Osteospurmum buds not opening

I have 2 osteospurmum in tubs in sunny spot, they were full of flowers when I bought them and deadheaded them as soon as the flowers died.I was happy to see lots more flower buds coming but now instead of opening they seem to have dried up and gone brown. I have watered them regularly and the plants look OK, just no flowers, what went wrong? Thanks

It's not every day I find I've been too kind to something, wonder if they would be better in the garden rather than a tub (which contains compost)
i have the same issue but with various plants
is this what u mean? = http://www.gardenersworld.com/forum/problem-solving/various-problems--pics-included/765169.html
hey i thought may like to know - i think it was something to do with too much nutrients in the soil, as now mine have started to flower again properly (on all the effected plants) so i think the excess has now been used up
hope that makes sense
how are your plants doing ?
bad news - ive worked out its honey fungus.......
google it..
