Do you want to grow borage in Missouri, but don’t know when to plant them?
Planting borage is not as easy as it seems.
- Borage 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 borage 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 borage in Missouri:

When to Plant Borage in Missouri
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 borage outside in Missouri!
For your reference, I have created this table for average frost dates for most major cities in Missouri. If your city is not listed below you can find its Last & First Frost Dates HERE.
Missouri Last & First Frost Dates
Unfortunately, Mother Nature plays cruel tricks on us every year.
It should be noted that the above dates are just averages.
There are years when the last frost comes MUCH later. Sometimes, the last frost happens much earlier and you can get your borage planted outside in Missouri 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 borage?
When you know a frost is coming you need to take action.
- If borage are in pots, bring them inside
- If borage are in the ground, cover them in burlap and hope they survive
Also, make sure not to plant your borage in your garden too late.
- Planting borage too late will cause small borage or even worse, no borage.
When Should You Start Your Borage Seeds Indoors?
Depending on the type of borage, it takes roughly 20-25 days to grow borage from seed indoors and then transplant them to your garden.
For a specific date that you should start borage seeds indoors you should:
- Find the last average frost date HERE
- And then subtract 25 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 borage 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 borage plant, increasing its chances of fighting off diseases, insects, droughts, and wet conditions.
