Here is the BEST Time to Transplant Petunias in Hardiness Zone 6 (2023 Guide)

Do you want to transplant petunia plant seedlings, but don’t know when the best time is to?

Transplanting petunia flowers is not as easy as it seems.

Here’s why:

  • New petunia plants must be consistently watered, receive at least 8 hours of sunlight a day, & be kept at a temperature of at least 70 degrees Fahrenheit both inside and in a garden.

So if you don’t consistently water them they will quickly wilt. If temperatures consistently fall below 70 degrees Fahrenheit they won’t grow and may even die. And if they don’t receive at least 8 hours of sunlight the plant itself won’t grow.

  • Because the Hardiness Zone 6 growing season is not long enough, you have to start your petunia plants indoors and then move them into a garden.

Because of this, I’m going to teach you the ideal time to transplant petunia seedlings:

When to Transplant Petunias

There are two different times you’ll need to transplant petunias plants.

First, you should transplant your petunias plants from a peat pot to a larger (5-gallon) gardening container once your petunias plants get between 3 – 4 inches tall. This will take approximately 6 to 8 weeks after you first plant your petunia seeds.

The second time you should transplant your petunia plant is when you move it from indoors to your outdoor garden. You should transplant your petunia plant into a traditional garden or raised garden 10 – 14 days after the average last frost.

To help ensure the greatest success of your petunia plant thriving you should:

  • Slowly acclimate your petunia plant to the outside environment. Move your petunia plant outside for one hour a day and increase this an hour every day until it can withstand mother nature for 8 straight hours.
  • After transplanting your petunia plant into your garden provide a thick covering of mulch to help it ward off cold, disease, and pests, and better retain water during the summer months.
  • Cover your petunia plants with burlap or a protective covering if you notice that a late frost may occur to protect them from wilting and dying.
