something's eating my rosebushes?

Question

there are little circle bite marks all around the leaves of my roses,does anyone know what it could be,I mean one of the bushes is completely eaten!

Answer 1

Could be a leaf cutter bee or Japanese beetle. Rarely do leaf cutter bees defoliate a bush so it is probably the work of the dreaded Japanese beetle. I'm sorry about your bush but is should make a come back by the end of the season. Just because the leaves are gone does not mean it is dead.
Here is some information about the leaf cutter bee and the Japanese beetle. Hopefully it will help you now and in the future.

Just remember that using a pesticide like seven will kill the beneficial bees as well as the leaf cutter bees and that is bad. The number of bees are dwindling as we speak so we hardly need to kill any more.

The Japanese beetles can be hand picked and dumped in a pail of soapy water.

There's several pests that can be eating your rose leaves.
Leaf-Cutter Bees use the leaf cuttings to build its nest. Chemical controls are not necessary as they do not harm the plant and are rarely more than a minor nuisance.

Pear slugs are the larvae of the sawfly. They eat holes in your rose leaves from the undersides. Slugs can do a lot of damage in a short amount of time, so act quickly. Galic spray is great for getting rid of slugs, cutworms, wireworms, & whiteflies. Blend well 1garlic bulb & 1 onion add 1Tbsp cayenne pepper & 1 quart water. Steep ingredients for 1 hr, then strain & add 1 Tbsp dish soap and your non-toxic spray is ready to use.
Long-term prevention & deterrants for slugs: Spread coffee grounds( in moderation) around base of bush. Use repellent mulches: Wormwood, prostrate rosemary, basil, rue, hot pepper, acacia bark, and oak leaves are disliked by snails and make good repellent mulches. Wormwood is also effective as a spray. Use barriers with scratchy material, hydrated lime, wood ash, sharp sand, crushed egg shells, or diatamaceous earth.

Japanese beetle also eat leaves. They lay eggs on your lawn and around your roses and return year after year. You can use a neem-based product to get rid of them or you can position a bowl filled with dish soap and water under the rose and tap lightly. They should fall out and drown in the solution. This procedure seems to be most effective in the morning or evening when the beetles are resting. Another procedure is to spray infected plants with a mixture of 1 tablespoon isopropyl alcohol to a pint of pyrethrin mixture every 3 to 5 days. Long-term prevention for Japanese Beetles is simular to that used to kill the Rose chafer larvae... biological controls such as beneficial nematodes or a product called "milky spore."

Earwigs are a large and soft-bodied yellowish-brown insect with a pair of curved pincers. They hide during the day and come out at night to climb into your rose blooms and feed. Traps such as corrugated cardboard; rolled up newspapers; small cans with openings punctured in the ends can be collected in the morning & the earwigs disposed of.

Caterpillars, the larvae of moths and butterflies can be picked off & discarded. Or sprinkle with flour when the plant is wet & they'll become coated with flour, suffocate & fall off the plant.

Good luck! Hope this helps.

Answer 3

Wizzle is correct... it's leaf cutter bees. Using a residual pesticide, such as Sevin, works.

They were chowing right down on my bushes last year, and we discovered they were building their nest (with the leaf pieces) in the framing of a bedroom window (between frame and window itself so when we opened it looked like someone stuffed old leaves in there).

Answer 4

It's a result of "leaf cutter bees."

Answer 5

Sorry I will stop that and move on to your other garden
