Growing Peppers in New Mexico
Peppers in New Mexico's Climate
Peppers thrive in subtropical heat year-round. Plant from August through February for cool-season production, or grow year-round if you can manage pest pressure. Hot peppers especially love your climate — habaneros and superhots that struggle in cold zones produce abundantly in zones 9-10. Your biggest challenge is pest management in warm, humid conditions, not temperature.
