So my rose bush leaves are coming in and they are "folded" as seen in the pic below. Some of my rose bushes have mildew, although I am winning that fight, now. It is almost completely gone.

So here they are, I don't know why these canes give leaves like this.
It's only this one bush. It's on one side of the bush, as you can see. When I fertilized over a month ago, I didn't use too much. I spread it around evenly. I water it evenly. So it's not getting one sided treatment. It looks as if they will eventually open up. But even then they are still a little folded. If anyone knows what this is, or if it's normal. That would be great.

I don't think it's mildew. There's no white mildew on the leaves. And I'm sure I saw the leaves coming in like this earlier in the year, before my rose bushes had mildew.

Water them some more. The soil looks absolutely dry. It also needs mulch to minimize the loss of soil moisture. Temps above 85 or so will start to bother the plant. When windy and very sunny, it may also loose moisture through all the leaves faster than it can absorb more water through the roots. Then the leaves wilt. But they are ok.

New foliage produces leaves that are various shades of reds. After a few weeks, they turn green.

New leaves that get exposed to late frosts can turn from green to red, red&yellow, etc or yellow if there is damage.

While this is common when growth goes into high gear in Spring, your new rose leaves can also develop this pigmentation when exposed to a lot of cloud clover or after pruning.

This is not Rose Rosette Disease (RRD) if you are wondering though. Red pigmentation does occur with RRD but you would also see sharply increased growth of small leaves and thorns forming clusters of unimpeded growth. That type of growth sometimes looks odd. For example, a normal stem would look its typical thickness but then beyond a certain point, the thickness increases markedly, there is a forest of leaves & thorns and then the stem thickness goes back to its previous normal thickness again.

Unfortunately, now (May-ish) is the time for the mites to spread the virus that causes RRD. It is close to you:

Those look like perfectly normal new red foliage. The soil does look very dry, however.

It takes several weeks for the new foliage to mature and turn green. Give it some time and you'll see they will flatten out then. Otherwise the rose looks healthy but do water it more, please.

Lol. I do water it haha. I'm not neglecting it!!!

From the responses I'm getting, it sounds like it's a watering issue. Hmm... I'm gonna have to think some more as to why or what's going on with it, that it's not getting its fill of water.

So this is the same rose bush as in this pic/thread.

The thread "What is this growing on my rose bush?" in Ask a Question forum

I'm wondering if that "thing" is stealing water and nutrients from my rose bush. And what options I have. I've been thinking about taking cuttings from all of my plants right now, since they are growing so well (best chance of them rooting) to have backups.

Hmmm...

I checked that thread: imho the "thing" looks like the new growth of an ornamental bush that I have here called Euvonymus. Whatever it is, you'll have to choose between the rose and the thing. If you choose the rose you will have to prune off all new growth of the thing until its gone. Its a bit too late to uplift everything and get the two plants separated. In fall that could be done.... Meanwhile, it would benefit your rose to get watered, yes!

The folding is normal from my understanding. I see it in quite a few of my bushes too. Not to bemoan the point already made but uhh...more water! Rolling on the floor laughing And throw some mulch down so the soil retains the moisture better.

Well I only care for the rose bush. That other thing can go. If I could save it great, but I'm not worried about it dying. I just don't want it to harm the rose bush.

I do clip it back. So it seems like fall/winter is the time to uproot them and separate them. I'm guessing because the rose bush will be in hibernation/dormancy...

Ok, so I'm watering for 2 for now. Thank you

The folded leaf is not a problem, it's normal. The water issue has nothing to do with it. It just looks like your soil is extremely dry.

Soul Reaver --- You are in Milpitas . . . Your roses may not go completely dormant there.

In fact, in MY part of Southern California, you prune to sort of force them into a "false dormancy" -- and they actually go semi-dormant at the height of the summer heat. (And you do get some brutal summer heat. Often even this early.)

I've been in the San Jose Heritage Rose Garden in mid-May when it was too hot to walk around the garden, and all of the volunteers packed up and went home. This was morning in San Jose, in 2017:

The leaves are only folded on one side of the bush though...
I would think it was normal if all the leaves on the bush grew in like that, but it's only occurring on half of the bush. Which is where that other plant is growing. This made me guess that it was stealing water or nutrients from the rose bush...

How can it be normal if it's only on one side of the bush? So the other side is not normal? Sorry if this sounds dumb... I'm new.

Well, if the roots on one side were thirsty-er and the other ones were not as thirsty... if one side gets hit more strongly by the sun... etc. Also happens when underground pests damage some roots of a plant (say, on the left side) and the left part of the bush displays more signs of stress.

There's more to companion plants than just water competition. Some species have root allelochemicals to out-compete potential competitors for water but also for other nutrients. One side of the bush grows normally. The other side is just too near to the 'thing'. Their roots are fighting over a scarce resource. Your rose bush looks healthy and vigorous, however is fighting hard with the thing. As a result its metabolism is slower on that side. Plants do not have a single central pumping station called heart in humans ( or most animals), that distributes metabolic needs uniformly. So resources are not distributed patchily. At the crown area the vessels up-taking water are moved outward whilst those carrying energy move inward down. There's a crossover there but this occurrs in a ring fashion, each corresponding to the respective area downwards. So there's nothing weird of having one side of the bush faring differently from the other if there's a true obstacle in the way: the 'thing'.
I also want to Thank You! for venturing your <<if this sounds dumb... I'm new>>. actually by asking questions that others may have but are just too frightened to ask you are helping others to understand the way of things. I tip my hat to you.

The sunnier side probably matures more quickly than the shaded side. The plant puts its energy into growing the side that produces more food for the plant so it matures better. The plant will also shed leaves that do not produce food so they aren't a drain on the rest of the plant.

Whatever is the 'thing' it is a massive old stump....No wonder it is so demanding on the rose bush.(by no means use an herbicide now! because it will kill both plants)...only option left is to regularly weaken the thing by removing every new green that sprouts up. By the size of the stump, that may end up a permanent attention until in fall everything is uplifted and your rose bush is rescued.

I wanted to show you some more typical folded red new foliage . . . This is on 'Prospero'
