Easy enough, I thought. I'll just trim the bushes and take my blower to the red lava rock landscaping and blow all the clippings into the yard prior to mowing. Well, I did just that and it took three seconds to find out it wasn't a good idea. I started with the blower and I was blowing the lava rocks out of the flower beds and all over the yard. I tried to vacuum the clippings, but the lava rocks would suck up to the vacuum also. I ended up cleaning the beds by hand, feeling dumb and frustrated. Other guys have told me they lay plastic down and then trim over the lava rock, but when trimming evergreen bushes, the needles tend to go everywhere any way. Is there a trick to this that I am over-looking? Any recommendations? One idea was to water the lava rock down prior to trimming the bushes. Appareantly, the lava rock should hold the water and weigh it down enough to use the blower afterwards. Sounds good, but almost too easy. Let me know if you've ever had this problem. Thanks!
