What’s a Hardiness Zone Map?
Easy peasy, right?
Truth or Lie? A Hardiness Zone May Contain Hotter or Colder Areas Within It
Higher and lower temperatures in a zone
Large bodies of water can change the zone
Microclimates in your garden
A microclimate is an area with fine-scale climate variations, like a warmer pocket caused by nearby blacktop and concrete, or a cooler spot in a hill or valley. An entire yard can be slightly warmer or cooler than the surrounding area because it is sheltered or enclosed. Microclimates can also differ from the surrounding area in terms of light exposure, moisture levels, wind, and soil.
When determining microclimates in your garden, look for areas that are slightly different than the surrounding landscape. Cold air pools in depressions, making low-lying areas of a yard colder than level areas. Areas next to houses or other buildings tend to be slightly warmer, as the structures absorb heat during the day and radiate it back out at night. Walls, driveways, and patios also absorb heat, making the spaces near them slightly warmer.
Truth or Lie? It’s OK to Ignore Hardiness Zones
Treat as annuals
Grow out-of-zone plants in containers
Newer cultivars for other hardiness zones
Do you know that National Garden Bureau members include the very best plant breeders and growers, who develop a wide range of cultivars that can push zones for traditionally grown plants? Newer cultivars may be bred for better cold or heat tolerance, allowing you to grow plants in your zone that previously weren’t an option due to extreme cold or heat. Thank goodness for our brilliant members!
