Freshly cut willow - using as plant supports?
Hi, I've cut loads of willow back today as it had grown into a beast - it's the type that is planted as whips and used as a type of hedge. I don't know any more than that as it was the previous owners who planted it.
Anyway, some of the stems I've cut back are the perfect size for plant supports - like proper willow sticks/pea sticks etc. However I need them to die off first, otherwise they will just root as soon as I stick them in the soil.
Is there any way to kill them off quickly so I can use them in the next couple of weeks? Or do I have to wait and store them somewhere for a long time before using them, to kill them off? I guess I was thinking about putting the ends in boiling water to see if that works (I don't want to use chemicals), but is that utterly pointless? Any tips?
