Hi,
I'm having a little trouble with my knockout roses. I was told I didn't have to deadhead them. They bloomed very well in June then ,they had very few blooms in July. Now they look like this. What would cause this? Do they look normal? I love these type of roses,but I want to be sure I am properly taking care of them.

I just got home from a seminar on Earthkind roses. Knockout should need only adequate water (preferably applied at soil level) and either several inches of mulch (which slowly breaks down into fertilizer) or a couple of fertilizations each growing season. If it develops any black spot the plant itself will not be harmed, although it is unsightly. Most roses go in and out of bloom during the spring, summer and fall. Yours may be "resting." Deadheading this rose is cosmetic; it won't spur reblooming.
Knock Out was first introduced in 2000 and hailed a "breakthrough shrub rose" by the All-American Rose Selections because of its exceptional disease resistance and hardiness. It was one of three roses to win the prestigious AARS award for outstanding garden performance in 2000.
Hardiness: Zones 4 - 9
Exposure: Full sun
Size: Height 4 feet tall, 3 feet wide
Bloom Time: Spring to frost.
Care: Use drip or soaker hose irrigation.
THANKS dp72 ,
That was great info and very comforting for me. The people here are so kind to take the time to help others.
I appreciate you all.

How long have they been in the ground? After last year's drought lots of plants are taking it easy this year, especially the ones planted in the past three years. Overall your roses look healthy so I wouldn't worry about them too much. If you haven't feed them in awhile I'd go ahead and give them a granular rose food. Also, next year in late winter, you could prune them back a little to make them fill in better.
