Creating a thriving chiltepin garden in outdoor plant boxes requires careful selection of companion plants and optimal growing conditions. Chiltepin peppers, known for their intense heat and compact growth, flourish when paired with plants that enhance their environment. Here are the best plants to include in your chiltepin garden:

1. Basil: This aromatic herb repels pests like aphids and spider mites, which can harm chiltepin plants. Its shallow roots also complement the pepper’s growth.

2. Marigolds: These vibrant flowers deter nematodes and other soil-borne pests, creating a healthier environment for chiltepins.

3. Oregano: A low-maintenance herb that thrives alongside chiltepins, oregano improves soil quality and attracts beneficial insects.

4. Garlic: Planting garlic near chiltepins can help repel pests while adding a flavorful companion for culinary use.

5. Cilantro: This fast-growing herb provides shade for chiltepin roots and attracts pollinators to boost pepper production.

For optimal results, ensure your outdoor plant boxes receive full sunlight (6-8 hours daily) and well-draining soil. Water chiltepins moderately, allowing the soil to dry slightly between waterings. With the right companions and care, your chiltepin garden will yield a bountiful harvest of spicy peppers. Happy gardening!
