what is eating my rose leaves?
Comments (5)If the rose leaves are "skelatonized" where the veins are left behind then it sounds like Japanese Beetles. They love roses. The leaves will look like lace after being eaten with all of the green gone. If it is JB, then insecticidal soap will have no effect on them. That only works on soft bugs such as aphids, lacebugs, mealybugs. Organic methods of killing JB would be something strong like pyrethrins or neem oil. Grub control is also very important. There is a parasite of grubs called "milky spore" that eats the grubs and spreads through the soil to infect other grubs. It may take a few years to have very good control with this. Perhaps a multi-stage effort to kill out as many adult beetles as possible and also work on the grubs. Good luck!...See MoreWhat is eating my roses?
Comments (5)Thanks so much. I googled it cause I had never heard of them before,.. very interesting. It has since moved to my lilac also....See MoreWhat is eating my rose bush? - not cutter bees.
Comments (5)Whatever it is, I think I have the same thing on one of my cherry trees. The leaves look eaten the same way. They leave the middle vein (and some side veins) alone on the leaf and just eat the green parts, and it's always on 1 branch. I'm guessing it's some sort of caterpillar. I was thinking of using BT but I haven't noticed any new destruction in a week. I just figured if it's not endangering the tree, I'd leave it alone....See MoreWhat's eating my rose leaves?
Comments (10)Rose slugs are part of the big picture of growing roses, and if you have the patience to wait it out with minimal measures like squishing/removing the worms (if you find them), and spraying with strong streams of water or the insecticidal soap to remove the ones you can't see, it will pay off in time. The good bugs like the wasps Patty describes will come in to eat the worms and you won't see the damage from there. That's why you don't want to spray pesticides for these. I don't think the slug bait works on these types of bugs, since they're not ground crawling slugs like the bait is for (those soft bodied squishy beige lumps). These are only called slugs in names, but they're actually larvae of a fly so they don't live on the ground. That is why you're not seeing improvement from the slug bait, lkayetwvz5 - you'll need to spray some water at the leaves themselves to dislodge the pests. The leaves themselves will still have whatever chewed parts they have, and it doesn't hurt the plant to leave them. Once you tackle this generation of slugs, the new leaves should grow in fine.
