Holes in leaves

Tom68

I have holes in the leaves of some rose bushes, a climbing rose and a climbing hydrangea. The plants are all about 10m away from each other. I can’t see any bugs on them. Does anyone know what this could be and if it’s something I need to treat before the damage gets worse, or just cosmetic.

Those cuts are caused by leaf cutter bees collecting their circles of leaf to bung up their nests.  It happens to most leafy garden plants at this time of year and nothing to worry about.  The bee uses these "circles" to bung up their homes once they have laid eggs.  The eggs will hatch out in the Spring - you can find lots of information about this on YouTube or Google. @Tom68 Even if you don't have a bee hotel in your garden you will find that the bees will use an old tree stump or other suitable places to lay their eggs.  Our hotel (we have 2) has a few leaf cutter bee bungs and we are trying to tempt more to come to fill the remaining holes and yes our leafy plants have circles cut out of them just as you do.

Lovely if you have leafcutters @Tom68

Vine weevils also make notches round foliage, and are very much not wanted,  but the size and shape of those suggests the bees, as @Guernsey Donkey2 says

Thanks thanks both. Nice to know I’m helping the bees out! Having looked again at my hydrangea there’s a lot more eaten away and it’s not the neat circles like the roses. I think vine weavil May be the problem. Another photo attached. Oh dear!

I agree, leaf-cutter bees on the roses but adult vine weevil damage on your hydrangea, unfortunately.  Vine weevil nematodes would be worth watering over your beds and pots and the weather is perfect for doing that at the moment.
