They will fall off on their own. Adding some flowers nearby to attract bees and pollinators will help, or you could just hand pollinate.

I already answered another post of yours, and it sounds like you might have already replaced the soil. (You can read my comments in that other post) Anyway, two things stand out in these pics: (1) no mulch (2) other stuff in the containers (lemon peels??) If you have pictures of the fungus that is now on the foliage, that might be helpful in diagnosing the specific problems you're now having.

I tried the alcohol and they didn't come off. Maybe it is damage from the sun. It's been extremely hot lately and the rose lost most of its leaves. I moved the rose today to a better location. It used to be in front of my house, where shade cloth is not allowed by my HOA. Hopefully, it will leaf out again. Thank you all for your help. If I ever do see scale, I'll know what to do :) Irisgal, I'm not sure why the new cane has such small thorns below, but there are larger ones further up.

If you are watering primarily in the cup, and supplying a dribble here and there to roots. All fertilizer salts are accumulating in the grow medium, which makes it continually more difficult for the plant to take up and move water efficiently. Eventually, as the level of dissolved solids/ salts in the grow medium continues to increase, water absorption will become impossible, or even act to pull water out of cells, reversing the normal process of osmosis and pulling water OUT of plant cells via the same mechanism curing salts 'pulls' water from the cells of meat destined to become bacon, jerky, ham, ..... . The technical name for what is occurring is 'plasmolysis', but more commonly it's known as fertilizer burn. The fix: Flush the soil on a regular basis. The grow medium looks very dense, so you might need to use something that allows you to flush the soil regularly w/o the need for concern the medium will remain wet too long and cause root issues related to either function or health.
