Privet trimmings as Mulch?????

Depends how woody the trimmings are, which of course depends on how often you trim your hedges (thought I was hard done to with a 100 foot rear garden surrounded by privet, and more in the front garden.)
Also depends on the weather to some extent, although that equally applies to other types of mulching materials.

In any event the leaves tend to rot far quicker than the stems, but overall I don't think mulching is a bad way of using excess prunings.

Not likely to be a problem, but privet is poisonous to some animals if they eat it, especially the berries if you have let them get to that stage.

Thank you very much JayG and Sunshineband, I must admit, I was tempted to go down the mulch route, but wanted other comments first.  , Certainly under the new hedges first and then on the brussels and cauli's .thank you. arh.
