can any one till me wot red tint on the leaf is thanks

[Yorkie]

I don't know, but the yellow colour on the leaf suggests to me that the raspberry isn't getting all the nutrients it needs.

Have you put any fertiliser down?

Also, have you used any weedkiller in the area?

[Wombat18]

I have had the same thing with mine.  I think yellow leaves are a sign of nitrogen deficiency.  A scattering of sulphate of ammonia or pelleted chicken manure will give your plants a quick fix, and a top dressing of well rotted compost will sort them out in the longer term.

is sulphate of potash o k

is sulphate of potash o k

There is no nitrogen in suphate of potatsh; give a liquid feed like Miracle Grow or Phostrogen for a quick boost then a general purpose fertiliser like Growmore or pelleted chicken manure for a longer-term feed (assuming it ever rains to wash it in, that is!!)

any one no wot this is is it to much water i gave them sum sulphate of potash got it from b an q  they was the first lef that can out on them that's looking bad any one no wot it is thanks

[Yorkie]

When did you put the sulphate of potash on?  I'd leave it for 2-3 weeks after applying the fertiliser to see whether there's an improvement.

If it isn't a lack of other nutrients, it may be a virus which isn't good news - but wait to see whether the plant picks up first.

about 3 to 4 days

[fatcat1955]

Have you been using a potash fertilizer? if so this prevents the plants taking up magnesium. If this is the case spray with epsom salts.

[mdjlucan]

any one no if this is mosaic

[mumofstig]

can't really tell, have the yields started to go down or is the growth stunted?
These will also help confirm a virus.

[Yorkie]

I have merged your 3 raspberry threads into one, so that everyone can follow the previous advice.

JayG suggested that sulphate of potash probably wasn't the right fertiliser - did you apply growmore or chicken poo as suggested?

Fatcat also suggested that you try spraying wtih epsom salts - have you tried that yet?

It might be a mosaic virus but without eliminating the other nutrient issues, and answering Mumofstig's other questions, we can't tell.

[mdjlucan]

sorry first time growing raspberries wot do you men yields growing down

[Yorkie]

If this is your first season with them, you won't be able to answer that question.  It means 'are you getting fewer raspberries each season'?

[mdjlucan]

all so no Epsom solts yet how do you make it up all so going to feed them with j Arthur bowers mult p fruit and veg food mric grow
