Rooting

Here is my way of rooting my hoyas.

Get your cutting

start
These are my cummingiana cuttings I recently received that I'm going to use as an example.  Ideal cuttings are ones with at least two series of leaves, not new or very old growth.  If you have a long cutting, cut it in half to double your chances of getting roots.

Use Rooting Hormone

rooting powder
I use a damp ear bud/Q tip to get the rooting hormone from the pot to the cutting itself.
applying rooting powder
Apply to the bottom of your cutting, paying particular attention to the nodes (where the leaves come out).

Put cutting into Jiffy Pellet

I use Jiffy Pellets to root my cuttings.  These are small circular discs that are soaked in water to reconstitute.  You can use normal soil if you wish.

placing into jiffy pellet
Gently place the cutting into the pellet. You will find that the pellet should hold the cutting well. There is no need to remove any leaves but you might find that removing a couple at the bottom will help you to fix the cutting in the pellet.  If you're using soil, you might find you need to use some bent wire to hold the cuttings in.

Place into a resealable plastic bag

finished
Gently place the cuttings into a resealable plastic bag, on top of a saucer. Place the bag plus cuttings onto a hot mat. Close the bag, leaving approximately a third open.  This is important because, although a humid environment is beneficial to promoting root growth, too much humidity can cause mould growth.
Leave the cuttings on the hot mat for a week, watering every 2-3 days depending on how dry the pellets get. After a week you should be able to see roots.  Once you have several roots (1 to 2 weeks), then you can move on to the next stage.

roots!
Here you can see lots of lovely roots on my linearis.  Once you have roots, make up a plant pot of the right side (I usually use the smallest that will fit the cuttings in question and stay upright).  The soil I use is a mixture of ordinary soil, vermiculite and perlite.  You can use a pencil to make a hole in the soil for the cuttings to go into and gently place them in up to where the roots stop.  Once again, you might need a hairpin or some wire to hold the plant in the soil. 
I place my cuttings, in their new pots, back into the resealable bags as above. I usually leave them there for a couple of  weeks before starting to acclimatize them to the surroundings. To acclimatize them, I leave them on the hot mat without the bag around them until I see signs of growth.  Then I finally take them off the hot mat and find them a suitable space.
