New Planting Map Reflects Warmer Winters

NH Plant Hardiness Map

The USDA recently released a new growing zone map for the entire country. The Plant Hardiness Zone Map is the guide gardeners use to determine what plants and flowers will most likely thrive in their location. This is the first significant update in more than 20 years. The new online interactive maptakes advantage of much more detailed data analysis, and it’s making news because it shows that warmer winters are sustaining plants that previously would have died off in colder climates.

Cathy Neal is a specialist in nursery and landscape horticulture with the UNH Cooperative Extension. She says the new map hasn’t changed all that much for New Hampshire- but it does offer a few surprises- and much more detail.

For many radio listeners throughout New Hampshire, Rick Ganley is the first voice they hear each weekday morning, bringing them up to speed on news developments overnight and starting their day off with the latest information.
