Several years ago, my husband bought me two climbing roses; one yellow, one red.
Mr. Yellow Rose never did very much, and, sadly, passed away after a valiant two-year struggle to live. Mr. Red Rose managed to hang in there, but never did very much.
My husband has been threatening to yank out Mr. Red Rose because I'd get one, maybe two blooms a year. Whereas my heirloom rosebush explodes into bloom in late June and keeps blooming (although not quite as enthusiastically) all summer long. In contrast, Mr. Red Rose was a real non-performer.
This year looks to be different. After an attack of aphids, I was afraid I wouldn't get any blooms. But, Mr. Rose has been diligent and rewarded me with the first rose of the season. And now there's a second one about to bloom. Not only that, but there are six more buds forming.
Maybe I should threaten to yank all the non-performers. That might give them incentive to bloom, too.
