Seeds to Start in March – Zone 5A

Today I’m sharing which seeds to start in March. Whew!  As I promised in January and February, March is a HUGE month for starting seeds!

Pretty much all the seeds above can be started in April except for asparagus.  If you’re establishing a new asparagus patch and want to get a lot of plants going seeds are most definitely the way to go, but you need to do that this month if you’re in zone 5A.

How about you, are you starting anything new for your garden this year?

Personally, I’m planting a bunch more flowers this year so I can pretty up my front and save from buying annuals at the greenhouse.
