Propagating tips. was created by Mustangnin
Hi, its been a few years since I propagated some shrubs/ plants for my garden. I set up my small propagating unit yesterday after it fell into disrepair and am keen to get started.
I was wondering what media was used now? - do people make their own or buy ready made? I googled and saw Daltons have a propagating sand- not sure if its good. I will need some sort of rooting hormone. Any other tips I may have forgotten over time? Recommendations for books/ articles?
Appreciate any tips. Thanks.

This site has a quick run-down on the advantages and disadvantages of a few different rooting media.

I use a mixture of equal quantities of fine pumice and bark, mixed well, Best to keep moist but not wet.
I have never used rooting hormones, I prefer plants to develop good strong roots without chemicals.
I cant recommend books but am sure you could find good ones in your local library?

HI, I propagate many hundreds of plants, and we just use 3mm sand for the cuttings and seed. No additives, this warms up quicker than most of your potting mix type soils. The sand is cheap and you can throw it away or put it on the garden when you have finished with it. Good luck.

Cheers

Hey Helen, what's the depth that you use for propagating with sand? Is 5cm enough?

I discovered something interesting today. I had a seedling apple tree in a pot in the greenhouse and it hadn't been moved for sometime which gave it a chance to push roots through the bottom of the pot into the greenhouse soil. A friend helping me weed the greenhouse just ripped the pot up and moved it. Today I noticed it had grown three new little apple trees on whatever roots got left behind. Now, I knew you could take root cuttings, I just didn't expect an apple seedling to send up three new plants. Might pot them up, they look like strong survivors.

Did you know, that what you thought I said, was not what I meant :S

the only problem I would see with a sand only mix is it has no water holding capacity so while this could be an advantage in winter, it wouldnt work as well in the summer as the cuttings would quickly lose moisture as there is very little airspace in sand as well. Hence mixing with bark or peat to get something that holds water.
Professionals will use a misting unit but a spray bottle with water will help keep the moisture levels up if you are propagating in the dry months

Fine pumice makes an excellent medium for cuttings. It has good capillary action, so if the base of the pot is in shallow water, it will continue to draw water up as it evaporates off the top. Just top up the water tray when you see it's dry.

HI, 5cm would be the depth of our trays we use.We find if it dries out to quick especially when it is in the peak of summer, just mix a little liquid detergent with some water and water that into the sand. We have areas where the cuttings are under mist, and we have areas where they shaded are watered for about 20seconds twice a day with a hose. Cheers and good luck.

I'm quite pleased with the bag of Dalton's Cutting Mix that I bought when I had fig cuttings to propagate. I also used a liquid rooting hormone called Clonex.

Half the cuttings were jammed into a large pot of Cutting Mix. The best half were wrapped in plastic and carefully placed in the heated propagator.
Unfortunately the thermostat on the propagator broke down and it cooked them!
The pot of cuttings in the cutting mix were outside and weren't fussed over. A couple weeks ago I noticed that the cuttings were showing signs of life. The pot was removed from the orchard when a torch-llght inspection revealed a slug chewing on one of the shoots. The pot now has buds and leaves forming on all the cuttings in it! It is locked up at night out of possum's reach as well.

Results:
Propagator: Possibly one cutting surviving.
Dalton's Cutting Mix pot: 100% success (9/9).
Figs have a strong desire to grow, which is a great help! lol.

If you are near a HortiCentre shop the Clonex is a lot cheaper there than in the super market or from a hardware store or garden centre.

Next experiment is to see if my green cuttings of grapevines take root.

I had big success taking green juvenile cuttings off Plum trees and rose bushes in January 2013 and they all survived. Powdered rooting hormone. The secret is not to let them dry out. i chose pots that were not too big, and have some bottle cloches made out of ocean Spray Cranberry bottles (plastic ones) They fitted nicely inside the plant pots. I kept the bottle tops on initially and just topped up the water tray if it was dry. For a while I couldn't see anything through the condensation on the bottles, but when it was obvious something was growing, i took the bottle tops off, but kept up the water in the tray. They were in a sheltered posi by the house, where they got early morning sun only. that winter when leaves dropped, they were transplanted to the orchard and are starting to make some size three years later.

Just a thought? When taking cuttings from trees or shrubs a lot of them have been grafted and the scion or top growth can perform much differently to the tree you think your getting.

:) Hi

yes i'm here again after a long absence... :)
we have 3-4 huge shrubs with old roses who got a beautiful scent. They are planted towards the road and we would like to build a fence along to cut off the traffic noise a bit. Can i take cuttings of those and (try) to regrow them to put them somewhere else? And can i do it now in summer (very hot here at the moment 32°C) or should i wait till autumn?

Thanks
cheers

Try the method I have posted on this thread. I had success with roses too this way.
