Weed killer on roses

It might help, although the systemic nature of Roundup means that it may already have penetrated the roses' tissues. I do wish you luck and hope that they recover.

Poor roses! It pays to read the labels, especially when using poison.

I think I'd leave well alone and see what happens. If some of the stems/branches start to die I'd cut them off to prevent rotting but otherwise give the plant a chance to recover (Hope!!) without stressing it more by extreme pruning. Perhaps a gentle nitrogen feed to help them along .. ?

This question often comes up - people have accidentally sprayed weed killer on a plant they want to keep - and the answer is simple and very effective.

Usually weed killer is sprayed in the dry so it's very easy to ID which plants have been affected. Remove those leaves IMMEDIATELY and then simply empty a watering can with a rose head over the plant. This way, your plant will not suffer one bit.

If you waited to post the question here it's far too late and with roundup it takes 2-3 weeks to see any results - which is one reason not to use it.

How soon did the rain appear? Within 5 minutes, your plant might be lucky.

If it's a big established rose like a scrambler it will almost certainly 'shake off' roundup if it rained soon after.
