cut the dead flowers off [deadheading], give them a general feed and leave the leaves for about 6 weeks before you cut them off.

nip the heads off so they don't make seed,leave them for about 3-6weeks until the leaves go yellow them cut the leaves down,the bulb needs the goodness from the leaves to make next years flowers,i sometimes give mine afeed as well,it all helps.

we typed together then seaburngirl.

Six weeks Plantmaiden minimum, feed with half strength liquid tomato food during this time to nourish the bulb for next year. Something that many folk do not realise is that next years flower develops in the bulb in the weeks after the bulb has flowered this year. If you like think of it in the terms of a human females gestation… takes 9 months from impregnation to birth…

my normal ones take about 6 but my little ones die down quicker,think it depends on the weather as well,but yes i agree with you.

Even or miniature narcissus take about 6 weeks for the leaves to die back.
