Finding First and Last Frost Dates
First, you may be wondering what frost dates are and why they’re important.
A frost date is the average date of the last light freeze that occurs in Spring and the first light freeze that occurs in Fall.
Knowing your average frost dates for your zone is super important because it is what determines when you should plant all the plants in your garden.
To find your first and last frost dates check the Farmer’s Almanac Website. Just type in your zip code and it will give you the dates for your location.
Keep those dates handy and you’ll be able to easily plan out your planting schedule.
In fact, if you’d like to download the schedule that I use just click on the image above, fill in your email, and it will be sent right over!
It includes all of the exact times for when to plant transplants as well as when to direct seed for all of your most common vegetable plants.
Although, just know that frost dates are meant to be a guideline. There is a 30% chance that a frost may occur before or after the average first and last frost dates.
Types of Freezes:
- Light freeze: 29-32 degrees F. – Kills tender plants.
- Moderate freeze: 25-28 degrees F. – Destructive to most vegetation.
- Severe freeze: 24 degrees F. and below. – Most plants are severely damaged.
Finding Your Zone
If you know you live in zone 9b then all of the information in this article will be applied to you, but if you aren’t sure check out this plant hardiness zone map, type in your zip code and it will show right up!
What is a Plant Hardiness Zone
The plant hardiness zone map is a tool that will let you know if plants can tolerate year-round conditions in your area.
It is based on the area’s high and low temperatures as well as average amounts and distributions of rainfall.
The zones change by 10-degree Fahrenheit differences in average minimum temperatures. The zones are then broken down again into “a” and “b” zones, which have 5-degree Fahrenheit differences.
Zone 1 has the coldest climate and as climates get warmer the zone number increases up to 11.

Zone 9b Gardening – Frequently Asked Questions
When should I start seeds in zone 9b?
As a general rule, most vegetables should be started indoors 6-8 weeks before your last frost date. In zone 9b, this would be around January 1st – January 18th.

Zones change by 10-degree Fahrenheit differences in average minimum temperatures. The zones are then broken down again into “a” and “b” zones, which have 5-degree Fahrenheit differences.
So zone 9a has minimum temperatures of 20 – 25° Farhenheit and zone 9b has minimum winter temperatures of 25 – 30° degrees F.
What is hardiness zone 9b?
A hardiness zone is a geographic area with specific conditions relevant to plant growth and survival. It typically refers to the minimum temperatures that a plant can tolerate.
So a plant labeled zone 9b hardy would mean that variety can handle minimum temperatures of 25 – 30° F.
