Thanks both for the suggestions. I'm fertilizing with a liquid feed,
the label on the bottle suggests twice a month in the growing season,
and once a month in the winter. I think I'll halve the amount in the
growing season and not fertilize at all in the winter, and see what
happens.
This weekend, I'll give the soil a real good soaking to try to get rid
of the built up salts. I'll report back here in a couple of weeks if
there's any change.
Loki - do you get much fruit? At the moment, I have 0 flowers.
Thanks again,
Mike
