Aubergines

Folks,

I am determined to succeed with Aubergines this year.  I currently have six plants but they got attacked by greenfly.  I cleaned off the greenfly and gave them a feed of half strength tomato feed and I can now see some tiny new leaves starting to sprout down the stems (if these manage to come through they should be nice and bushy.  I can just see the roots in the holes at the bottom of the pots and I was going to pot them on into bigger pots but should I hold on until they recover a bit?
