Once the rose fully blooms, they start to fade and the petals die. The petals seems to wilt and turn inwards.
Why Do My Roses Start to Die Shortly After Blooming?
Some rose blooms last longer than others. Yellow blooms seem to be the quickest to give it up. Newly planted rosebushes will also bloom and be done pretty quickly, this is partially because the root system just is not well enough established yet to keep them going. When it is cooler out the blooms will typically last longer too, when the temps are mid 80's and up the blooms will be open and done sooner too. Just keep them fed and watered well.
