge, they’ll need plenty of light to grow strong and sturdy.
If you’re using a windowsill, make sure it’s a south-facing window so they get maximum sunlight.
As the seedlings grow, thin them out so only the strongest plant remains in each pot.
Start fertilizing them with a diluted liquid fertilizer once they have two sets of true leaves.
When the seedlings have grown to about six inches tall and the outside temperature is consistently above 60°F, they’re ready to be transplanted outdoors.
Transplanting and Growing Jalapenos Outdoors
Growing jalapenos from store bought peppers doesn’t stop at the seedling stage, because these plants need room to spread out and thrive.
Hardening off your seedlings is an essential step before moving them into the garden.
Harden Off Your Seedlings
About a week before you plan to transplant, start acclimating your seedlings to the outdoors.
Place them outside in a shaded, sheltered spot for a few hours each day, gradually increasing their time outside.
This process, called hardening off, prevents transplant shock and helps the plants adjust to wind and direct sun.
After seven days, they’ll be ready for full sun exposure.
Planting in the Ground or Containers
Choose a sunny spot in your garden that gets at least six to eight hours of direct sunlight per day.
Jalapenos love rich, well-draining soil with a pH between 6.0 and 6.8.
Dig holes that are slightly larger than the root balls of your seedlings, and space each plant about 18 to 24 inches apart.
Gently remove each seedling from its pot and place it in the hole, then backfill with soil and water thoroughly.
If you’re growing them in containers, make sure each pot holds at least a five-gallon capacity for optimal root growth.
Ongoing Care for Healthy Jalapeno Plants
Water your jalapeno plants deeply once or twice a week, especially during dry spells.
Mulch around the base of the plants to retain soil moisture and suppress weeds.
Feed them with a balanced fertilizer every four to six weeks to encourage healthy growth and fruit production.
Watch out for common pests like aphids and spider mites, which you can control with insecticidal soap.
As the plants grow, you might need to stake them to support their heavy fruit loads.
Harvesting Your Homegrown Jalapenos
The payoff for learning how to grow jalapenos from store bought peppers comes when you finally get to harvest your own spicy peppers.
Jalapeno plants typically produce fruit about 70 to 80 days after transplanting.
Harvest jalapenos when they reach their mature size, usually about three to five inches long.
You can pick them while they’re green for a milder flavor, or leave them on the plant longer to turn red and develop a sweeter, hotter taste.
Use clean scissors or pruning shears to cut the stems so you don’t damage the plant.
Regular harvesting encourages the plant to produce even more peppers, so don’t be shy about picking them.
