I need a bit of advice concerning the aforementioned rose. It's done quite
well for a couple of years, but looks very chlorotic this summer. It has
been properly fertilized, gets enough sun, no bugs. It bloomed earlier
in the season, but isn't blooming at all now.
It is planted next to a walkway and I suspect the soil might be alkaline from rain run-off. Might a treatment or two of Miracid be called for?
