Hello all - new member here (surprise surprise!)
Not a newcomer to the pastime, but not an old hand by any stretch of the imagination either!
Currently doing some secondary development on my Cedar of Lebanon and wondering if anyone has ever used the subsoil tourniquet method to thicken a trunk base, and if so, what advice / tips would you give? Have looked online but does not seem to be a much talked-about method these days - has it fallen out of fashion? Tree is nice and healthy currently, having a good old period of growth spurt this year so far... Quite happy with rest of trunk for its tender age, but a flair at soil level would look much more natural to my eye I'm not looking to embark on this until next spring so no need to trip over each other in the rush to reply! 'Scuse dodgy wiring "technique" with previously enjoyed wire - just fooling around with overall shape before committing to do it properly with new wire... also 'scouse quality of attached pics - poor camera phone and slightly shaky hands do not a good combination make!

Best place for a small tree like that is in the ground. Tourniquet is usually used to grow roots, or alternatively it might make a literati.

Thank you kindly!
Sadly, not got anywhere suitable for it in thet "plantable" area of my garden... currently got it in a 52 x 42 deep seed tray with good drainage. Roots are running amok in there and VERY healthy! Trunk has thickened measurably in the two years that I've had it (the "before & after" difference in the two pictures) Stupidly, let heart rule head when deciding which branches to keep/ develop and have only avoided inverse taper by more luck than judgement! Trunk is almost uniformly thick all the way up due to this however, hence want some flaring/swelling at soil level to look more natural. Paul Lesniewicz alludes to tourniquet method in his book for this but details are a bit scant...

Very good progress actually, the torniquete is used to develop side roots on the top of the torniquete as the plant thicken tru' it, and as the side roots thicken, they'll give you a bit of a wider base and more tapered.

I think it would be similar to prunning the taproot when the tree is young, and organizing it's side roots when potting, but for trees that passed this stage, or wouldn't take such a drastic procedure.

However I've never tried the torniquete...
But it's for the base tapering only, for tapering the rest of the trunk you should go for sacrifice branches techniques.
Changing the leader and etc...
For conifers, sacrifice branches are very often turned into jin.

That's brilliant Albas, thank you!
Love the reference to jins - did a couple on this juniper (still a work in progress) that I rescued from a good soul that had lost heart - the branches looked just like lollipops, there was nothing else that could feasibly be done with them unfortunately... My first and only attempt at jinning so far - my word, what a heart in the mouth moment that was!
