GROWING GRAPES IN POTS. 33 
ten, eleven, or thirteen inch ; but the ten or eleven inch 
are large enough for three or four years. 
The vine must be well established in the pot by the 
month of October, and about the end of November it 
may be cut back to, say, three feet, and tied to a stick 
fixed in the pot and may then be set in the house where 
there is but little or no fire heat, for a week or two. 
I find that if vines in pots are pruned and at once 
placed in much heat they will bleed. Of course all 
depends upon the state of the roots; if they are at all 
inan active state—which they frequently are when grown 
in pots—they will bleed if introduced into a brisk 
heat immediately after pruning. In the course of a 
fortnight from the introduction of the vines into the 
forcing house the heat may be raised ten degrees, and 
so continue till the temperature rises to 70°, where it 
may stand until the fruit shows. 
When the fruit is fairly set, a few degrees more 
may be added to the temperature to swell off the 
berries quickly. No more young wood must be allowed 
on these vines than is absolutely necessary, that is, 
only just the quantity of wood which bears the fruit, 
and as many laterals springing from the base of the 
spur as will be required for fruiting next year. If only 
one bunch is allowed on each lateral, the second bud 
from the base will be a plump one for fruiting next 
season, but some care is necessary to maintain a good 
and vigorous habit in these pot-vines by weekly 
waterings with liquid manure as soon as the fruit is 
set. The spur system of pruning must be adhered to. 
The pots should be set on beds of soil or tan and 
allowed to remain there till after fruiting, or till the
