Do you want to grow Catnip in Hardiness Zone 3, but don’t know when to plant them?
Planting Catnip is not as easy as it seems.
Here’s why:
- Catnip are not able to survive frost or cold weather under 50 degrees Fahrenheit.
So if you plant them outside too early in the spring they will die. And if you plant them too late, your Catnip won’t produce a harvest before the first frost arrives in the fall.
Today, I’m going to teach you the ideal time to plant Catnip in Hardiness Zone 3.

When to Plant Catnip in Hardiness Zone 3
As you may have already guessed, you need to pay very close attention to your local weather in the spring. Specifically, you are going to need to watch when the last frost occurs.
In general, when there hasn’t been a frost for two weeks, you are SAFE to plant your Catnip outside in Hardiness Zone 3!
Unfortunately, Mother Nature plays cruel tricks on us every year.
There are years when the last frost comes MUCH later. Sometimes, the last frost happens much earlier and you can get your Catnip planted outside in Hardiness Zone 3 much quicker.
Like I said before, you need to be very diligent in checking your local weather.
So what happens if a frost comes AFTER you plant your Catnip?
When you know a frost is coming you need to take action.
- If Catnip are in pots, bring them inside
- If Catnip are in the ground, cover them in burlap and hope they survive
Also, make sure not to plant your Catnip in your garden too late.
- Planting Catnip too late will cause small Catnip or even worse, no Catnip.
When Should You Start Your Catnip Seeds Indoors?
Depending on the type of Catnip, it takes roughly 40-50 days to grow Catnip from seed indoors and then transplant them to your garden.
For a specific date that you should start Catnip seeds indoors you should:
- Find the last average frost date HERE
- And then subtract 50 days from it
Not only this, but I recommend again paying close attention to your local weather report.
It should also be noted that the best technique for bringing your Catnip plants outside is to introduce them (in their pots) outside for an hour. And then increase the amount of time they spend outside each day by an hour until they have been outside for 8 hours.
This will “hardened” your Catnip plant, increasing its chances of fighting off diseases, insects, droughts, and wet conditions.
