I don't think so Hank but hopefully someone will tell you differently.

Hi Hank,

Without a photo of the apples and the tree it would be almost impossible, even then it could be difficult as there are so many varieties with about 7,000 - 8,000 different cultivars

Great help Pimpernel!

From RHS Fruit: biennial ... Some apple cultivars, are prone to biennial bearing including ‘Blenheim Orange’, ‘Bramley’s Seedling’ and ‘Laxton’s Superb’ but almost any apple or pear can fall into this pattern of cropping.

It is most likely to be initiated where trees are starved or receive insufficient moisture. This makes them unable to carry a heavy crop which in turn stimulates the production of excessive flower buds for the following year.

Biennial bearing can also be started by frost destroying the blossom one spring.

Plenty more on the RHS web site.

Thanks for the help guys.- re the apple tree. Am onto the website Pimpernel, thanks again.
Tomorrow I am leaving these shores for the Winter - in San Diego, California. But I'll keep in touch, am learning a lot here.

Lucky you Hank, have a lovely time over there...There is no escaping though...We have GoY member Delonix1 out there in San Diego. We will be expecting some Photographs and the odd Blog.

I'll wave as you fly over Arizona, too, Hank!
