I have a mini rose bush in a pot. They are pink. I use miracle grow once a week. They are blooming nicely and regularly. The bloom gets full size, then after a couple of days, the color fades. I live in South Texas, and they get partial sun, but direct sun and heat. What is going on, how do I fix it.
Thanks!!!

Pigments in roses are UV sensitive especially yellow pigments but most colors shift with time and continued exposure.
Some red or pink roses change color when exposed to the sun, they fade 'blue' because some of their pigmenting containing yellow bleached out leaving a paler, bluer or purpled, pale appearance.
Strong colors in complex combinations show the greatest variability as tiny changes in one of the rose's pigments can shift the perceived color quite a bit. Roses with pink ,cerise, rose, or crimson tend to be the most stable but it depends on the specific pigments.
Another impact can come from the soil. Certain minerals will affect color shifts if they are not present. Some people claim alfalfa pellets have helped roses achieve stronger colors but I do not know how they measured this or if it was what they perceived.
Cooler or hotter temperatures can also cause changes in the pigments the plant produces. Have you had strong temperature changes from the day to night?

Color changing has been used to great effect in some roses producing staged color shifts in roses like Joseph Coat, Mutabilis, Masquerade, Double Delight, or Flutterby that begin yellow and shift to cerise tones. This is called phototropism.

depends on the species, some fade in the sun, I have one that faded form a dark pink to a lighter shade, I think it is pretty. the fading is genetic response to sun. nothing you can do except get another rose kind that doesn't fade. I have the prince, austin rose and it gets darker as it ages. quite stunning. it starts off a medium dark purplish to a darker almost blackish purple red.

Just like everything color fades when exposed to the sun, also the blooms could be dying. Maybe they are not getting enough sun my flower plant faded the blooms because it did not get enough sun.

Roses naturally fade before they die. Make sure you are not fertilizing them when they are in bloom, only when you want them to bloom.
