I have a number of dwarf dahias, all showing the same symptoms. Big, fat buds are forming but failing to open. They are turning brown at the tip and then working down the bud. Plants are in pretty much full sun until about 3pm and in shade after that.
The leaves are also being chewed, but I suspect slugs/snails as the culprit for that part. I've put 'breakfast' down for them.
Any thoughts on cause and possible solution appreciated.
