[Arid_gardener] Re: Small Grapes

[OlinMiller]

Try using gibberellic acid.  It is a plant growth regulator used in
commercial grape production and is sometimes available in to home gardeners
at garden centers (Baker Nursery, Berridge Nursery, Gardener's World) in
diluted, small quantities.   According to an out-of-print Coop Ext Pub
(MC-59), GA is applied by a
spraying the bunches in two applications - the first application at the last
blooming stage and a 2nd one week after.

A technique called "girdling", effective on seedless varieties,  allows the
translocation of carbohydrates to the grape bunches but prevents the
translocation of carbohydrates to the root system thus making more available
for fruit growth until the girdle heals in about four weeks.  If not done 
correctly it is possible to kill the plant and is not recommended for 
backyard gardeners.
