Hello from the southern hemisphere, my daffs are doing similar things. I have a group that I let grow in a multiplication nursery bed for some years. They are reasonably well spaced and yet only a few flowered . They are in a very sunny spot and fairly well protected. They have normal size leaves but no flower buds. Another group was planted the same fall ( 4 years ago) on a very sunny slope, naturalized among grasses. Both never received more fertilizer than initially: a good quantity of our own compost. This second group ( presumably in worse condition than the former) flowered profusely. The cultivars of the flowered ones are different. Perhaps that may explain it. For those who have longer a further knowledge in growing daffs, what would be the reasonable time to let daffs undisturbed in the ground, before lifting them and starting all over again? If fertilizing could be the cause, what would you use, something organic around the clumps after flowering? It doesnt make any sense to me in adding fertilizer once the leaves start yellowing because nutrient uptake is an active ( photosynthetic wise) metabolic process. The food after the yellowing starts, is no longer available to the plant that is moving towards dormancy. Would you then fertilize just after flowering? Would you instead add a general 15-15-15 fertlizer around the clumps? My daffs are now starting to fade off and I should be doing something during the next week or so,. They have all of November and by the beginning of December they start to yellow . By Christmas they are completely brown ready to be lifted or top planted with anuals. Unfortunately, with the exception of King Alfred, all the rest of cvs. are from unkown sources ( namewise). Thanks to all. Arturo
