Do you want to grow uva ursi in Pennsylvania, but don’t know when to plant them?
Planting uva ursi is not as easy as it seems.
- Uva Ursi 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 uva ursi won’t produce a bloom.
Today, I’m going to teach you the ideal time to plant uva ursi in Pennsylvania:

When to Plant Uva Ursi in Pennsylvania
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 uva ursi outside in Pennsylvania!
For your reference, I have created this table for average frost dates for most major cities in Pennsylvania. If your city is not listed below you can find its Last & First Frost Dates HERE.
Pennsylvania 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 uva ursi planted outside in Pennsylvania 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 uva ursi?
When you know a frost is coming you need to take action.
- If uva ursi are in pots, bring them inside
- If uva ursi are in the ground, cover them in burlap and hope they survive
Also, make sure not to plant your uva ursi in your garden too late.
- Planting uva ursi too late will cause small blooms or even worse, no blooms.
When Should You Start Your Uva Ursi Seeds Indoors?
Depending on the type of uva ursi, it takes roughly 730 days (2 years) to grow uva ursi from seed indoors and then transplant them to your garden. And then another 3 to 4 years to bloom!
For a specific date that you should start uva ursi seeds indoors you should:
- Find the last average frost date HERE
- And then subtract 730 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 uva ursi 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 “harden” your uva ursi plant, increasing its chances of fighting off diseases, insects, droughts, and wet conditions.
