Re: @Corinne
That's been suggested but apparently not the problem, if anything I didn't water plants enough.
Tried an experiment with a neighbour at a previous house (same row of houses), she checked my soil was the same as hers, both gardens faced the same way, planted the same seeds/seedlings, both let nature take it's course i.e. they were watered when it rained, hers thrived mine died. Though I did have a rampant golden globe buddleia she was jealous of, couldn't keep the damned thing under control despite hacking it practically down to the ground at the time of year they tell you NOT to because that may kill them!
A friend used to tend my flowers & shrubs for me, even if I did anything to them under her strict instructions with her watching they would die whereas the ones next to them that she tended were fine. plants just don't like me :(
