When I bought my house, I became the owner of a bunch of rose bushes as well. Roses look nice. Roses also require direct care to do well. This puts me in an interesting position. On one hand, I am not terribly interested in expending effort to make plants grow better. On the other, they only require about half an hour of care a week, now that I've fixed the most glaring problems with them. Since they certainly look nicer than either dead rose bushes or no bushes at all would look, and it would be a pity to just let them die, I take care of them. And, I suppose it is rewarding on some level to see a bunch of blooming roses and know that you are partially responsible for making that happen. But, all things considered, I'd really have preferred something that looks perhaps not quite as nice, but requires no effort.
Perhaps I'll change my mind next time I realize that I've got to trim off some of the activities that take up so much of my time on a weekly basis if I'm ever going to get anything done, which seems to happen somewhat regularly. Maybe I can donate my roses to a neighbor; they'd still be around to make things look nice, but I could reap the myriad benefits of laziness.
