For cuttings, I use seed starter or just plain peat moss for soil. I fill up a 2 inch (about 5 cm high) seedling pot.
We can use yogort cups or recycle other things too. After filling up the seedling pot with peat moss, I wet it twice to make certain it is a bit like mud all the way through. Then I let it drain well.
Now, I am going to say something shocking:
After draing, I then pack/ tamp the soil but only medium-light. I know everyone cries, “but cuttings need fluffy soil!”
Tamping/packing the soil makes certain the cutting stays put and doesnt fall or twist around in the pot and never root.
When I take a cutting, I get a stem end that has 4 to 6 leaves. The bottom two leaves are removed. This is where future roots come from.
Next I use the wrong end of an artist paint brush to place 3 holes in the wet seed pots. The ends of cuttings are dipped in water, then rolled in the rooting hormone powder.
We want to make certain the cut and the place where we took off the bottom two leaves are covered with the powder. That is where new roots will form.
As I place each one in its hole, I am very careful not do it in such a way that the rooting powder is wiped off. (Dont twist the cutting into soil, or shove them in a hole in the soil that is too narrow).
Last we press the soil a bit tightly around the stems of the cuttins by pressing from each side. We want to make sure it is firm, and the cutting does not twirl or move in the soil.
At this time, I do not water. The soil is alreay wet and and we dont want to wash the powder off the cutting below the soil surface.
If there is a bright humid place that never gets direct sun, then that would be ideal.
I dont know how dry is the air where your at, but I usually have to water cutting once about every three days.
I put three to a pot becuase not every cutting will make it. However, 1 in 3 usually does take root. We also need to make certain cuttings are completely dead before trashing them.
Many cuttings will look terrible until they form roots(wilting).
After potting them the first time, I dont keep them in superwet muddy soil. Evenly moist will do fine, but humidity really helps.
