Im am having a problem with the leaves on my roses. They are turning a pale yellow and brown and I am not sure why.

Would anyone have an idea as to how to prevent or combat this?

Thank you so very much

I think your roses are probably hungry and also suffering from a bit of blackspot ( and possibly red spider mite - difficult to identify from photo)

Remove the affected foliage and gather up any fallen leaves to prevent further spread of infection. Feed with a high potash, proprietary rose food, and if you're not an organic gardener spray with 'Rose Clear' (or similar) to kill any pests and protect against fungal infection.

Make sure plants are kept well watered, roses are thirsty. Lack of moisture can weaken them.
Hope this helps. Crossing Fingers!

@RainerSchleicher Welcome to NGA and to the Rose Forum .. Smiling

You don't say where you are growing your roses ... you can update your profile any time. The only reason I am bringing that up is that it gives is an idea of the kind of climate you have for your roses.

@pjnew is right on about this rose needing more water. The brown leaf tip in the first photo is an indicator of water stress.

Water stress can be caused by under watering, root competition, or by fast drainage. If the problem is caused by fast drainage, that means the water you have applied to the plant is moving through the root zone too fast for the plant to take up the moisture it needs.

Not all roses have the same water needs. Some roses are more thirsty than others, so you need to adjust your watering accordingly.

There may be other issues, but water stress appears to be the obvious problem in your photos.

I hope this helps.
I'd rather weed than dust ... the weeds stay gone longer.
