Wilting rose bush. What to do?
Not sure where on earth you live?? But in the USA you can budge to a grocery store where they trade flowers or a discount store. They sell them outstandingly cheap-- about $10.00. If you hold an Aldi close by, I would check them out. Extremely cheap!!!
If you order them from a florist expect to take-home pay $50.00-$75.00+ for a dozen.
