Optimize Spacing and Airflow

Crowded jalapeño rows can harbor fungal diseases and stifle growth. Follow spacing guidelines—about 18–24 inches between plants—to allow air circulation and easy access for harvesting. Open canopies also make it simpler to spot caterpillars or aphid colonies before they become problems.
With ample airflow, you’ll notice fewer mildew outbreaks and more ladybird beetles settling in. These colorful predators often nest in lower foliage, hunting unsuspecting pests and ensuring your blooms turn into fruit rather than leaf-eating havoc.
