I use Preen in my paths to keep the annual weeds down. Without it I'd be spending half my summer pulling weeds. It will not work on perennial weeds or things that are already growing, as stated above. It does last a good 3 months or more, so timing has to be right to 1) stop the annual weeds before they germinate in the spring; and 2) have the longest lasting effect as possible. It's possible on zone 6 you will have to reapply it in midsummer. I can usually get by with one application per growing season, but by the end of the summer I can tell the effect is wearing off, esp. if we have had a lot of rain.

I try to avoid chemicals as much as possible. However, the weeds in Florida are getting the better of me. I have a mulched area that I'm considering "Preen-ing". I'm also trying to get groundcover to grow there. Will the Preen inhibit spider plants shoots from getting roots? What about plants that I transplant? Will the Preen hurt them? Thanks, Lynne

I just bought this tractor,got it home started it and rod went thru side off motor,so never had a chance to really run it,found another motor built same year 1988 but 12 hp so installed that (came off a Huskivarna) could not find a reg on that mower either,so figured it would work,same carb and coil.Ran it and cheaked battery just because and noticed that voltage after approx 10 min would creep up to 16.5 running full throttle,so adjusted the throttle with lil change,at idle was 15.5,so pulled the flywheel and installed the altenator from the 11hp, (note 12 hp half circle Alt with one red wire,11hp original engine had 2 wire full circle, mower has lights) flywheels were different but same size magnets.anyway same problem,16.5 volts.Battery had a standing voltage off 12.7 (off my snowmobile) tested diode and current only one way,AC upstream of diode was 28vdc,i am concerned about blowing up battery.I dont see a typical fuse in the wireing or schematic unless its a lil black box beside the solonoid with 2 wire connections.thx waren

Embothrium, I live a good 25 miles from the ocean in the San Fernando Valley. It's moderately to extremely hot, dry and windy in the fall, spring, and summer... cool to cold and mostly dry in the winter. Almost never foggy. We're still in the middle of a severe drought to boot. Even if it could survive here, it would probably outgrow my yard and become a potential liability in the not so distant future. If it weren't for the drought, I'd consider the SoCal coast, but who knows how long it's going to last. Tom, I don't drive a Prius. But I *do* drive an Elantra hatchback haha! I've always loved trees and I feel strategy responsible for this one in particular. It's the only tree I've ever taken care of. I'm gonna have to get one better suited to my climate to replace it when it's gone :/
