@AMKuska, I CANNOT figure out HOW I have kept 15 sweet bell peppers, that I originally planted last MAY (2021) alive, but they are slowly growing on top of a heat mat and heat a gro light with a clear cover for humidity, in my 53 degree F basement. 3 have even flowered.
ALL I KNOW from my recent studies is that ALL seeds want good heat to sprout, then good light, even the cool weather crops. I have been studying up on starting a Fall garden. I Almost got it in last year, but I got too busy and I am sorry that I didn't try late since our Fall stayed pretty warm here.
Local (U of Illinois extension) had a webinar last year on growing in the Fall and most crops (here) MUST be started in August. As You know we can get our hottest weather then, but the host said that they need that heat to start. She also said that you can harvest many after a freeze, and that they will be sweeter after being frosted.
I have heard over and over again that Brussels Sprouts are bitter when grown/harvested in the Spring, so why bother?
I planted the entire package of sweet bell peppers that I had bought in January, 2021 from High Mowing. None sprouted. The ones growing downstairs now were from a cheap package that I had.
I attribute the failure from my lack of expertise bc High Mowing had a good reputation.
It's all a learning curve and you NEVER KNOW if you will be successful, so trying something new is a good experiment, especially when it works.
