Just planted out some hyacinth bulbs, only been out just over a week and look like they are about to flower,apparently you only get about three weeks of flowering then its time to deadhead them ready for next year,after deadheading would it be ok to lift them and store them somewhere ready for next year or is there much chance of them flowering again (didnt realise you only get about three weeks of flowering) as where they are i could do with something that will flower most of the summer.......any advice appreciated.
