Hi guys, I have two rows of Gros Bleu for a total of about 100-ft of hedge trimming that are about 4-5yrs old now. I'm still pretty much a young guy, but last year my Southpaw was speakin' to me after a marathon session with my Felco's. I've been mulling over buying a nice new gas-powered hedge trimmer to get both the lavender as well as the grasses, but now I'm wondering if a good old-fashioned handheld hedge shears wouldn't be even better? I've read that besides the maintenance annoyances with another gas-powered machine that they can create quite a mess when it comes to clean-up. I generally dislike powered tools and am a bit of a Luddite in the garden. The internet is full of ridiculous simplicities about how to prune lavender and that is definitely not my question. As usual, I trustfully await your experienced responses!
