which deficiency is this please?

have been reading up and in my very humble opinion it may be iron or maybe manganese deficiency? or not........

My garden is very new. The rose has only been there for 3 months and is already lacing in something. There were no plants there before except grass. I dug out loads of clay and replaced with topsoil and sharp sand. Maybe I was too heavy on the sand?

I recently started feeding with doff rose feed in a liquid form. it says to feed every two weeks which i have done 3 times so far.

the rose itself is very healthy with loads of gorgeous flowers-gertrude jeykll- but its obviously not totally happy. below hopefully is a photo.

if anyone can point me in the right direction my roses will be very happy!

 

If it is showing on the older leaves first then it probably is Magnesium deficiency. You may have been too heavy on the sand as they are prone to this on sandy soils. It should improve with a rose feed though it might be an idea to add some organic matter, but I am no rose expert and I am sure someone on here who is can help more. It does say that this rose prefers a sunny site too.

 

The problem with a liquid feed is it gets washed through the soil when watering the plants. I garden on sandy soil and haven't seen this problem on my roses. As my roses start to leaf up in spring I scatter chicken manure pellets around them and just ease them under the soil with a fork or rake. When flower buds appear I then use blood, fish and bone around each rose. Later, towards the end of July they will have their third and last feed of the year, again blood, fish and bone.

 

One book of mine does recommend using a foliar feed which would prevent it leaching away in the soil.

 

thank you all so much. i did mix all the new soil and sand with the old but was heavy on the sand! i also did mix some of the rose soil it came with. I have fed it so think i will just wait and see what happens over the next few weeks. Its a lovely rose and even though its new have had about 12 roses on it so it must be fairly ok.

 

its a very late love but one that is growing stronger.........
