The aji dulce pepper is one of many different kinds of aji peppers, and is most often found in Caribbean dishes. It’s native to this region, more specifically Puerto Rico, Cuba, and the Dominican Republic.

The classification of this pepper is Capsicum chinense, a variety native to the Yucatan Peninsula of Central America and the Caribbean islands. The name ‘aji dulce’ translates to ‘sweet pepper’.

Aji Dulce: Everything About Them

If you’re looking to grow aji dulce peppers, follow this step by step guide.

First, you should mix equal parts compost, potting soil, sphagnum moss, and perlite. Add this mixture to a 12 inch pot until it’s three quarters full. Ensure the pot has good drainage prior to adding the mixture.

You should be starting the seeds two months before the start of the planting season.

Sow the seeds on the surface before covering them with just a sprinkling of soil. Keep them at a south facing window, covered with plastic. Mist the soil regularly in order to maintain its moisture.

Next, plant your seedlings in time so you’ll be putting them out after the last frost. Plant them in the center of the pot, before covering their roots with soil. Water regularly. You may also need to add more soil.

Your potted pepper should be placed in full sun, and you should place a small tomato cage (between two to three inches in height) over the pot. This will support the plant during the growing process. Water daily, but only when the soil needs moisture.
