Cubanelle peppers are sweet, measuring between 4 to 6 inches long, with unique shapes. They transition from green to red and have a lower water content than other peppers. They are ideal for frying and cooking.
About 8 weeks before the last expected frost, sow your peppers in peat pots. Plant the seeds at a depth of 1/4 inch and maintain the room temperature at around 80°F (25°C). When all risk of ground frost is eliminated, transplant the pepper plants into the garden, keeping a distance of 12 inches between each plant. Mulching the plants can help control moisture and weeds. If the plants wilt due to the sun, you can provide them with shade.
The longer the peppers stay on the vine, the sweeter they will taste. Harvesting will be mainly a matter of personal preference regarding color and sweetness. However, ripe peppers signal the plant to stop producing new vegetables. Pick them green, and your production will continue.
