Lost almost all my heucheras last winter. Actually, the last two winters have killed them all off. At one time, I must have had 20 plants. Now I have maybe four and it's iffy as to whether they will survive even now. They look terrible! Crying

It was a bad Winter and many died down, but most are starting to show some signs of life this week. Will most likely be another week before I know which ones will not come back.

I was out spreading compost and lo and behold a heuchera came back! I lost at least four over the winter, and two the winter before. I blame my dogs tromping on them throughout the winter. I'd given up on it. Maybe it was going to come back anyway, but I like to think the compost I put over it a few weeks ago gave it the boost it needed. Of course, it's only one leaf....but that's a start. Lost another one in a different garden. Right between two other varieties. Not sure what happened.

Two of mine, the first two that I ever bought, did actually survive. They actually are looking quite nice now. I also had four in hanging baskets that I forgot about that over wintered in the garage. They are looking okay now as well.

My dog trampled my new heuchera. I'm ready to put sharpened stakes in that garden so the damn dog stays out! I did block it off a bit, but my lab has NO social graces at all. Just dum de dum through everything. I should have spent the money on that neat push in fence piece I saw.

I have a dog that does the same thing. He's oblivious about what he tramples down. We are using those small fences now and it does help.

I have small fences. Did nothing. I think they have to be at nose level for him to see them.

I did end up losing 5 or 6 plants but I guess that is not too bad considering how many I have and how bad of a Winter we had. I have been lucky with the dogs I have had over the years . I have always been able to train them to keep out of the gardens. The one I have now does have a spot in the back of one of the gardens he likes to lay down in on hot days behind a shrub but always enters from the side and leaves the plants in front alone.

My garden is probably six feet from the door. And the only thing he has on his mind is any squirrels and how bad he has to go. Making a 90 out the door will never happen without a tall fence. My mistake, I guess. I've always had dogs. LOL

I did not have any deaths. I am still using my pot system and I am very happy. I love these plants so much I as happy to try to find a way of not buying them as annuals.

I lost only two: Dolce Cinnamon Curls and Black Beauty, both added in 2017.
Now I have 14 Heuchera cultivars left.

Skits, in the past, I have done nothing special to protect them. We get about a foot of snow each winter and the temps get to the mid -30's C (-30c is -22f) for at least a few weeks each winter. We often have seven months of snow. In these conditions, my heucheras have been doing fine. What they don't like is when we get too much fluctuations in temperature, warming up and then freezing again, then warming up and freezing again. We got a lot of that last year.

We used to have snow for at least six months. The last few years we've been bare until spring. Not good for anything. Times are changing. I think I'll stick to the ground. I fortunately have enough leaves to cover so I don't usually get any heaving. Just the dogs (sigh).
