Rose Propagation & Exchange

rose cutting in plastic bag

9 years ago

I've taken 2 cuttings from a rose - picture attached - and found instructions on the web for taking cuttings in summer, by putting in moist compost & perlite in a zip lock bag. (http://www.heritage.rose.org.au/warm-weather-rose-propagation.html) I hope this works as the rose belonged to a relative who has died. Should I keep the bag inside? Has anyone tried this method?

I took one cutting, and had a 100% success rate with this method. I dipped in rooting hormone and stuck it in soil in a clear pot (soil pre-moistened with water squeezed out). Put the whole thing in a gallon ziplock bag and sealed it. Keep it out of the sun and heat/cool. As long as you see condensation in the bag, it will not need to be watered. It took at least 3-4 weeks in the warmth of the summer to root. It's happy now and I look forward to putting it in the ground this year.

There's a lot of info on this forum, so you should browse around.

But for me, I've used the grocery vegetable bag with potting mix and bottle on top method (bottle method), cutting has to be at least 6 inches if not more, stem at pencil size or 1/4" at least thick, rooting hormone. And then I need lots and lots of luck, cus my success rate is about 5% out of all the ones I've done these past two years.

Other successful people have used other materials (sand/starter potting mix, perlite, etc).

Good luck! And if it starts turning black, it's a goner.

If you're new to roses, I would plant them in 5 gallon black plastic nursery pots with a good potting soil such as Supersoil, after soaking them for at least a day in water, and then watering them frequently. This way, you can keep the plants well watered and not have to worry about digging up hard soil in the winter, or stressing out the roots with inhospitable conditions. I leave the new growth on the plants, it shows that the plant is healthy and moving up nutrition from the roots to the new shoots. Being in plastic bags mean the roots are small enough to be happy in a pot for at least a season, or when the ground is softer and the plant bigger. If you plant in pots, make sure the potting soil is watered well before putting the rose in the pot, and firm the soil around the roots so there are no air pockets. I have pretty good luck with "body bag" roses this way.

Plastic bag or paper bag for seed storage

The folded paper design I posted earlier, I use only for temporary storage or for mailing seeds. If you are having trouble folding it, it is usually because you do not turn it over as directed in picture #3. For long time storage I use the plastic air tight containers used for diabetic test strip storage. They are a little smaller than the old 35MM film shipping cases. Dr. Norman Deno in his many years of seed experimenting found very little difference in life expectancy between seed at a constant room temperature and that at refrigerator temperature for most seed.

As I said above, those of us who adore 'Cl. Peace' are members of a distinct minority :)! This rose IS something of a 'problem child', but I've found it to be very responsive to TLC. A heavy feeder, 'Cl Peace' seems to have a preference for organics like fish emulsion, kelp, alfalfa tea. When I get my annual load of stable manure, 'Cl. Peace' invariably gets the first helping, and I try always to hold some in reserve for a second, late season application. IMHO, it's worth the extra effort.

Ok just wanted to post a follow up. I got my new cuttings and used my new products... the perlite and dip & grow. I got a ton of semi-hard wood cuttings. Cuttings: 4-8 inch range, striped all but a few leaves at the top, used a 50/50 mixture in 3 pots of my old sand and peat mix with the perlite, poked a hole with a dibber, dipped cut tip in rotting hormone, put my cuttings in the holes, moistened soil (not too wet) damp, kept in location that sees light, but not direct sunlight. (only bad thing was due to time issues I had to leave the cuttings in water longer then I planned before I prepared them and got them set up in pots) This time I left off the bags and instead misted in the morning before leaving for work and when I got home from work in the evening. The leaves browned on me still and I was about to give up and a few days ago 2 gave me some green leaves. So I have 2 out of about 30. I guess that is good considering I have no greenhouse and can't mist them more then 2x a day. The question now is leave them alone and kep doing the same thing and let them get stronger or try to take them out of the rooting pot and into a new pot of their own? I'm leaning towards leaving them till I know if any others are going to try and throw up some green. I worry about the delicate roots and trying to separate them out w/o damage. When, or do they even need to be transferred to a new pot with a different soil?

Well one has survived .. I put them in the plastic bag in a corner of the garden and have now planted the one with roots in the front garden which faces north. There is quite a big shoot coming from the base.

should I fertilise now, or wait till sept-October in spring?

also, how long does it take before flowers appear?

Congratulations, that looks like it will do good. I don't believe anyone recommends any fertilization until your plant is more established ... and depending on where you're located, you might have to worry about winter. I'm sure everyone else will have some good suggestions for you!

Generally hybrid teas are 6-8 weeks regarding bloom cycle, so probably 8 weeks for you, except you might want to disbud to encourage root development.

Good luck.

It would be great to get some flowers this summer (I'm in Sydney so winter nearly over). I don't think I'd have the self discipline to disbud! Margaret, whose rose it was, died last November. It would be amazing if it bloomed for her anniversary

That looks great. Good job. I would give it root stimulator (starter fertilizer) if you can get it. Miracle Grow makes a good one. It encourages root growth. Sometimes it will say "reduces transplant shock" and that's the one you want. That will get it up and running quickly and won't harm it if you follow the directions. If not give it a very diluted fertilizer about 1/4 the usual dosage. As long as it's getting sun and the temps are warming up, fertilizer will do it good. Just be sure it's not full strength.

Thanks .. I don't think that brand is available in Australia but in any case, I have worm pee and castings, and Seasol which is a good seaweed root stimulator as well as Dynamic lifter (based on chook poo) and blood and bone, and cow manure and ordinary fertiliser!! Will just use the first two for now, it is growing incredibly fast without anything, I can't wait for it to flower.
