<pre>Brian et. al. - About a dozen trees out of this orchard have been
transplanted to a nearby area on the same farm. Many, but not all, of these
trees have a good crop of small Picholine looking olives. Does anyone know
if Picholine needs to be cross fertilized, and if so what are good
pollinators for Picholine?

Thanks,

Alan Friedman

<pre>Alfredo,

One thing you should look at is pollination. If they are one variety
pollination will be poor - like terrible. It does seem strange they have
no olives in spite of their negelect. It could be an "off year" but it
sounds more serious than that. Generally the English speaking olive
writers play down pollination - for example the Olive Production Manual
from the University of California. The totally misleading statement that
olives are mostly self fertile is repeated again and again as one author
copies the mistakes of the last.

Our book (Discovering oil) has a lot on recuperating old olive
trees. Naturally I would like you to buy a copy but more realistically
it is in the library of the NY Botanic Gardens in the Bronx. If you are
in NY for some other business you can look it up.

Cheers Brian Chatterton.
