How to Grow Aji Dulce Pepper

How to Grow Aji Dulce Pepper
  1. Select a spot in your garden that receives full sun, with at least six to eight hours of sunlight per day.
  2. Aji Dulce peppers prefer well-draining soil rich in organic matter. Ensure the soil pH is between 6.0 to 7.0 for optimal growth.
  3. You can start ajicito peppers indoors several weeks before the last frost date in your area or sow the seeds directly into the garden.
  4. Germinate seeds in seed-starting trays and transplant seedlings into the garden or containers once they have developed several sets of true leaves.
  5. Keep the soil consistently moist but not waterlogged. Water deeply, allowing the soil to dry slightly between waterings to prevent root rot.
  6. Apply a balanced fertilizer every two to three weeks to provide essential nutrients for healthy growth and fruit production.
  7. Stake or cage the plants to provide support as they grow. Prune the plants to remove dead or diseased foliage and encourage bushier growth.
  8. Monitor plants regularly for signs of pests and diseases. Treat infestations promptly using organic methods such as neem oil or insecticidal soap.
  9. Aji Dulce(ajicito) peppers are ready for harvest 70-90 days after planting. Harvest ripe peppers as they reach their full size and colour.

Aji Dulce(ajicito) Plants Care

Aji Dulce peppers grow in warm, sunny climates, reminiscent of their tropical origins. To ensure optimal growth and fruit production, it’s essential to provide them with the right care and environmental conditions.

Choose a well-drained soil mixture rich in organic matter for planting Aji Dulce peppers. The soil pH should be slightly acidic to neutral, ideally ranging from 6.0 to 7.0. Select a sunny location in your garden that receives at least 6-8 hours of sunlight daily. Aji Dulce peppers require ample sunlight to develop their characteristic sweet flavour and vibrant colour.

Keep the soil consistently moist but not waterlogged to prevent root rot and other moisture-related issues. Water the plants deeply, ensuring the water reaches the root zone. During hot, dry periods, increase watering frequency to prevent the plants from drying out. Additionally, fertilize the plants regularly with a balanced fertilizer to provide essential nutrients for healthy growth and fruit development.

Aji Dulce peppers thrive in warm, humid climates similar to their native habitat. They prefer temperatures ranging from 70°F to 85°F (21°C to 29°C) for optimal growth. If you live in a cooler climate, consider growing Aji Dulce peppers in containers or starting them indoors before transplanting them outdoors once the weather warms up.

Pruning Aji Dulce Pepper

Pruning is an essential aspect of Aji Dulce pepper plant care that promotes healthy growth, improves air circulation, and enhances fruit production. Proper pruning practices can help maintain plant vigour and reduce the risk of diseases and pests.

Regularly inspect your Aji Dulce pepper plants for any signs of dead or diseased foliage, such as yellowing leaves or black spots. Remove these affected parts promptly to prevent the spread of diseases and ensure the plant’s energy is directed towards producing healthy foliage and fruits.

As Aji Dulce pepper plants grow, they may develop dense foliage that can inhibit airflow and sunlight penetration. Thinning out overcrowded growth by selectively removing excess branches and foliage allows for better air circulation and light exposure, reducing the risk of fungal diseases and promoting even fruit ripening.

Pruning can also be used to control the shape and size of Aji Dulce pepper plants, especially in confined spaces or container gardens.

Common Pests & Plant Diseases

Like all pepper plants, Aji Dulce peppers are susceptible to certain pests and diseases that can affect their health and productivity. To ensure a successful harvest, pest and disease control requires regular monitoring and preventive measures.

Aji Dulce pepper plants may attract various pests, including aphids, whiteflies, spider mites, and pepper weevils. These pests feed on the plant’s foliage and can transmit diseases, leading to stunted growth and reduced fruit production. Regularly monitor your plants for signs of pest infestation, such as yellowing leaves, distorted growth, or the presence of insects, and take appropriate measures to control their populations.

To manage pest infestations effectively, consider employing organic pest control methods such as introducing beneficial insects like ladybugs or lacewings, using insecticidal soaps or neem oil sprays, and practising companion planting with pest-repellent herbs and flowers. Avoid using chemical pesticides that can harm beneficial insects and pollinators and contaminate the environment.

Aji Dulce pepper plants are susceptible to several fungal and bacterial diseases, including powdery mildew, bacterial leaf spot, and damping-off. These diseases thrive in warm, humid conditions and can spread rapidly, causing foliage discolouration, wilting, and fruit rot. To prevent the onset and spread of diseases, maintain proper plant spacing, provide adequate airflow, and avoid overhead watering, which can promote fungal growth.


  1. Select a healthy, non-flowering stem from the parent plant.
  2. Use clean, sharp scissors or pruning shears to cut the stem just below a node.
  3. Remove any lower leaves to expose the nodes where roots will form.
  4. Dip the cut end of the stem in the rooting hormone.
  5. Plant the cutting in a container filled with moist potting mix or perlite.
  6. Place the container in a warm, humid environment with indirect sunlight.
  7. Keep the soil consistently moist and mist the cutting regularly to maintain humidity.
  8. Roots should develop within a few weeks, at which point the cutting can be transplanted into a larger container or garden bed.
  1. Choose high-quality Aji Dulce pepper seeds from mature plants.
  2. Fill seed-starting trays or containers with a sterile, well-draining seed-starting mix.
  3. Moisten the seed starting mix thoroughly before sowing the seeds.
  4. Sow the Aji Dulce pepper seeds evenly across the surface of the soil, pressing them gently into the soil but not burying them too deeply.
  5. Water the seeded trays gently using a fine mist or spray bottle to avoid disturbing the seeds.
  6. Keep the soil evenly moist but not waterlogged throughout the germination process.
  7. Place the trays in a warm, well-lit location with temperatures consistently between 70°F to 85°F (21°C to 29°C) to encourage rapid germination.
  8. Once the Aji Dulce pepper seedlings have developed several sets of true leaves and are sturdy enough to handle, transplant them into individual pots or containers filled with nutrient-rich potting mix.
  9. Plant the seedlings at the same depth as they were in the seed trays and water them thoroughly to help settle the soil around the roots.
  10. Place the seedlings outdoors in a sheltered, shaded location for a few hours each day, gradually increasing the exposure to sunlight and wind over a week.
  11. This process helps strengthen the seedlings’ stems and prepare them for the rigours of outdoor growing.
