Hey everyone. I am starting a new customer tomorrow and they planted vinca minor (periwinkle) in small planters alongside other shrubs. I have a lot of trimming to do to get it caught up and under control, but I fear I will get tired of trimming the periwinkle by hand. I am afraid my string trimmer will tear the vines and give me a shabby finish, but my power shears are too big for the amount of trimming ( not to mention it is all at ground level ). Here's the big question... Are there any electric hand shears that will get the job done? Black & Decker makes a cordless combo (interchangeable grass shear/hedge shear) but got poor reviews. Any advice will be appreciated. Thanks !
