In a great year the aubergines outside produce reasonably well, and the ones under glass get red spider - but it's worth buying the predator to ensure a good yield.
But in anything except a great year I have immense trouble with aubergines - the ones outside do nothing and the ones under glass don't do well enough to justify buying the predator.
This year wasn't great or poor - it was weird - but not worth spending £10 on predators - especially when my aubergine crop coincides with when they are dirt-cheap in the shops...
Of course I never have any trouble with the peppers - the red spiders don't touch them.
This year I noticed that the Orange Turkish aubergines looked a lot like peppers - smooth dark leaves with no hairs.
As the season progressed I noticed that red spider seemed to ignore them, and in the last month they have started to produce quite a good crop of golf-ball sized fruits with vertical stripes - best taken while they are green and before they go orange. Flavour is good.
I will grow more next year and less of the Euro- and African- types.
Any other experiences?
