I covered them with a tarp I guess I needed more...Do i need to dig the tubers out ? Or just cut the frozen dead part off and put them in a warmer place?
Leave them be. Just tent cover with weighed down newspapers and they will be fine.
Do the same with any annuals you've already set out.
I cut off the frozen shoots,and from what I researched they may come back !!! I Will Never think that by putting a tarp on them will save them again. They are indoors till all threat of frost has passed in the containers
Have a great week !!!
They usually recover from frosts with good enough frost covers (a simple tent or a plastic dome helps). In anycase, it's not the stems that you should be concerned with but it's corms which should be protected with mulch.
I have had mine out for over 3 weeks now with no problem. digging them out after they've started to produce roots interrupts their progress. In anycase, I'm sure your dahlias will recover.
Hi! I planted my dahlias out early, too and (thankfully) covered them with light "tupperware" containers. They usually do a great job in fall even after a few hard frosts in my garden here, so I'm sure yours will recover as long as the corms weren't killed. Hope it works out!
