Growing jalapenos is both rewarding and fun, as they add a ton of flavor to any dish and are fairly easy to grow. Today we'll show you how to grow jalapeno plants (jalapeño plants) right in your garden or in a pot or container. Jalapenos start off slow, but once they get growing, there's no stopping them!
Growing jalapenos is not hard as long as you follow some of the key instructions. One of the most important things to keep in mind when growing jalapenos, is to give them lots of sun and heat. Jalapenos prefer weather between 80-85F (26-29C), and plenty of sun. Be sure to wait before growing your jalapenos – all danger of frost has to have been gone before planting. Hot peppers and regular bell peppers are all usually grown in the same manner. They all need heat, sun, and regular watering.
The jalapeño pepper plant is a member of the hot pepper family and is actually the only pepper variety that is not allowed to fully ripen before being picked. It's a medium sized chili pepper cultivar of the species Capsicum annuum. A typical jalapeño pepper is about 2-4 inches long (5-10cm) and hangs down with a round, firm, and smooth flesh. The fiery pepper plant can have a Scoville heat unit of anywhere from 3,500 to 3,600. For the most part, the jalapeño pepper plant is picked while green, but it can also be left to turn yellow, orange, or red.

Planting Jalapenos:
- For best results, start seeds indoors. You can find jalapeno pepper seeds at your local nursery or online.
