Do you want to grow holly seeds in New Hampshire, but don’t know when to start them?
Starting holly seeds is not as easy as it seems.
Here’s why:
- Holly 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 New Hampshire’s growing season is not long enough, holly 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 holly seeds indoors in New Hampshire:

When to Start Holly Seeds Indoors
Depending on the type of holly, it takes roughly 730-1095 days (2 to 3 years) to grow holly from seed indoors before you can transplant them into your garden. And it could take 3 to 5 years for your holly to bloom!
The approximate date of when you should start your holly seeds indoors can be found by:
- Finding the first average frost date HERE
- And then subtract 730 days from it
You can also find the average first frost date for most major cities in the below chart that I have created:
To help ensure the greatest success of your holly 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 holly 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 holly plants into your garden until 2 weeks after your first frost or else your plant will potentially die or not bloom
