I'm setting up a window box and I got everything ready, but the plants I got all require that I wait until there is no more frost in order to sow the seeds. Or if I want to start now, I should start sowing indoors.
I live in New York, and the last frost date is around mid-april. What do you recommend? Should I wait until mid-april (seems like a long time), start indoors, or just start sowing seeds in the window box outside right now?
In case you can't tell, I am a complete newbie.
