Knockout Roses Not Blooming

We have four knockout rose bushes that have stopped blooming. What do we need to do to get our beautiful roses back?

Hi Pat,

The reason your knockout roses aren't blooming now has most likely to do with the weather. My knockout roses stopped blooming when temperatures hit 90+ here in Los Angeles.

If your area has had very hot weather it will slow, even stop flower production. Roses try to conserve energy by not producing flowers during severe weather. They are simply trying to survive the heat.

Your roses should start going dormant in a couple of months, so don't start feeding them at this time of the year.

I am sure next year after the annual spring pruning and their first fertilizing (only after foilage starts to emerge) they will be blooming very well again.

Happy Day
