Hi I'm looking for info on cold frame ideas for the zone 6b area in Franklin county in south Central Pennsylvania. Construction ideas how to set them up and where ( outside, inside unheated shed or using window wells on east north east side of house) should I heat them and with what ( heaters or heating mats). What temp should trees go into cold frame. I have a juniper, cotoneaster demi lowfast, Chinese elm, yellow jasmine and a goshiki Holly (false holly). They are all in smaller pots 6-7 inch pots I'm pretty sure they can all stay out but not sure about the false Holly or elm because see different info on these. Is there any gadgets that will not brake the bank but will make things odds better in tree surviving I lost some last winter with them just in unheated shed thanks
