Monday and Tuesday (4/8 & 4/9) were unpleasantly windy!  The result of all those limbs being whipped around and rubbing together can be seen on the ground.  Some of the lost nuts were loosely attached and would have been lost during the "June Drop" (which usually occurs in May!), but there are good nuts lost as well. 

Looking out my (mobile) office window was beautiful today. Quintessential bucolic! 

thunder storms

We have had a few days over the past week with showers, maybe 3/4 of an inch accumulation in some places, less in most.  Last weekend we had a spectacular light show as thunderstorms moved through.  Thunder showers bring free Nitrogen as the lightning fixes atmospheric N into plant useable forms, but it also brings the risk of hail. (No hail damage yet this year)

Crop sizing

The almonds are getting big enough to be clearly visible from a distance. We have had mostly sunny days which will help the trees hold more nuts. This is a fifth leaf Nonpareil tree.

Every other week, The Old Mill Cafe in Modesto is the site of an early morning pest management discussion hosted by our local Farm Advisor, Roger Duncan.  Farm Advisors work for the University of California Extension Service.  Their mission is information and technology transfer.  The system has been very effective in keeping California growers aware of the most current research and knowledge base.

Pruning walnuts (Tulare variety) after their second year.  The pruning appears severe, but if the limbs are left too long, they will bend from their own weight and the tree will be misshaped.  By building a strong core structure, theses trees can hold a big crop in another couple of years.

 I am amazed every year by how rapidly the nuts begin to grow after the ovary is fertilized.  The bees and pollen have done their job so it's "off to the races".

In this picture we have blossoms still blooming, blossoms with fallen petals, nutlets just breaking their jackets (the calyx), and nuts from which the jacket has fallen.
Just after jacket-split is the most frost sensitive time for the nutlet.

PETAL FALL !

Our benchmark rows. The Nonpareil are well into petal fall and the Wood Colony (with the flag) are shortly behind.

On the other side of the Nonpareil row, the Monterey still have a lot of bloom time left.

It is not obvious from these pictures but we are irrigating.

We still need to chop up the mummies which have been swept to the center of the middles.

Bloom is starting to wind down.  The only pure white orchards remaining are late varieties, mostly Butte-Padre blocks.  Many Carmel, Monterey and Wood Colony trees remain near full bloom.  The feared "flash bloom" did not materialize.  It has been a nice long period of bloom.

ANYA

 Photos taken 3/5/2013

The Candycots are beginning to wake from their winter slumber.

YULIYA

At about 1% bloom the Anya blooms are mostly on the basal portions of the branches while the Yuliya blossoms are mostly towards the terminals.

It could be that we do not have adequate chilling hours during our winters for the bloom to be compact.  A staggered bloom is not necessarily a bad thing.  By the time the fruit is maturing, the differences of bloom timing will be diluted.  Also, the fruit requires two or three picking passes anyway.

We had some rain last night, a bit less than an tenth of an inch.  Today is cooler and cloudy but there will be some bee activity with highs in the mid 60's. Bloom is hanging on, not a lot of petal fall yet.
