About Tomatillo
Tomatillo is a warm-season Solanaceae crop — fruiting in summer with shared pest and blight risks across the nightshade family. Companion choices matter for disease rotation, nitrogen, and trap crops.
Tomato psyllid and blight pressure rise in humid North Island summers — spacing and airflow help.
