I have a huge macrocarpa hedge around my property. It has good points, but it's expensive to get cut. I've found that the hedge clippings are great for eliminating lawn so you can turn it into a garden. The green bits turn into good soil very quickly. You have to remove the woody bits before you start planting. No big deal. But the fascinating thing is worms love the green bits, especially the green stems. One evening I went to put something in my letter box and I saw what looked like a tiny macrocarpa forest. Worms had pulled the little green bits end-on into the ground and were chomping on them in the privacy of their own burrows, enriching the soil. Has anyone else seen this? I swear I hadn't been drinking.
