how-to root from a cutting...
Wondering the right method to root from cuttings from several different woody shrubs (gardenia, oakleaf hydrangea, pineapple guava).
I am new to propagating, and appreciate the advice. I do know how to root from softer plants in water, such as rosemary, but would like to start some cuttings now for the fall swap from some of my woodier shrubs.
Some additional questions would be:
what kinds of shrubs have y'all rooted from cuttings?
is there a general rule of thumb as to what can be propagated in water, versus plants that require the use of a soil medium?
How and when to use a rooting hormone?
Size of cutting to take?
When to take the cutting - after shrub has flowered?
