I usually plant my hyacinths in the garden after they have finished flowering, and thety come up again in the spring. Last year i was lazy and just bunged the pot at the back of a cupboard.
I got them out of the cupboard a couple of weeks ago. They had about 1/2" of green showing. They're on a south-facing windowsill, where hyacinths usually grow like mad. There's about 10" of leaf but no sign of a bud.
What did I do wrong?
