hi. Im thinking of perhaps using outdoor mist and a sandbed for propagating easy shrubs, mainly potentilla. How many cuttings a year would you need to make for it to be a good investment? I sell perennials at small local farmers markets.
I live in ireland. I can see this method would be great if i lived somewhere arid. Is it so necessary here?
If mist is so great, why does it seem so complicated to get a cheap pump and timer- why isnt everyone at it?

What advantages are there to using outdoor mist? I have large coldframes that are mostly empty this time of year, if used those and hand misted 2x a day would i have good success? Any advantage If i rooted into compost insted of sand?

What percent losses would you expect with mist compared to other methods. Whats next best?

RE: mist

The best combination for fast rooting of cuttings I have found is 1. a medium with a maximum of air to water such as one heavy with perlite.
2. The ability to maintain root temperature warmer than air temperature, usually with bottom heat, at least 70 F.
3. Maintain high humidity to prevent drying out of the cuttings before they can root. Misting is one way to to do this. The frequency of the mist required will depend on the enclosure, and its ability to maintain the high humidity required. Al

RE: mist

thanks al. What do you grow? I guess its pretty warm and dry where you live? Do you do your cuttings under glass? What do you mist with? How many cuttings do you make?
Same questions for anyone else who's reading...
Thanks again, charlie

RE: mist

I use a Mist-a-matic that was bought second hand.I built a little frame out of PVC.This supports the misters and is draped over completely with clear poly film.
I also made a version of a propagating box that is shown on Youtube.Here are pictures of mine and a link to the original.
Both the M-a-m and pond fogger way work fairly well.
I grow a lot of Blueberries and first tried putting a baggie over the cuttings with minimal success and it seems that they need more than a couple sprays a day.At least Blueberries do.
I've done other plants too,with both methods.Brady

I've wondered about those pond foggers. Do you use distilled water in the tub? Do you circulate the air inside or does it not matter? I've notice the fog from those tends to settle.

RE: mist

I use tap water and put a little Hydrogen Peroxide in it to help keep the algae growth away.
The top is lifted about once a day to allow some Carbon Dioxide in.
The vapor does settle on the leaves. Brady

RE: mist

My success rate using intermittent mist has drastically gone down over the last few years so I have researched using fog and set up a small unit. I am anxiously waiting to see what success I might have.
With my mist system I have tried all kinds of growing medias, even straight Perlite.
