Siberian C as Rootstock and Fruit


I guess I’m not sure why you are hunting the most winter hardy rootstock for NJ/Washington DC?

Either way, I don’t have any experience with Siberian C. I do have some experience with K1, and tend not to like it for a peach rootstock.

I have one Harrow Diamond peach on K1 which is surrounded by other Harrow Diamonds on seedling. The K1 is not nearly as productive overall and suffers more bud kill in the winter. On the plus side, not much pruning is required, the fruit tends to run a little bigger and sweeter, but that may have something to do with less fruit on the tree.

Well after I discovered that Nemaguard was not hardy and the krymsy 1 problems you mentioned and the fact it did not grow much. When I read it tended to produce a semi-dwarf and found a source on ebay I though why the hell not. I planned to gorilla garden the extras anyhow

Also my soil in NJ is fine but in DC its heavy clay.


what was your seed source? mine came from Wisconsin also. After the leaves fully mature maybe we can compare pictures for similarities and differences.

I bought mine as a whip from Rolling River Nursery, I believe, in 2015. The foot tall sprout is smaller than the whip I started out with four years ago, but I leave it be as long as it is hanging in there.

The Ebay vendor was 20 seeds for $10. next time there available you might want to try those.

After I put a couple of these in the ground im going to have to find a home for the rest.

My Siberian-C has had the top freeze and it resprouted several times. It is still only about a foot tall. I leave it be in its hardware cloth cylinder, but not much hope for it amounting to much, unless the climate changes a lot.

Any updates on Siberian C? I’m interested in these for fruit as they are said to be much more disease and pest resistant compared to other types of peaches and I don’t spray. I just purchased 2 trees yesterday.

Still only a foot tall in Sept of ‘22. I don’t have much hope for it.

You could always bend it to the ground and mulch over it for extra protection

Mine just arrived! Excited for what the future holds for my Siberian Cs!


if your Siberian is that tender for you, the contender i put in from fedco this spring isnt probably going to do any better here. fingers crossed.

I should get mine tomorrow.

Here is an old review from houzz from a grower in Alberta.

They die to the snowline every year, even in an el nino year. They are terrible to eat peaches

Another from MN - Not good for eating raw.

Then there is this technique. from the guy who did the review i think.

There is another peach called Bailey Hardy from Univ of Minnesota that claims -30F but not much info on the net.


thats the same guy that showed me how to over winter my figs here. great idea. i also found a Russian vid. that showed the same technique. if my contender dies to the snow line this winter that is what im going to do for the following winter…

My Contender has survived -32 here with a little dieback. Unfortunately no fruit yet though.

thats good news! how old is it? from what ive read the younger the tree the more chance for damage. mines a 6ft. 1.5in caliper.

It’s about 4 years old now, I got it as a bare root whip. I had a young Veteran that was supposed to be hardier, but that one froze to the snow line.

seems like all the peaches rated to z4 arent really so. maybe just market hype but some of the nurseries that usually are conservative on zone estimates are also saying z4. time will tell. mines in a spot protected from the N.W wind so hopefully it makes it.

I’ve tried planting a number of peach trees over the years, but they all winter-killed the first winter. Plant something else!

Well, actually the Siberian-c keeps resprouting, so is still alive.
