Finding your zone/Which Zone are you in?
Zones are the specific temperature associated with your area. You can check your zone area by visiting the USDA Plant Hardiness Zone Map- By entering your Zip code, you can determine which zone your area comes under. These guidelines are designed to select plants suitable for its zone all year round.
Attributes of Zone 6
Zone 6 falls under the temperature range of -10º to 0º F. Hence, it is divided into two types with a 5º degree difference: Zone 6a and Zone 6b.
- Zone 6a: Temperature between -10º to -5º F.
- Zone 6b: Temperature between -5º to 0º F.
A variety of shrubs, flowers, fruits, and trees grow best in zone 6 with a medium-time frame. You can start planting seeds from March onwards and set the plants outside after observing the shoots.
Here are the 11 top shrubs that can provide shade in your garden.
