When I move stuff out or in - they never go back. In the Fall, I always wait til the absolute last minute. This year, I used 6 frost blankets over stuff on my deck and screen porch 3 times. And bringing stuff in is when I panic - so much stuff - so little space. Every freaking room - some filled.
The seeds I start inside are most all grown in 72 cell trays and stay there til April or May. I do not transplant anything inside.
I too grow a lot of stuff that is donated to my Master Gardeners group and sold at our late April Plant Sale. Everything we sell other than cannas and elephant ears are grown from seed. This year we sold nearly 3,000 plants and had our best sale ever.
In many ways Zone 5 sucks Dee - particularly from Nov - Mar. I am kept busy watering and trying to keep things alive for 5 or 5 months inside. But come Late Dec - Mar I am a seed planting maniac. :thumbsup.
Thinking of trying Welwitschia mirabilis again. Last year I totally failed with 12 seeds. The challenge is getting the plant more than ~ 3 inches tall before they die.
I like growing weird stuff and challenges.
