Airlayers are not always possible, and some time it is better to resort to truncheons. So far I had very good results. I actually dont remember loosing any...but that is because I forget things I dont want to remember.

I am naturally a hoarder...so I can not throw easily a cutting...as a result...I probably have....(please dont laugh) 10000 or more. But I give away freely...and planted the gardens of all my neighbors. Started planting their gardens long time ago...so my neighbors will not hesitate to let me dig anything from their gardens...and if anything needs to be removed they ask me first if I want it.
Also my kids are in real estate...so they build houses for rent and sale...many! So most of my plants are designated for those houses and that makes me happy.
When do I take them? Which time of the year? Most of the time...We dont have real winter here...so perhaps in winter I slow down...but juniper cuttings root best in winter.
I dont use any rooting hormone...but use occasionally honey...I plant everything in coarse sand, and some difficult ones cover with plastic dome.
So far I managed to root everything...just the % are different...If I really want something I just take more cuttings.
Some plants do better from small cuttings some do better from truncheons.
I have been doing this for the past 30 years...I used to have 3 garden centers that I grew everything for myself. Now I closed them long ago and decided to rest...but it seems resting is not that good for me...and I might open them again...or just one to keep me busy.
The trick with truncheons is to take long cuttings...the bigger the diameter the longer the cutting I take. Some I take up to 1m long...
Here is a picture I took in an African village...This are assorted poles cut from the bush, and stuck in the ground.Notice that most of them are growing.
