I don't know of a calendar per se; but I do know that most forms of propagation are best performed in the spring, or the season when the plant is growing most vigorously. It is not a good idea to try and propagate at a time when a plant is dormant.

I want to know how is the best way, not when.

I believe that you'll have much more success with your query if you'll use the current botanical name instead of the very ambiguous common name. Often it is quite simple to determine the botanical name by typing the common name in the Goggle system. I believe that you'll find that many,many plants bear the same common name and no useful information may be gleaned based upon a common nme.
Best of Luck
