Pollinizing Plums

Fruit Growing
How many rows of Robe de Sergeant prune trees should be alternated with
the French prune (the common dried prune of commerce) to insure perfect
fertilization of the blossoms?
The French prune is self-fertile; that is, it does not require the
presence of other plum species for pollination of the blossoms. It is
the Robe de Sergeant prune which is defective in pollination and which
is presumably assisted by proximity to the French prune. If you wish to
grow Robe de Sergeant prunes your question of interplanting would be
pertinent, but if you desire only to grow French prunes you need not
plant the Robe de Sergeant at all.
