Sun Requirements

• NM 64 thrives in full sun, needing 6–10 hours daily.
• Texas heat intensifies flavor and helps pods develop that signature NM chile aroma.
• Mulch around the base to keep roots cool and reduce moisture loss.
• Container plants can be moved to light afternoon shade during extreme heat waves.

Watering

• Water deeply 1–2× weekly, depending on rainfall.
• Let the top 2 inches of soil dry before watering again.
• Avoid overwatering — it can cause blossom drop and root issues.
• Mulch helps maintain moisture and stabilize soil temperature.

Soil & Fertilizer (Organic‑Only)

Use a well‑draining mix: compost + native soil + coarse sand or perlite.

• Feed weekly with compost tea or fish emulsion, alternative
• Feed monthly with worm castings

Avoid heavy nitrogen — it encourages leaves over fruit.

Organic Pest Control

Watch for:

• aphids
• hornworms
• leaf‑footed bugs
• spider mites in dry heat

Treat with neem oil or insecticidal soap at dusk.
Hand‑pick hornworms (they’re harmless but hungry).
Encourage ladybugs and lacewings.
Avoid chemical pesticides — they harm pollinators and soil microbes.

Container vs In‑Ground Care

Container:  

• Use a 3‑gal pot minimum; 5‑gal produces the best yields.
• Ensure drainage holes.
• Terracotta helps prevent soggy roots.

In‑Ground:  

• Plant in raised beds or loosened soil enriched with compost.
• Austin clay needs amendment to drain properly.
• Stake plants if they get top‑heavy with fruit.

Harvest Instructions

• Harvest when pods turn deep red, glossy, and firm.
• Green NM 64 pods are excellent for roasting and have a milder heat.
• Cut peppers with scissors or pruners to avoid damaging stems.
• Regular harvesting encourages more fruit production.

Drying & Storage

NM 64 dries beautifully.
Options:

• air‑dry whole pods in a shaded, ventilated area
• roast and freeze for later use
• dehydrate slices for powder

Store dried chiles in airtight glass jars away from sunlight.
Properly dried NM 64 pods keep flavor for 6–12 months.
