Hi DF

In my humble opinion I would't bother with the plastic bag/sphagnum moss approach, but in saying that if it makes you feel good you go for it.....

What you really need to do is to spray the woody stems with tepid water as often as you can during the early part of the day (no later than early afternoon), this will soften the wood and allow the embryo buds to break from the stems easier.

As I stated in another thread, I am using a bio friendly product called 'Garlic Barrier' to spray my plants with at the moment. This acts as a stimulant and the bugs don't like the smell.

As usual with this kind of question it's a case of whatever is best for you.... let us know what you decide and how you get on.

Tight....
