Hollyhock Plug Plants

When they can go out depends on where you live. If you are in upper Minnesota, it isn't time. In my zone 6a, established hollyhocks are starting to emerge. Before you put the plugs out, spend a week slowly acclimating them to outdoor temps, sun, wind and less frequent watering. https://www.burpee.com/gardenadvicecenter/areas-of-interest/seed-starting/hardening-off-your-seedlings/article10355.html
