Here is the BEST Time to Plant Olearia in Massachusetts (2023 Guide)

Do you want to grow Olearia in Massachusetts, but don’t know when to plant them?

Planting olearia is not as easy as it seems.

Here’s why:

  • Olearia 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 olearia won’t produce a bloom.

Today, I’m going to teach you the ideal time to plant Olearia in Massachusetts:

When to Plant Olearia in Massachusetts

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 olearia outside in Massachusetts!

For your reference, I have created this table for average frost dates for most major cities in Massachusetts. If your city is not listed below you can find its Last & First Frost Dates HERE.

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 olearia planted outside in Massachusetts 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 olearia?

When you know a frost is coming you need to take action.

  • If olearia are in pots, bring them inside
  • If olearia are in the ground, cover them in burlap and hope they survive

Also, make sure not to plant your olearia in your garden too late.

  • Planting olearia too late will cause small blooms or even worse, no blooms.


When Should You Start Your Olearia Seeds Indoors?

Depending on the type of olearia, it takes roughly 95 days to grow olearia from seed indoors and then transplant them to your garden. And then another 9 to 12 months to bloom!

For a specific date that you should start olearia seeds indoors you should:

  • Find the last average frost date HERE
  • And then subtract 95 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 olearia 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 olearia plant, increasing its chances of fighting off diseases, insects, droughts, and wet conditions.
