My friend Ken is quite the gardener. He must be feeding his entire neighborhood with what he grows: nectarines, oranges, grapefruit, peaches, lemons, squash, beans, tomatoes, eggplant, basil, oregano, more basil...
But the hedge. I've never seen a hedge like it on private property. And Ken trims it himself, about three times a year. He's created an efficient contraption with painters' ladders, chains, boards and a frame. His trimming shears are sharp. He's fast.
The hedge plant, in case you're wondering, is Eugenia. It can grow as high as 20 feet. Ken's about 6 feet tall. Yesterday we figured the hedge is more than twice as tall as Ken, maybe 14 feet (14 and a half when it's not trimmed). Los Angeles County has laws about fence height at street-side, but as long as your neighbors like it, (and his do), hedges between neighbors can be high.
I'd talk to my neighbors about sharing a Eugenia hedge, but right now I'm having trouble keeping my grass alive so I'm taking things a step at a time.
