Aubergine problems

they need feeding  use teaspoon ( superphosphate  ) potash per plant and 1/4 teaspooon sulphate of ammonia and water today but leave the morrows so the plants find a thirst then water every other day

Quote from Gardeners Question Time, BBC Radio4, 8 December 2002
"Question from Jill Kerrington of Barnsley: I grew aubergines for the first time this year. They did extremely well, except that they went yellow rather than purple. Why might this be, and how can I improve them?
Bob: The original aubergine, called the egg plant, has a small, white, egg-shaped fruit which is pretty miserable, just a lot of skin and seed and not much pulp: some people still sell that to unsuspecting purchasers. Aubergines do come in different colours, in India they probably have about two hundred different varieties and they’re used for almost every purpose you can imagine in Indian cooking! But the normal aubergine as we know it is the purple-skinned one. I suspect that yours were a bit cold, and they’re just turning yellow and rotting.
Pippa: But there don’t seem to be any signs of rotting, they just seem to be yellow rather than purple. Something similar happened to mine this year: it planted a good purple variety, and I ended up with a whole lot of creamy white aubergines - nothing would have induced me to buy white aubergine seeds! Unfortunately I can’t find the packet to trace back what it should have been. I agree with Bob, but mine weren’t the original egg-shaped ones, they were aubergine shaped, but disappointingly tough skinned, and I wonder if the same thing’s happened to you. "

Not much help, I now, but it happens that one just gets some wrong seed.         I once grew quite a few white beetroot amongst my red ones... :roll:
I disagree with them on the flavour of white aubergines, but mine were properly white, did not start out purple.

Thanks, MJ, I edit that :roll:  :roll:  :roll:
