Forcing hyacinths to bloom indoors is easy. Although hyacinths need a chilling period, keeping them in a paper bag in the fridge for 8 to 10 weeks will achieve this effect. Make sure you label the bag so your family does not mistake them for onions. When the chilling period is over, put the bulbs in glass forcing vases or wide-mouth jars with pebbles so the roots are in water and the bulbs are not. Place in indirect light. As they grow, give more light, but avoid direct sun. After flowering, plant the bulbs in the garden in late spring/early summer for flowers in the garden next spring. Hyacinths are deer resistant and will come back in the garden year after year in our area. Compared to other bulbs, hyacinth bulbs are cheap, less than two dollars for high quality, individual bulbs or six or seven dollars for a package of three. Traditionally, hyacinth vases or forcing vases are used to hold the bulbs. These are pinched vases that allow the bulbs to sit above the water. I have had mine for so many years I don’t know where they came from but you can buy them at large independent garden centers, through online garden supply stores, or sometimes as a boxed combo of bulb and vase. It is not necessary to use these; you can place the bulb on a layer of pebbles or marbles in a wide-mouthed jar, like a jam or Mason jar.
Mine will go into the fridge tonight and 10 weeks later, on January 22, (mark it on the calendar) I will take place them in the forcing vases. I look forward to enjoying the beauty and fragrance for weeks, way before my garden hyacinths bloom outside!
I force my Hyacinths the ‘other method’ by planting in soil and chilling pot and all in a dedicated refrigerator. I plant them in the garden after they bloom to bloom again the next year with those from previous years..
