Hello, I have just joined this forum and would like some insight into what may be happening to my aside bed garden grown broad beans. I grow Sutton and bunyons. Every year they grow healthy with tons of flowers. I keep them well watered when podding and plenty of bumble bees have been pollinating them.
Firstly I noticed early on in growth that the very tops of the leaves have pinprick small oval shaped holes with no sign of any pest on them. Later most of the flowers just fall off leaving one or two decent pods on one of the plants. The rest just go twisted, dark and pathetically small. Also, the tops of the leaves have larger holes than before. I have no blackfly on them and cannot understand why this is happening. The last gardening forum I was contributing did not know what this was so I thought I would try people here who have perhaps more experience and knowledge.
Here are some photos including before they went downhill.
