Iceberg Roses Color Change

by Leslie Mowers

QUESTION: I have approximately 90 Iceberg Roses.

This year we switched from chemical fertilizer to all organic fertilizer.

Compost was also added for the first time.

The majority of the Iceberg roses get four to six hours of sun, some receive more sun.

The roses are now disease free due to extra care.

My question is: this year all the Iceberg roses acquired a pink tinge as summer approached.

I don't know if it is from the fertilizer (I doubt) or heat or some other cause.

I have seen other Icebergs doing the same thing.

Thank you in advance for your assistance.

Best regards,
Leslie Mowers

ANSWER Hi Leslie! I have a bunch of Iceberg roses, here in Los Angeles.

The Icebergs pure white flowers willl have occasional pink flushes in the bud stage, especially in early spring and fall, when nights are cold and damp.

Some pink spotting will also appear in the petals caused by dewdrops, or rain, that remain overnight and then being color activated by the morning sunshine.

It's totally weather activated, and it's not because of your new fertilizer.

There is nothing we can do about it, short of drying off the petals before the sun comes out.

Best Regards,
