My friend and I are having problems with our raspberries the leaves on her's are going yellow and hardly any fruit and I have had some fruit but I'm finding some are white/red. I can send you a picture of them if it would help.
Thank you

A picture would help, but the leaves do go yellow on the old canes as they fruit, they are putting all the energy in to the fruit. You cut those canes out after fruiting, down to the ground. The new canes should be a healthy looking green.
Loads of food and water - they love it at this time of year.

I, sorry about the delay in sending the photos of the raspberries I've also included a leaf off our Pear tree we are having yellow spots on them and never had any fruit in three years.
The pear is suffering from pear rust - remove every affected leaf and either burn or put in domestic waste. Also pick up any fallen leaves and do the same. This year has been particularly bad for pear rust and all of my trees have been affected to some extent. The disease has two hosts and overwinters on Junipers, so if there are any of those in your or neighbouring gardens, it'll be back next year.
The raspberry has 'white drupelet disorder' which is thought to be caused by too much sun (UV damage - a bit like sunburn to us) on the fruit, so it could be the position is a little too open and sunny for them (raspberries can take a fair amount of shade and still crop well.) I grow my rows orientated north-south which helps as the canes then shade each other to some extent.
Thank you so much for the information you have given me it's been a big help, I will be passing this round to other allotment holders.
