Treating insects/pests

There are holes in the leaves of my Knock Out® Rose. They are not only on the edges and I don't see any beetles or other bugs. They are not symmetrical holes, either. Any tips?

The leaf damage you are seeing could be from what's called rose slug (also called sawfly). Look on the underside of the leaves. Do you see any tiny green inchworm looking critters? Rose slugs will chew the leaves of plants--leaving trails where they've munched through, but they won't be detrimental to the overall health of your Knock Out® Roses.

Japanese Beetles are attacking my Knock Out® Roses. What should I do?

Pick each Beetle off and drop them into a bucket filled with warm soapy water. Putting a bird feeder nearby may also help. Japanese Beetles won't be detrimental to the overall health of the plant so if you can stand them, it's fine to leave them alone too. You may want to try a product like Milky Spores to control them--we recommend just pulling them off one by one though (not fun but effective)!

Do we need to protect our Knock Out® Roses from being eaten by insects?

Knock Out® Roses are not pest-resistant, but they are extremely tough so even if bugs get after them, they should be fine. You can use a spray product formulated for roses if the bugs are particularly bad in your area. The best way to remove Japanese Beetles is by hand though--pick them off one by one and put them in a container of warm soapy water. Placing a bird feeder nearby can also be effective!

The deer have eaten most of the blooms on my Knock Out® Roses. Will they bloom again or are they a total loss?

Knock Out® Roses are not deer resistant and unfortunately, as you probably know, when deer are hungry, they’ll munch on anything. Don't worry though, Knock Out® Roses are really tough. They bloom every 5-6 weeks so hopefully when it's time for them to bloom again, you will see more flowers.  You may want to try a product like Liquid Fence to keep the deer away.
