Rose leaves curling, turning brown, and half eaten.
Comments (1)If you unfurl the leaves, you may find webbing, or leaf roller . It protects itself and feeds on the leaves. I think it may form a caterpillar. If I find them, I squish the leaves and remove them. I hope you don't get more infestation. The few I have found on my roses, have not proliferated much. But of course, I do not know about your zone....See MoreRose Leaves Turning Brown
Comments (4)Fertilizer burn starts with brown, dry edges, often in a pattern of small circles against the edge. The treatment is flushing the soil with two inches of water. Just a guess, obviously....See MoreHeritage rose leaves turning brown
Comments (11)To me, it looks like it suffered a heavy rose slug attack a few weeks ago, but the rose slugs were destroyed by visiting good predator bugs and the bush started pushing out good leaves with no damage (the ones on the "outside"). Check the backs of the damaged leaves and see if you can detect any tiny, teeny green "worms"--if so, they are the rose slugs and should be quished, or if you are squeamish, tossed into the yard. They probably won't find their way back. Since a few of the outer leaves also look like they may have some damage on them, it is likely at least a couple rose slugs are still hanging around. If there are no rose slugs (and it only takes a couple to do a lot of damage), then your problem is already solved. In which case, you might spruce up the rose's appearance a bit by pulling off the most damages leaves, but if there is still some green on them, perhaps leave them since that means they are still producing food for the plant. But some of the damaged leaves could be removed. Usually no spraying is needed. This only happens (sometimes) on some of my spring blooming roses. Between manual inspection procedures and, a week or two later, the arrival of the "good" predator bugs, the whole episode passes rather quickly (until next spring).

Comments (21)Kelly: My order from RU also comes this week: Poisedon, Munstead Wood, Dee-lish, and Lady of Shalott. Granular gypsum is sold cheaper at feed-store or at Menards at $4.59 for 25 lb. bag. Despite being next to a limestone quarry, my soil-test came back barely adequate in calcium , due to calcium bind up with magnesium and phosphorus at high pH. Gypsum made a BIG DIFFERENCE in my tomato. For many years my cherry tomato would crack in rain, then it gets mushy & watery at hot temp. After using gypsum, my cherry-tomato are firm & crunchy & thicker skin and no longer crack with heavy rain. If the bottom of the hole is too hard to dig, I put gypsum, pour in some water, take a break. When I come back, the 17% sulfur in the gypsum soften the hard-clay at bottom, so I can dig deeper for drainage....See MorePam Honeycutt
