Help with roses

ezra_

Hello,

I'm wondering if we are too late with our roses.

We bought them a couple of months ago and all have flowered and been deadheaded bar one.

However;

One of them has started to have its leaves turn sickly yellow


The second is turning red


The third has flowers, but the leaves don't look great


The last is been eaten (all of them seem to be food for something).


Is this normal or a problem? is there anything that we can do?

There are many reasons for yellowing leaves on roses. Shade can cause it. Water at the base in bright sunlight can also cause reflected light to scorch them. Over fertilising also lead to yellow leaves.

All that said, they will be fine next year if you remove the cause.

Thanks!
We aren't fertilising them, and we haven't had that much sun of late.

Any other ideas?

Are the red leaves / eaten leaves something to worry about?

Actually, it look like they all have black spot fungus.



I will do the following:

Black spot is there, as well. You can spray for it but it's not usually necessary. Just gather up any infested leaves and dispose of them properly.

Thanks guys.

Two of them were pretty badly hit and got totally denuded of leaves (the garden person says that is ok).

The other two weren't that bad, and we removed the ones with signs of them and sprayed them (more of a test to see the effect).

The garden centre lady said that this isn't something that is fatal to the plants and shouldn't have an effect on them next year?

Not at all. Roses will be green and flowering until December if the weather suits.
