How often and when should a rose in a pot be fed? This is Iceberg. I think by the size it has got to this spring the roots must have found their way down through the holes in the bottom of the pot and into the ground. I know roses in pots need feeding more often than when planted in a bed, I believe three times per season instead of two, but when best? I gave it 20 grams of powdered fertilizer at the end of March. When should the second feed be? And when should the third and final? Advice appreciated.
