lst advice

is it as simple as bending them over and staking them down with a u shaped coat hanger or some such thing.

yep...that simple

just make sure the main shoot is no longer the highest and the main growth hormone will be distributed among the rest. if the main shoot re-takes over the highest point just tie it down again. there are also some people who stake down all the bigger shoots individually, either way has a positive effect imo.

also make sure you have a straight coat hanger to stick in the ground and zip tie/ect to secure it, this acts as a counter "weight" that way your shit don't uproot or snap

drill 4 holes or 6 holes equally spaced in your pot and use zip-ties as loops...stick the zip-tie through the hole and bend your plant over and secure the zip tie loosely. then just wait for the top to grow back up and work that Sl*t around the pot till you got her all the way pack to the starting bend and then she will start sending her oxtosin to her lower nodes and that'll start the bushing massacre
