Hi -- I have three rose trees in front and one of them, within a week, suddenly developed almost all yellow leaves. The new growth, and new buds became almost wilted-looking but they weren't -- they were firm. The new baby growth looked burned.
I really love this tree, and I would hate to lost it. Until now, all three of them have been famous in the neighborhood for their prolific blooms. I've looked for pests, and can't seem to see any; I did fertilize about a week ago, but everything else I fertilized seems fine! Could it be the fertilizer? I've always used Miracle Gro. If that's the case, what could I do to save the rose tree?
Thank you for your time.
