White Roses

Question

How do I prevent red spots and some brown on my roses? They bloom and within a day the spots are all over and they start to die.

Answer 1

You could have little Thrips attacking your roses, they love to attack the white rose blooms and some of the lighter yellow blooms as well. Here is a link to an article I wrote about controlling Thrips for you: https://www.gardeningknowhow.com/ornamental/flowers/roses/rose-thrips.htm
