my first time with aubergines too. Have six plants in two growbags in greenhouse, along with chillies and peppers. Everything else is in the polytunnel (or outside) as I wanted to put things in the greenhouse that would do well in a warm 'climate' so I have been keeping the door closed but vents open (wide in warmer weather and even opening the door some days). Four of the six plants are doing brilliantly with 4 fruts on one plant and two or three on most of the others. One of two plants still only have flowers though. The fruits are about large apple size now (but not the same shape, obviously!). My question for any experts is, should I pick them quite small - is it too optimistic to hope they get to 'shop-type size' and if I wait for big 'ens am I in danger of losing them? (Chillies and peppers also doing well, so lots of chilie jelly again this year, methinks!).
