The Many Foes of Roses
What’s eating your roses? On the latest You Bet Your Garden, Mike McGrath dons his detective’s cap to pinpoint the perpetrator chewing on them now…and details how to stop Japanese beetles from finishing the job later. Plus, your fabulous phone calls!
Question of the Week:I’m fairly new to roses, so I planted three ‘Knockout’ variety roses I’ve been assured I cannot kill. But it appears that something still finds the leaves very tasty. I’ve attached a picture. What is eating my leaves and is there anything I can do to stop it? I haven’t seen any Japanese beetles and it seems like whatever is happening happens overnight.
