192 VEGETABLE FORCING 
being forced are wanted for propagation, as is sometimes 
the case, they must be lifted from the beds before they 
are completely exhausted, and stored in a cool, moist 
place until wanted for planting in the field or garden. 
Forcing in permanent beds.—Rhubarb may be forced 
in the beds where the plants stand by using practically 
the same methods as those used for asparagus, explained 
in Chapter XII. 
The placing of barrels over hills is a favorite practice 
among home gardeners, and this plan is used to some 
extent by commercial growers. Sometimes a shallow 
trench is dug around the 
hill so that the barrel 
will stand a few inches 
below the surface of the 
ground. No other pro- 
tection may be given the 
plant, but if rapid 
growth is desired, hot 
manure must be piled 
and packed around the 
outside of the barrel, and 
the latter covered with 
boards if maximum heat 
is required. Barrels are 
used in this way in the 
spring of the year when 
there is no further dan- 
ger of hard, freezing 
weather. The method is 
most suitable for home 
gardens.
