Do you want to grow mandevilla seeds in Massachusetts, but don’t know when to start them?
Starting mandevilla seeds is not as easy as it seems.
- Mandevilla 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 Massachusetts growing season is not long enough, mandevilla 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 mandevilla seeds indoors in Massachusetts:

When to Start Mandevilla Seeds Indoors
Depending on the type of mandevilla, it takes roughly 30 days (1 month) to grow mandevilla from seed indoors before you can transplant them into your garden. And it could take 1 year for your mandevilla to bloom!
The approximate date of when you should start your mandevilla seeds indoors can be found by:
- Finding the last average frost date HERE
- And then subtract 30 days from it
You can also find the average last frost date for most major cities in the below chart that I have created:
To help ensure the greatest success of your mandevilla 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 mandevilla 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 mandevilla plants into your garden until 2 weeks after your last frost or else your plant will potentially die or not bloom
