Sickly rose

I had aphids, sprayed it with bug killer last week and am wondering what's gone wrong.. I've just give it a good drink as the pot was looking bone dry but thinking it might be because it was sprayed then the sun done the damage.. or is it the bug killer..or I was too late and it was the bugs themselves?
Should I cut it back? It's out the front and looks shhh it.. was really healthy minus aphids last week

 

Ah that's not good. Aphids arw a right pain. Hopefully @wiseowl will be able to advise

 

Thanks both I'll give him/her a trim, would have thought a 40cm pot would be big enough for it.. I'll take the other bits and bobs I got in there out and replace a third of the soil while I'm at it.

Not overly gutted as it was a cheapy from Aldi and supposed to be a "blue moon", smelt lovely last year so I kept it.

 

If the weather has been anything like it has here I'd be inclined to say it just needs a good watering/soaking.
I'm watering pots that have been out all winter, and in some cases the compost has shrunk, and any water I apply just runs down the sides.
I usually dunk those ones in the pond for an hour or two.

 

Cheers Pete, yeah the soil has shrunk in most of my pots too, I normally fill a trug up and dunk them in that but I've taken them both up the plot job for tomorrow.. I went away fri-tues and have been a lazy sod since

Edit: it has been dry here too, we haven't had rain in weeks!! What's that about I'm in Wales for god's sake

 

Dare I add to Woo's post? He's the boss in the rose department!

Pull off any damaged leaves that are left behind after pruning. Also water or spray the roses when the sun isn't on them to prevent leaf scorching, evening's a good time. Spraying aphids with washing up liquid diluted in water is less harsh on plants than bug killers and works just as well.

 

Thanks Sheal I was going to do the soapy water method but had the bug killer lurking in the shed, I think it was a mixture of spraying it in the sun and not having water for so long.. oops! It's looking slightly better after that drink yesterday, I've just sprayed it with the hose and most of the crispy/aphid-y leaves fell off and it's just had another good drink. I'll prune it tomorrow

 

There's no reason why it shouldn't recover Linz. Although roses need a fair amount of attention compared to other plants they are pretty tough.

 

@Linz I've been told in another thread by Zigs that the above is not EU legal. So I think I should point this out to you before I get my wrists slapped again.
