Q: I have a front yard flower bed. Can I successfully plant petunias by broadcasting the seed there? When is the best time to do it?
A: Petunias can certainly be grown from seed but it’s usually done indoors or in a greenhouse.
But if petunia seed are planted in the spring when the ground is finally warm it takes several weeks to get flowers, possible mid-June. By contrast, you can buy flowering petunia plants at a nursery in late April.
