For pot culture choose the largest or second-sized bulbs. Hyacinths are 
comparatively easy to force and respond to a rich soil. Pot singly in 
4-inch or 5-inch pots in September-October and, after watering, bury 
as is recommended for tulips and daffodils. They require eight weeks 
to be fully rooted. They should not be brought to the greenhouse before 
the flower buds are two inches long and they should be placed in a 
shady location for the first two weeks at a temperature of about 55°F. 
After this they may be set in direct light and a temperature as high 
as 70°F. will then bring them into flower in a few weeks’ time. The 
cooler they are grown, the better the flowers. For late forcing, the 
miniature Hyacinths may be potted as late as November or December.
