Caring for roses in hot weather

I checked the weather projections and learned that temperatures for the next 7-10 days for SoCal are for mid-90s. Add to that higher than normal humidity due to warmer ocean water temperatures. All in all, temperatures are trending higher in the last five years. I advise you to thoroughly hydrate your roses over the next few days to prepare them for the high temps coming, and continue to do so until cooler weather.

If you're using drip irrigation, run your system in the early morning or evening to give your roses the opportunity to thoroughly hydrate...
