When deciding what planting zone is New Mexico, remember that zones impact:
- Plant survival over winter
- Flowering and fruiting schedules
- Timing for planting and harvesting

This contrast shows why gardeners often ask what planting zone is New Mexico, as timing and plant varieties must match the local zone conditions.
