My rose leaves are yellow and brown
Hello,
I have some rose bushes which I inherited from a previous owner of my house. There are quite a few bushes, and I don't know that much about roses other than that I've been learning to prune and care for them. I know that four are hybrid tea roses which are about six feet or more high (two red, two white -- the red are "Taboo" variety according to the tag I found buried). Roses are heavy blooming in my zone 9b, really year-round here in Sonoma County, CA, and we also have heavy clay soil which drains pretty well because of a bit of sandiness to it. They are mulched with new wood chips and watered in the morning usually, or sometimes in the early evening. They are in half-day afternoon sun in the summer due to shady deciduous trees.
Anyways, I have been battling two different leaf issues all summer and keep cutting the leaves off. These roses are nice up top where I've dead-headed them (which causes them to really grow back heavily with buds, in a few weeks and with nice, new leaves which are fine). But no matter how many of these bottom leaves I cut, I have two different looking problems on the lower leaves, and I wonder if someone who knows can help me out towards fixing whatever it is.
So I have included three photos. One is the nice looking upper growth where I have deadheaded (or pruned? Unsure, I am deadheading where you would prune a rose, at the first five-leaf outer-facing bud below the dead flower) with all the healthy leaves. The second is yellow and brown tips which are mysterious to me. The third is some kind of blotchy yellow leaves, maybe it was rose rust but there's nothing visible on them now.
What's wrong with these if you know? Thank you!
Exhibit A: Pretty healthy regrowth from deadheading these a lot (but some yellow leaves still and some spots in the lower right). So the upper parts of all my bushes mainly look like this.
Exhibit B: I'm most worried about this, because it's really getting worse, and I don't know what it is. I keep cutting off a lot of the leaves because of it.
Exhibit C: I suspect this may have been rose rust but is gone now and just left discolored leaves? But the tips are also brown, and there is zero rust that I can see on them now, although it's summer so it's not good conditions for rust -- my area has low humidity and almost no rain until winter.
Super appreciated! I never took care of rose bushes before, so I'm on a learning curve. I have five others which are their own problem, but I'll leave those for another post.

Yellow and brown leaves on my aspen tree
Comments (15)I agree that the natural distribution of Populus tremuloides includes some parts of OR. However, provenance is important for success of many trees. I suspect this variety is the same, and around here we use that var for better success in the lower elevations of the Front Range, as the trees from the mountains can be depended on to die quickly down here because they are not adapted to this elevation or climate. IIRC that var is selected for alkaline soil and grassland-steppe environments, having come from a relict stand in western NE. The leaf edges and mottling look to me to be maladaptation to something in the water and a deficiency-toxicity in the soil, where bboy and I agree. I'd expect better success on the other side of the Cascades, esp out on the WA Palouse, up near the Blues, or some of the Basin and Range. Dan...See Moremini rose bushes with yellow/brown leaves
Comments (2)Could be that they needed to be hardened off. They were grown in a greenhouse, and need time to get used to being outside in direct sunlight. In the future, before you plant them, gradually expose them to sunlight over a week or two. You can tell pretty quickly if the leaves are starting to burn. If the canes are still green, they should be fine....See MoreMy magnificent Spider Plant is sick, yellowing then brown leaves!!
Comments (24)I need help. My momma spiderplant loves direct summer sunlight. I know its weird but she got three times bigger this summer and so so green. She's about 9 years old. I have growing babies also from her. But I brought her in like I always do for winter and put them all under my grow bulb for six hours daily then rest. I put her in a nice large pot with lots of room. Her roots were so congested. But I didnt break up the root base. I never have before either. But now she is sick! First her leaves turned brown and cracked in half. Now they are turning yellow so fast half of her is gone. And bad burns on tips. I only give her purified water now. In summer it was tap and no issues! I fed her a fertilizer stick in her new pot. Now my medium sized babies are yellowing and burning on tips. I changed their soil to an all purpose soil is the only difference other than bringing them in. I didnt change the pot on the medium babies. I've never seen her sick like this. Please tell me what to do! Help!!...See MoreThe top of my fiddle leaf leaves are turning yellow/brown
