We planted 2 QE roses bareroot early May and they grew quite nicely to almost 2.5 ft thru summer but then leaves started showing holes- typical bugs eating them I found out. Also had aphids and ants all over. We didn't do a good job treating them.
Anyway long story short- almost all leaves have been eaten up- although stems look fine.

Question I have is will leaves anyway would have fallen off this Fall? And will I see new leaves sprouting come Spring? Similar to deciduous bushes?

Thank you for your help.

Yes to both questions although some roses will hang onto their leaves longer than others. I prefer to remove them in the spring anyway so you're ahead of the game in that regards. What were you doing to try and help the situation? What's this black spot or bugs?

If you have nice weather for a while yet you may even see a few new leaves starting to grow this fall. Not to worry. Just leave them alone. Next spring when you prune they will leaf out again.

No black spots.
Saw white spots and then just holes, which grew in number and finally what was left behind was just veins of leaf, rest of the leaf is all eaten up.
Ants and Aphids were plenty.
Yet plenty of beautiful roses... like 25+ easily... for a bare root planting in May...
We bought this organic Neem oil spray but did not use that often... we should have.
We are brand new to roses---- never planted in our lives before so its a learning experience.
How do you remove leaves in Spring.... ? right from where they attach to the stem?

I began growing roses a little over a year ago. I used neem oil to control bugs of various kinds. It burned the leaves to a crisp. I removed the damaged leaves and my roses responded nicely. There are all kinds of products available to control critters and other maladies. I would never use neem oil. To remove leaves just grab them at the base and pull down.

I'm fairly new to owning roses, but I got a bunch this year and I had the same issue you did. I looked at the underside of the leaves and there was a little green "caterpillar" on them. It was pretty tiny, I had to use reading glasses. I wore gloves and squished them. Later I found out they are saw fly larva and if you get them badly, you will get them again in about a month or so. I have taken to inspecting my rose bushes for the "white dot" leaves then finding the larva. My roses are very small and new, before I knew what was eating them, I almost lost 1.

@Sandsock... my roses have grown quite a bit just in 4 months. It's just early May when I planted them bare root, just about 3-4" of canes. Now they are more like 3 ft tall, not very bushy yet but I guess that will happen in years to come.

I think I have the same problem you describe, although I have not seen these larva you are referring to but almost all the leaves are completely eaten up, but canes/ stems have no issues. So, I am assuming that the leaves will come back up in Spring.

I am wondering what I can use next year to make sure I dont get the same problem again.

Thanks
