Seeds to Sow: Mid-March

 

20160315AnglaisThe choice of seeds to sow indoors explodes in mid-March! This really is the time to start so many seeds… but not all of them. Note that several popular plants are still missing from the list: tomatoes, marigolds, cucumbers, etc. Why? It’s still too early! The golden rule of seed starting is that you can be a bit late, as plants tend to catch up when planted outdoors, but you should never, ever start them too early! You want your seedlings to young and full of pep when you plant them out, not old, weak and stretching for the light.
