Mine did not. I had a lot of new planted plants that did not make it though. Nothing I had in plastic containers made it through last winter. I think the snow acts as an insulator in grow bags because most of my stuff in grow bags lived. I had an Apple die that was already in decline and a black gold cherry did not make it but it was sending out more suckers than growth. I had a Comice pear and sweetheart apricot not make it in a grow bag too but those were also in decline. Simply put everything that did not make it through our harsh last winter was either in decline already or in plastic pots which I just donāt think had enough heating power
Sorry to hear that. Good that you have pieced together why they didnāt survive. It was a weird spring too which probably didnāt help matters!
