A simple 2x4 frame with polycarbonate panels on the sides.
My growing season is short and plagued with cool springs so I’d like to give them a head start before my last frost date!

Dear windy...
Save your money and time.
Basjoos spring growth is determined by ground temps.
Not air temps.
The plant is growing under the surface and spreading once the soil is 40+-
A structure will not give you an advantage..
But..... you may fertilize now with a granular 12-12-12 through 19-19-19 for the springtime boost.
Use what you can afford for fertilizer....the plant is not picky.
Has anyone ever winterized with one of these?
