Welcome! Roses will usually continue to bloom until it gets too cold for them to or they don't get enough sunlight to produce any more buds. That's dormancy. Pruning is usually done right before the roses begin to grow again, usually late winter/very early spring. Depending on your area, you probably can prune anytime between now and late February. I couldn't find anything on gardening zones in Iran, but if your roses are blooming now, I would guess that you are in an area where roses don't really go dormant. In that case you can prune now (and take all the blooms inside as the previous poster suggested). If you don't prune, your roses can get tall and lanky and only bloom on the top.

No....that's not what I mean....you have to choose the branches that are behind the growing tip and nurture that and remove the growing tip to a spot that doesn't promote twiggy growth. Look on the link below under heading back. Linda C Here is a link that might be useful: Lesson on pruning

Thanks a bunch!! They are in a spot that gets sun just about all day so I think they get plenty of sun. They are a pretty shaped plant just not real full plus the blooms stay towards the middle of the plant. Gorgeous when it blooms though and its blooming some right now. Thanks again. Judy

do you have a pic of your wisteria in bloom and in late summer? Looks like Amethyst Falls can grow here in IL since it grows in your area. :)
