Here is the BEST Time to Start Sweet Pea Seeds in Maryland (2023 Guide)

Do you want to grow sweet pea seeds in Maryland, but don’t know when to start them?

Starting sweet pea seeds is not as easy as it seems.

Here’s why:

  • Sweet Pea Seeds must be consistently watered, receive at least 8 hours of sunlight a day, & be kept at room temperature of at least 70 degrees Fahrenheit.

So if you don’t consistently water them they won’t germinate. If they aren’t in a room that is at least 70 degrees Fahrenheit they won’t sprout. And if it receives 8 hours of sunlight the plant itself won’t grow.

  • Because Maryland’s growing season is not long enough, sweet pea seeds cannot be sowed outside and should only be started indoors.

Because of this, I’m going to teach you the ideal time to start sweet pea seeds indoors in Maryland:

When to Start Sweet Pea Seeds Indoors

Depending on the type of sweet pea, it takes roughly 10 to 28 days to grow sweet pea from seed indoors before you can transplant them into your garden. And it could take 50 days for your sweet pea to bloom!

The approximate date of when you should start your sweet pea seeds indoors can be found by:

  • Finding the last average frost date HERE
  • And then subtract 10 days from it

You can also find the average last frost date for most major cities in the below chart that I have created:

Maryland Frost Dates

To help ensure the greatest success of your sweet pea seeds germinating you should:

  • Use a heat mat to ensure the gardening pot remains at 70 degrees Fahrenheit
  • Use a grow light to control how much light your sweet pea seeds receive
  • Water your seeds with a spray bottle to ensure your seeds are not overwatered

It should also be noted that you will not want to introduce your sweet pea plants into your garden until 2 weeks after your last frost or else your plant will potentially die or not bloom
