Do you want to grow crown imperial seeds in Washington, but don’t know when to start them?
Starting crown imperial seeds is not as easy as it seems.
Here’s why:
- Crown Imperial 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 Washington’s growing season is not long enough, crown imperial 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 crown imperial seeds indoors in Washington:
