Hi Derrynose, For forcing in soil, hyacinths should ideally be potted up by mid-October but you've still time.. Use ordinary potting medium and, for best effect, place bulbs close together, but not touching. The pointy tops of the bulbs should be about half an inch above the soil line. Water them thoroughly and place the pots in a cold (35 to 48 degree F), dark location for at least 13 weeks. If the bulbs start to push out of the soil during rooting, add a layer of gravel on top to weigh them down a bit, taking care not to cover the bulb's pointed nose. Keep them watered and in the dark until bulb shoots reach one inch tall. At this point, move the pot to a cool (55 degree F), bright location (a north-facing window is perfect). Soon, the shoots will turn green and buds will appear. Once in flower (about two weeks) keep the hyacinths cool and well watered. cheers Pendelli
