Seedling rescue

So I just dug up two seedlings from a public garden (with permission from the attendent) on my lunch break. They are 12" and 18" high and now they're in a plastic shopping bag with dirt and wet paper towels.

I got at least a few inches of roots for both of them, but now I'm wordering if I need to do anything special when I get home beyond potting them up in a mix of potting soil and mulched wood? Strip leaves? Cut back? Light candles?

Congrats! Do you know what they might be from?

I would just pot them up and wait. Don't strip the leaves. They will need them. If they're only 12/18 inches high I wouldn't think they'd need to be cut down either. If they're seedlings they probably didn't have huge root balls yet anyway.

Thanks Seil! Not root balls as such, but tap roots, one going straight down through some tough clay and the other was wrapped around a sprinkler head.

I'm writing to the landscape architect to ask what the roses are! One of them is a beautifully fragrant white floribunda/polyantha but the rest are hybrid teas. Is 'Peace' sterile?

RE: Seedling rescue

Peace isn't sterile at all, but your description makes them sound more like Dr. Huey suckers. Seedlings wouldn't have the long, strong tap root, but more of a root "system" to be 18" tall. Suckers from under ground Huey roots would appear precisely as you describe them. Kim

Kim- If that's the case then next year I'll do some grafting! My Dad did rose and fruit tree grafting as a summer job back in the 60s so he could show me how.

RE: Seedling rescue

They would be good to use to learn on, however, they're very likely virused so you don't want to bud or graft anything of any real value to you for fear of infecting them through grafting. If there are roses in your garden you know are infected and you don't care about, they would be good to use to learn with. But, for things you really care about, new seedlings, or varieties you may have access to you know have been certified free from virus, please don't put them on these or they will likely no longer be free from infection. Once you learn and if you want to bud or graft more, there are sources for indexed (certified tested and not showing any infection) stock to use for those purposes. Kim

Kim- I've got them in pots away from my other roses- I thought I was being paranoid but I guess that wasn't such a bad instinct! I'm going to see how they do for a year or so before I even think of doing anything. Mostly that was an attempt at silver lining. I was really hoping I had something interesting!

RE: Seedling rescue

You really don't have to worry about them contaminating your other roses. We really don't have to be paranoid about that, honest! Kim

Why would the seedling have a virus?

It isn't a "seedling" it's a runner which is a new shoot that comes up from old root stock left in the ground. That root stock is probably DR. Huey and as far as is known all of the Dr. Huey root stock that was used for grafting had RMV. So any resulting runners that come up will also be infected.

A "seedling" is a plant grown from the seeds that develop inside the rose hip after it has been pollinated. It does not come up from roots in the ground. I don't know for certain but I do not think that seeds from an infected plant will also be infected but I may be wrong on that and if so hope others will correct me.

ah ha :) thanks Seil

Conerning contaminating other roses by above ground spread, the following link gives a description of an aphid spread rose virus found especially (so far) in California.

The following is what I have summarized for northern gardeners and PNRSV, a very common rose virus in the U.S.:

Underground root to root transfer has been shown to also transfer rose virus.

The following link gives the information that I have found concerning infected Blackberry chlorotic ringspot virus (BCRV) rose seedlings.
