Jalapeno is a variety of Chili pepper which is a member of the Capsicum family. Its botanical name is Capsicum annuum longum group 'Jalapeno'. Jalapeno is generally thought of as a heirloom open-polliated variety. Its fruits normally ripen as a colour very similar to   Cadmium green and   Fire engine red. Leaves usually appear in   Cal Poly green colour.

The Jalapeno chili is a medium sized, glossy green chili pepper that turns red when ripe. This variety is particularly productive and for this reason is one of the most popular chilis to grow in home gardens. Jalapeno chillies taper to a blunt end and grow to be around 7.5cm long and 3cm in diameter.

Jalapeno grows as an Annual and is a Vegetable. Being an Annual, it tends to grow best over the course of a single year. Jalapeno normally grows to a max height of 2.93 feet (90.0 cm metric).

Mexico is believed to be where Jalapeno originates from.

Jalapeno Chili pepper is normally fairly low maintenance and quite easy to grow, as long as a level of basic care is provided throughout the year. Being aware of the basic soil, sun and water preferences will result in a happier and healthier plant.

How to grow Jalapeno

  • Full Sun

  • Medium

Some varieties may need to be supported with a cane or cage as the fruit develops.

Plant in a location that enjoys full sun and remember to water moderately. Jalapeno is generally regarded as a tender plant, so remember to wait until your soil is warm and the night time temperature is well above freezing before moving outside. USDA Hardiness Zone 5 to 12 are typically the USDA Hardiness Zones that are appropriate for this plant (although this can vary based on your microclimate). Jalapeno needs a loamy and sandy soil with a ph of 7.0 to 8.5 (neutral soil to weakly alkaline soil).

Growing Jalapeno from seed

Sow chilli seed 6mm deep into seedling pots. Use liquid fertiliser once germinated.

Try to aim for a seed spacing of at least 1.95 inches (5.0 cm) and sow at a depth of around 0.2 inches (0.5 cm). For optimal germination, soil temperature should be a minimum of 18°C / 64°F.

By our calculations, you should look at sowing Jalapeno about 38 days before your last frost date.

Transplanting Jalapeno

Transplant out when all danger of frost has passed. Transplant when soil is warm. Give moderate fertiliser and water. Avoid high nitrogen fertilisers as these will promote leaf growth at the expense of fruit.

Jalapeno is tender, so ensure you wait until all danger of frost has passed in your area before considering planting outside.

Harvesting Jalapeno

How can I tell if my jalapeno peppers are ripe?
You should be able to tell if your jalapeno peppers are ripe by their colour and size. They should appear to be a deep green colour and should be around 3 inches / 8 cm in length when they are first ready to be picked. If they are picked when green, Jalapenos will have a crisp texture and will be quite mild. If you leave the chili to ripen a little longer it will eventually turn red and have a much hotter flavour.

This variety tends to mature and be ready for harvest in late summer.
