Chlorosis on roses

HELP! needed please, I have noticed two of my roses have chlorosis what is the best cure? They are not planted near one another) tia

 

Hello @Meomye , usually it’s a sign of some sort of nutrient deficiency so a feed should help. Are your roses in pots? I only ask as they are quite hungry plants so if kept in pots a regular feed will help.

 

@Butterfly6, thanks for reply, no, not in pots, in the garden soil. Other roses seem fine.

 

There are a few possibilities and a photo or two would help us come up with some suggestions.

If the veins in the leaves remain green, but the rest of the leaf is yellow then Magnesium and/or iron deficiency is likely - one dose of sequestrene would sort that out.
If the leaves are completely yellow then it may be the soil is too wet and that may disrupt the take up of nitrogen and cause yellowing.
A lack of nitrogen in the soil - but unlikely.

Seaweed extract is a great tonic for all plants.
It is not a complete fertilizer, but does contain all the vital micronutrients that plants must have and are possibly missing from your soil.

 

@Pete8, thank you for your reply, after some research, I am pretty sure it is chlorosis although I have no idea how it has happened as my other roses seem fine and I have done all the usual precautions building up to summer with regard to mulching feeding etc, so it looks like they need iron/magnesium. What steps do I need to take next? tia

 

Something that contains sequestered iron with magnesium would be ideal such as-

Any similar product that contains the same would be fine.
You should only need to apply it once as a soil drench.

Alternatively, seaweed extract also contains iron, magnesium etc etc etc.
A foliar spray (done on a cloudy day when no rain is forecast) will be absorbed very quickly.
But used as a soil drench is fine too.

Hope it helps

 

Thanks @Pete8, that is very helpful.
