Thanks for the advice Alder. Will make sure the ivy is completely dry! I did compost the eucalyptus leaves last year and they were fine. My problem at the moment is that I needs loads of mulching material right now, but don't have the budget to buy
straw. The only things I have available are the mimosa leaves, a shed load of ivy that I need to cut back and then the eucalyptus leaves later in the year. Oh, and I forgot we do have some palm fronds. We got hit in here in southern Spain with a beetle attack that killed all the palm
trees Luckily we only had the one palm. I think I noticed that
Geoff Lawton was using palm fronds in his greening the desert programme.
