Starting Hot Pepper Plants From Seed

Hot Pepper Saplings - Pepper Joe's

Getting Started

Growing your own hot peppers from seed can be very rewarding. The selection of hot peppers available at the supermarket is very poor. Although the selection of plants from a nursery or store is a little better, when you start from seeds, there is a terrific variety available. And as hot pepper popularity is growing constantly, the varieties just keep expanding. So for starters, pick out your selections.

I LOVE this part. It's a blast in the dead of winter to plan out your garden, ordering tried and true seeds. But we're all addicted to trying out new, different and exciting variations. I'll give you some input to fit your different needs and preferences in a just a little bit.

Making the Process Easy

If you live in a year-round warm climate, such as southern Florida, you can direct-sow your seeds into your garden. If you have a greenhouse, good for you!

The majority of my customers don't fit into these two categories, so I'll tailor this article towards them, although the same basics apply. I prefer a plain and simple approach that gets results. There are a few different methods to germinate seeds.  We recommend the Wet Paper Towel method.  Another way to start is with soil and trays. Both are detailed below. 

Soil and Tray Method:

Some seed varieties can be finicky to germinate. I recommend soaking seeds overnight in warm water to give them a head start. I am a 100% organic gardener, but of course there is many people are not. Some of them soak the seeds overnight in Saltpeter (potassium nitrate). (When sowing outdoors, the Saltpeter actually simulates the digestive tract of birds that eat wild hot peppers, therefore accelerating germination.)


There are many good seed starting mixes available at nurseries or discount stores. They work very well and I would recommend them as there is no mixing, measuring, etc. If you prefer to make your own mixture, go with 1/3 good garden soil (don't go with clay soil as it compacts badly), 1/3 composted cow manure or similar growing medium, and 1/3 sand. Hot pepper plants LOVE sand as many varieties originate in areas with sandy soil. Also it provides excellent drainage. Mix all 3 ingredients together very well.


I like plastic gro-packs for 6 to 12 plants, peat pellets or peat pots. Gro packs are especially good because you can cover tightly with "cling-wrap" after first watering and create a little "hothouse" environment. The soil stays moist longer at a higher temperature. Just remove cling-wrap when seedlings emerge. Put your soil/seedling mix into containers. Don't fill to exact top but leave at least 1/4 inch for watering or it will run off.

Then sow seeds 1/4 inch deep 6 to 10 weeks before the last frost. Keep seeds moist, but not soaked, through germination phase. They germinate best above 65 degrees. Ideal is 75 to 85 degrees. Because most homes are not this warm, another tip is to place them on top of your refrigerator until seedlings emerge. It stays pretty warm there. Don't forget my cling-wrap tip in a sunny windowsill.

Again, be patient, some varieties can take 4 to 6 weeks to germinate. Others can show up in 7 to 10 days. It depends on temperature,sunlight, soil and variety. After they emerge I believe in the mother nature theory: "Survival Of The Fittest". I plant 3 or 4 seeds per growing area.

Paper Towel Method:

Let tap water sit 24 hours to evaporate chlorine.  Use gloves, re-seal-able bags and paper towels.  Label your bags and lay out a paper towel square.  Spray paper towel to dampen.  Sprinkle and spread seeds on half the paper towel and fold over.  Lay paper towel in zip lock bag.  Seal, leaving and 1" to let in oxygen.  Place in a warm (80-85 degrees) area with moderate light. Keep paper towels damp. Germination can take anywhere from a  few days to a month. Once they develop a small tail or sprout, the are ready to transfer to indoor soil or a green house.

Find a good and warm sunny windowsill. Seedlings prefer at least 6 hours of sunlight, the more the better. Hot pepper seeds need to be coaxed through the germination and transplant stages. Remember they all originated from a tropical environment. But keep in mind you'll be rewarded with a healthy, robust, prolific plant for your patience.

As they develop their first set of leaves I'll snip off with a scissors the weakest one. As they develop their second set of leaves I'll snip off all but the healthiest one. If any variety starts to grow tall and too "leggy", open the window just a little bit to shock the plant with cooler air. This will slow down its growth and make its stem thicker and more conducive to transplant. Once you have healthy seedlings you're ready for the transplant and growing stage, then the harvesting stage, then my favorite the cooking and eating stage.
