Chlorosis in Rose

Anyone have tips on dealing with severe chlorosis due to lime leaching? 

I had some fence replaced last year and the rose is just next to it. I noticed the rose starting to struggle badly late last year with the foliage showing chlorosis.  I tried the usual things of adding compost, adding Iron as sulphate.  A few months ago, I added a cup of sulphur chips to the soil and have been adding tea leaves to try to bring the pH down. 

I used one of those cheap stick in the soil pH meters and it reads half way between 7 and 8. Following this, I added more sulphur. 

The new growth for this year is really chlorotic. In a panic mode I have added a few teaspoon of Fe DTPA. It's been just over a week. 

I'm mulling over the possibility of other nutrient deficiencies.  Unfortunately, i cannot move the rose. 


Anyone know how long the lime leaching from concrete will happen?  Any suggestion from the lovely people on this forum.

Time to try one from your Granddad's time, Epsom salts was always the old standby for everything rose related

I've heard of Epsom salts in the garden.

Just started to look it up. Interesting.

I used to use soot for some plants. Another old idea that works.

I had paving laid last year and was concerned. Some Hidcote Lavender wasn't happy at all as some other perennials but this year they are doing fine.

I did remove any (and there was a lot) of concrete bits laying in the soil. Took ages.

How close to the concrete is the rose sitting?

I did add some Epsom salt a while back, I'll add some tomorrow.  
Is there any point in adding some weak acid to the soil as a temporary fix to neutralise the lime?
