Pests & diseases in my garden

Can anyone tell me if we have raspberry sawfly in the UK?  My raspberry leaves are being stripped. I can't see any caterpillars on the leaves, but we had rose sawfly last year and the leaves were stripped in the same way.


Also I have a hammamelis which is looking very sick.  The leaves are losing their green, and shrivelling up.  It's in a pot of ericaceous compost, and I have fed it 3 times with sequestered seaweed feed, but it still looks very poorly.  Is there anything else that might help?


  • What spray can I use on runner beans to kill black fly and to prevent them returning, without poisoning ourselves when we come to eat them ? My beans are smothered at the moment. Have tried 'grey' water, waiting results.
