Welcome to GardenWeb, Mary!

I grow a lot of roses in pots. They do just fine so don't worry about that. I've had every thing from minis to climbers in pots and you just have to size the pot for the eventual mature size of the plant. But for the most part a standard size rose will be fine in about a 20 gallon pot. With most minis you can go a little smaller, 10 to 15 gallon pots.

You don't say where you are at the moment but I think that in almost any climate those tiny plugs would start out best in the 1 gallon pots. I've found that if I plant them right away into big pots they don't seem to do as well. They sort of just sit there growing roots to fill up the big space with not much top growth. And here that means they don't winter as well. Once they get to a bigger size in the gallon pots they do better in the bigger pots. Hope that helps!

Thank you Seil! I think I'll start them out in the one gallons until they get a bit larger. That's a good point about the roots growing instead of filling out on top in larger pots. I'm not too sure how big the actual plants are, but I'm sure they're pretty small. I feel much better about keeping them in pots. Thank you again!!! :)

Mary, if you move around a lot, then the start-small policy with pots is a very good ideafrom a practical standpoint. It's easier to graduate from pot size to pot size, season to season, as the roses mature in size and root system. Give a baby rose a giant container, and you'll have to lug all that unnecessary dirt around from place to place.

Like Seil (a REALLY good rosarian here - I always listen), I've grown all sorts of roses in pots. The only ones I've given huge "homes" to start with have been the climbing noisettes. All the others trade up in real estate as time passes, just like the humans who own them (or is the ownership thing the other way around?)
