I don't remember if it was Monty or Alan Titchmarsh but one of them said forced hyacinths never fully regenerate because the process of forcing bulbs takes a lot out of them. I'd imagine they also don't get the conditions they need to build up the energy because a lot of these bulbs naturally come from hot and dry countries like Iran and Syria. @valjones-hughes @lesliecole49 @juliesgarden
Makes sense Urzula. They don’t compare to the bulbs that grow naturally here. I remember Monty saying to treat tulips as annuals to get the best from them . @ublaszko I don’t worry too much about the hyacinths they are still a lovely pop of spring colour!
I bought some prepared hyacinths bulbs a few years ago but I planted them straight in the garden (I didn't know back then they're meant for forcing) and they are huge every year. I treat tulips as annuals as well although last year I bought some botanical tulips which are supposed to be better at naturalising. I'm waiting to see if they will flower this year.
