JFK Rose

Reply Contact

My white rose petals turn light brown around the edges. This brown is there as the bud breaks open and when in full bloom. What is this disease and the cure?

Thanks,

Carol in Maryland

Thrips to be the problem. Thrips are tiny, slender, dark brown or black, sucking insects that damage and destroy opening rose buds turning them brown and leaving them only partially opened. They also feed on the upper surface of the leaf. They can be difficult to see outdoors. If you think that your rose may have thrips, take a cutting inside and shake it over white paper to see if any fall out. Look for a brownish black insect with a narrow body up to 1/16 inch long. They thrive in hot, dry conditions. Regularly watering your roses and spraying with an insecticide or simply cutting off the affected rose or leaf should do the job and destroy infested buds and flowers.

Carol,

Lovely rose, but NOT AN ENGLISH! That's a hybrid tea!

I'm down here in zone 8, and I cannot begin to tell you the problems one would have with JFK. It's the Edgar Winter of the rose world! You may be experiencing thrips. A good systemic insecticide is good for that, or beneficial insects (earwigs or mantids) if you're organic.
