I usually repot when they have two or three true leaves.

How exciting, Chris! I’m no help, but congratulations. It will be fun to see them bloom. Lisa

Congrats Chris !!! :)

I never done anything like that. They look beautiful..not bad from seeds. Great job :)

Congrats! I'd wait a month to pot them up.

Chris that is great!! I winter sowed mine. It was so easy. I had many seeds in clear plastic solo cups, so I transplanted them when they were tiny. You can wait a bit longer or go ahead and pot them up. The seedling are surprisingly tough. I was also quite shocked at the root system they had. It worked out well for me and I did not lose any. I am ashamed to say, that I just stuck my finger deep in the cups, next to a seedling and lifted up. (I had squeezed the cups some to loosen things up) You can leave the ones that are just sprouting, just gently work around them. I kinda had no choice. I put way to many seeds per cup (I didn't think they would sprout) so I had seedling that were almost tangled up.

It was my first year winter sowing and I love it. I think the huge bonus is that your plants are hardened off. I used to start some things under lights, but struggled with them while hardening off. (lost many)

Please post pictures when they bloom!! That's the best part!

I liked to wait till all seedlings had at least one true leaf, but I don’t think it would hurt if you repotted them now.

Wow! That is fantastic, Chris. Beautiful seedlings, and you chose such a great seed parent. Roses don't get any better than TS. No bias, of course. TS is just my all time favorite rose ever. You may have inspired me to hunt for hips in my TS hedge.

I've only raised pollinated rose seeds a few times, and I got nothing like your big batch of babies. The larger ones look like they can be potted up. I'd probably wait on the smaller ones. My thumbs are not as green as others on the forum, and if I give a seedling an excuse to croak, it will. :-)

Great advice and timing suggestions from those with experience. I've made a note to follow the "1 to 3 true leaf" cue. I love this forum! Carol

Thanks everyone! I potted up most of them but left the smaller ones to grow up a bit. I was surprised by how long some of the roots had already gotten. Too bad I’ll have to wait till next year for blooms. Luckily I also have some Sunny Knockout seedlings (at the complete opposite end of the rose spectrum) that I expect to bloom this year.

Oh, FUN!

@chris209:

As a PS, be aware that a percentage of 'Tuscany Superb' seedlings make flowers that have badly rolled petals resulting in malformed blooms. This is a genetic thing and not something the plant will outgrow. So don't be afraid to cull deformed/quill-bloomed plants as they appear. It is also quite likely that 1/3 to 1/2 of them won't flower until their third year.

Good luck! I know you will find a couple of keepers in the lot.

Thanks Paul. Something to look forward to!
