NOTHING but the Potting Mix.
I want to share this last method that worked for me with no failure.
I still deep the cut ends of the cutting in melted Paraffin to prevent Rot, Disease, Mold, Fungus and Infections on open ends.
Material needed:
* Potting Soil (Home Depot)
* Clear Containers (from Smart & Final)
* Plant Cuttings (from F4F Members)
* Water (preferably Filtered, specially Reverse Osmosis)
* In the first watering I also add liquid Vitamin B1 for strong rooting (from Home Depot)
* No Rooting Hormones, No other Chemicals and No Pesticides!
I chose this particular brand and type because it has 30% more Moisture Control and 6 months worth fertilizer.
After making 4 holes under the potting container I fill it with Potting Soil and stick the cutting in the middle of it.
Then water it and put the top cover loosely , which is another Clear Plastic Container with NO holes on it.
With some situations, like bigger cuttings or branched cuttings, you can get creative and find different hight and size clear plastic containers for cover just like in the pictures bellow.
Place the covered containers in a sunny corner in the backyard but make sure they get some shade as well. (I use my portable Palm Trees for shade.) The heat of the sun makes the cuttings root very fast, I have seen some cuttings root in as little as 4-6 days. You don't need to water them for a very long time, since there will be very minimal moisture loss due to evaporation.
Every few days you can open them and check on the cuttings and let the dew drip back in the container with soil and cover it again.
After they have rooted, you slowly start removing the top containers and let the top growth sun-harden to be ready to face the world (Outside Elements).
Sometimes you might see one starting to welt a little, just put the top cover container back on it and in short time it will be back to normal.
After 2-3 months you can up-pot them into 1 Gallon pots.
That's it! :)
. I have produced my most valuable cuttings this way and haven't lost any.
. With Baggie method there was a lot of fungus, mildew, mold and rot to deal with. Was too much work.
