Here is the BEST Time to Start Butterfly Bush Seeds in Delaware (2022 Guide)

Do you want to grow butterfly bush seeds in Delaware, but don’t know when to start them?

Starting butterfly bush seeds is not as easy as it seems.

Here’s why:

  • Butterfly Bush 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 Delaware’s growing season is not long enough, butterfly bush 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 butterfly bush seeds indoors in Delaware:

When to Start Butterfly Bush Seeds Indoors

Depending on the type of butterfly bush, it takes roughly 7 to 21 days to grow butterfly bush from seed indoors before you can transplant them into your garden. And it could take 1 year for your butterfly bush to bloom!

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

  • Finding the last average frost date HERE

To help ensure the greatest success of your butterfly bush 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 butterfly bush 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 butterfly bush plants into your garden until 2 weeks after your last frost or else your plant will potentially die or not bloom
