PORTLAND, Maine (AP) — Maine Christmas tree growers are scrambling to meet demand during a compressed holiday season. At Richards Christmas Tree Farm in Mapleton, there has been no rest since the first trees were cut last month for wholesale orders, said Gaye Richards, who owns the 250-acre farm with her husband. Rick Dungey, a spokesman for the national group, said there should be plenty of supply to meet demand at big-box stores, smaller retail lots and choose-and-cut operations.
