Rooting cuttings is the easiest way to go. There are tons of methods to do that. You can do a search on here or do a google search and you'll find lots of information on doing rooted cuttings.

Oh and just because you see roots, don't get too excited and take the cutting out of the bag. Wait until you have good roots and start seeing new growth before taking your cutting out of your bag or greenhouse. Even then you need to acclimate the cutting slowly or it will wilt. Open the bag or lid a little at a time before taking completely out. Only repot the cutting when the roots fill the cup. You can plant outside the next spring but tender cuttings should be protected from freezing temperatures their first winter.

Another couple of things, best results come from burying half (3 inches) of the cutting in the medium. Also cuttings from a stem or cane that recently bloomed and the flower is spent or dried are said to work best. I am new at this too and am just relaying everything I have learned and can remember. I have been picking apart a nursery worker's brain. Bottom heating pads produce the best results as well if you want to get real technical and want to spend the money.

I use similar method. Rubbermaid container that holds about 40 cups with a piece of plexiglas for a lid. (bought the containers for $1 without lids at Goodwill). I use Miracle Grow potting soil. I am trying seed starter mix this time as someone on here said they use it. dampen it and let it sit, sometimes over night so it is not too wet. I never mist while in the container - the soil won't dry out while the lid is closed. I have killed many cuttings because they are too wet and rot or get moldy/fungusy. if I see the soil is getting dry I will add a tiny bit of water. I like the plastic cups so I can see the roots, but have also used the peat cups - you have to been very careful about them getting too wet. LOL. Try not to open the lid too many times although it is tempting to look every day. I have had cuttings take 3 or 4 months, as long as they are green, they are ok. Believe it or not, they can sometimes root in the dark! that happened once when I gave up on some and turned the lights out over the winter. I have NEVER had success with the baggy method, but that is just me.

One other thing, I use this method for many things other than roses. If I break a stem off something, it goes in water or into my propagation chamber - sometimes in both the see which works best.

I mist mostly for my hydrangeas as I use the same container for both. The peroxide helps keep fungus down and misting keeps me from having to water them much. Hydrangeas love water. My rose cuttings only rot when I used Miracle Grow potting soil and they were too wet because the MG does an excellent job of holding moisture. I have to use it straight out of the bag and not water it at all because it holds moisture so well. It is usually moist enough right out of the bag.

Also I haven't used the baggie method yet, only the plastic tote. I actually just started 3 cuttings just today with a plastic baggie because my tote is full of hydrangeas and some clematis so we shall see. My son broke a branch off of my Iceberg rose bush (it's still small and fragile) so I'm hoping that cutting will take root. The others are some type of red groundcover floribunda that is growing in the courtyard where I work.

As I sit typing this, on my desk are some Blush Hip alba blooms and the fragrance is heavenly. I'd love to propagate this bush, my dream is to place them all along the back of my property line as a flowering rose hedge, separating it from the wooded area behind it. I've heard that albas are not easy to propagate though. I have propagated my polyantha fairies, but no luck with my Rugosas. Any tips for these supposedly harder to root roses? I rooted the fairies in coir, that worked well. I've never tried rooting with bottom heat although I do have a heating mat. I will try that this time, but any other tips are most appreciated.

When we were doing a lot of rooting, we never managed to figure out albas. I'd definitely try layering. I keeping meaning to try that with the big Moyesii that may be too near the road.
