Forcing
The acceleration of a plant’s vegetative growth, flowering or fruiting, using the manipulation of temperature and light to ‘force’ the production of the growth desired. Rhubarb, chicory and hyacinths are commonly forced. Commercial forcing is carried out in specially designed greenhouses or sheds, often with additional bottom heat. In the domestic garden forcing is usually improvised in greenhouses and frames, or achieved with the use of forcing pots to cover individual plants.
