Lack of pollenating insects, you will need to hand pollenate with a small paint brush or Q tip

I agree with the last answer the start of the year was wet

wind so insects do not fly

however are ther any signs of stem lesions solid

swellings if so then root knot eelworm my be there

kev

thanks but can you tell me how l can hand pollenate sorry if l,m abit thick other years l have just had loads of veg and not had to worry

Take a child's paint brush dip in the pollen of the male flower and then dust the pollen into the female flowers

thank you
