Northern Kentucky, just on the south side of the Ohio River, falls into planting zone 6b. Learn more about it in this article so you can choose the best plants for your area.
But if you want to know what are the planting zones for other Kentucky regions, check out our guides below:
What planting zone is Northern Kentucky?
The Northern Kentucky Area Development District (NKADD) is entirely in the USDA hardiness zone 6b, which means it experiences extreme minimum temperatures ranging from -5 F to 0 F. This makes it the coldest part of the state, which is otherwise mostly in zone 7a.
The NKADD comprises the following counties:
- Boone
- Kenton
- Campbell
- Carroll
- Gallatin
- Owen
- Grant
- Pendleton
This means that important cities like Covington, Florence, and Independence are all in zone 6b. Moreover, Cincinnati, just across the Ohio River, is also in zone 6b.
What planting zone is the Golden Triangle?
The Golden Triangle is the area comprising Lexington, Louisville, and Northern Kentucky, an important economic region in Kentucky, and where most of the population is located.
So, if you want to go a bit beyond Northern Kentucky to know which planting zones are in the Golden Triangle, here’s what you need to know:
- Louisville: The biggest city in Kentucky and home to Muhammad Ali is in zone 7a, and so is all of Jefferson County. This means its lowest temperatures range from 0 F to 5 F.
- Lexington: This city is located in zone 7a. Other parts of Fayette County, mostly in the north, near Kentucky Horse Park, are in zone 6b.
- Northern Kentucky: As we’ve seen, this region is in zone 6b. That includes important cities like Covington, Florence, Independence, and Newport.
Tip: Most of the counties situated north of I-64 are entirely in zone 6b, with a few exceptions that have small areas in zone 7a. Jefferson County, which is cut by I-64, as we mentioned, is entirely in zone 7a.
