Important dahlia question.

Hello all,

I had never tried dahlias and a friend of mine last year gave me 50 dahlias. I planted them all, and they were beautiful all season. I was told since my zone is 7A I was suppose to take them up but was too busy with work to do so. I didn't even mulch them. I have been preparing my beds for the season and have noticed quite a few are coming up. The beginning of winter was warm, but the end was very cold. Am I just lucky, or should I have heavy mulched them. Any advice for this year.

You may have been lucky! The key question is: Does the ground freeze in the winter where I live? If it is an unqualified yes then you are lucky and in a hard winter you may have lost quite a few. If the ground doesn't freeze then just mulch them with 4-6" of something like leaves or pine straw. I talked to a fellow one time that lived in Central Ohio and didn't dig his dahlias but he mulched them with a couple of feet of leaves. So they can stay in the ground if you do it right to prevent them from freezing.

Storing dahlias inside can cause dahlias to shrivel or rot if you don't use proper techniques so you must select one where you can be successful. Check out the Dahlia Society of Georgia web site menu item Dahlias That Grow Well in the South which discusses one and gives a website for another.

Well, it is probably a combination. I'm zone 6 & the last 3 years I have overlooked a few dahlias when digging in the fall, & "knock on wood" :) those have come back. They didn't get mulched, since I didn't intentionally leave them. We occasionally get a winter with temps below 0, but haven't the last few years. We do get below 10 a very few nights though, & still I see them come back. The ones I dig though do better, but that may be because I just left a piece of one. This fall I may just mulch really well & leave them in the ground.
