Sir basically what i'll do is that these daffodils will remain in pots until their foliage disappears (around 2-3 months after flowering). Then these bulbs will be lifted from the pots and placed in a room having good air circulation till October. Around middle of October they are taken out outside and placed in pots at end of October.
Varieties like 'Paper White' is an early bloomer, Grand Sol D'Or could be termed as middle bloomer variety and "Tete-a-Tete" a late blooming variety. There can be various reasons for non blooming of Daffodils which have been outlined in this first page which hopefully you may find useful.
To ensure an extended display, one can even plant sequential pots of a particular variety. Some of the 'Paper white' daffodils which were planted earlier bloomed in January, some which were planted late are still blooming.
