How Irwin Compares to Other Areas
In ZIP 95194 in San Jose, California (CA), zone 10a means winter lows stay above 30 F. Tree selection there focuses on drought tolerance because summers are dry. The practical difference is that you need trees that handle cold winters, not dry summers. Your zone 6b requires cold-hardy choices instead of drought-tolerant ones from warmer zones.
ZIP 36853 in Dadeville, Alabama (AL) sits in zone 8a with winter lows of 10 to 15 F. The growing season is long and humid. Here, the zone usually pushes the choice toward heat-tolerant and disease-resistant varieties. For you, humidity is less intense, but your cold winters limit what survives. Species that thrive in Alabama may not handle your zone 6b winters.
ZIP 72451 in Paragould, Arkansas (AR) is also zone 8a with lows of 10 to 15 F. Their winters are milder than yours. Locally, that points buyers toward trees that can handle colder snaps, like the Chinkapin Oak or Thuja Green Giant. The takeaway: what works in warmer zones may not survive your -5 to 0 F lows. For Irwin buyers, the key is selecting trees that withstand your colder zone. The featured trees are all zone-matched to 6b.
