Anyone out there an expert on growing apples? Some of our recently imported English apple trees have fruited for the first time and the fruit appears to have a strange texture in parts with almost transparent flesh, as if it were frostbitten. The first time this happened, to our Bramley seedlings, we were perplexed, but the following year all the fruit was normal. This year it has happened to our Cornish Gilliflower and Suntan fruit. Any suggestions?

Gattina There is a question and photograph posted today 19/09/11 by Member Geoffm.....is this the same problem you experienced?

Right - just shows what more reading will do - I've found out what your problem is, Gattina. It's called Apple Water Core, a disorder caused or encouraged by unsuitable cultural conditions, including excessive pruning and thinning, high temperature, high light intensity and extensive damage or removal of bark on the trunk or branches. I'd guess, in your case, it'll be the high temperature high light intensity bit that's relevant.

This isn't something I recognise - its possible this might be a problem peculiar to your region and climate.
