hi

wondering if anyone could help with my problem

i have 2 tubs of lily citronella strain that are about a metre high and just coming into flower bud. the leavs on some lilies are rotting off starting about a quarter of the way up (leaving the older leavs lower down) . the rot often starts at the leaf tip, but sometimes from spots on the leaf. ive sprayed with a systemic fungicide, and its been very wet recently here in the uk.

another area of citronella strain is unaffected, and other lilies in the same pot or close bye are also uneffected, it appears to be attacking only the citronella strain.

any ideas?... thanks.
