For me to get started with the plants I want to set out at the end of
March . Last year and the year before I tried those peat disc things
(wet 'em and they expand into a little barrel shape) with absolutely
dismal results . This year I'm going to try something different , using
potting soil or starter mix .
I have a decent plastic tray but I need to divide it into compartments
. I
was considering shoebox-type cardboard , or maybe some plexiglass
strips . Or I could just go buy some small plastic cups and put holes in
the bottom for drainage .
How do y'all start your sets ? I'll be doing tomatoes , peppers ,
marigolds , and maybe some zucchini and cantalopes . I usually do the
stuff with bigger seeds directly to the ground ...

I use plastic pots, I have a million of them left over from plants that
I've bought at garden centers over the years.

Unless you have a greenhouse don't jump the gun, if you start the plants
too early they will just keel over and die on you. I make that mistake
over and over again. Especially when we have a severe winter I want to
start growing something so I start a bunch of plants in early March and
they always die on me long before I can plant them in the ground in late
May or early June. I'm not feeling the urge this year because we haven't
had a winter at all in New England. Aside from the storm in the fall that
wiped out our power for a week we haven't had a single snowflake and the
temperatures have been well above freezing.
