Spring Bloom Season Spray for blossom blight when female flowers appear tiny nuts with feathery pistil and at 7 day intervals until rainy weather stops. Blight appears as black blossom ends of nuts in June and later as black hollow nuts. Remove all weeds from tree base to reduce competition and pest problems. Fertilize mature trees with 5—7 lb. Summer Growing Season Keep tree base dry to reduce crown rot problems. Irrigate trees at the drip line but away from trunks. Sprinkler irrigate with about 3" water every 3—4 weeks or drip irrigate daily during May-Oct.
Some orchards are fair and other orchards are definitely not worth picking. We have a big crop with damage to the trees that's unbelievable," Lauenroth said. I've never seen anything like it. Lauenroth said he believes this will also affect the operation of his commercial walnut dryer, which typically runs six days a week during harvest. Ken Mitchell, who grows walnuts in Sacramento County, said he has observed only minor damage to his walnut trees this year.
The tree dies except all of the way down to the stump, and then the tree comes back as just wild growth," said Mitchell, adding that reasons for the tremendous amount of damage are not totally clear.
Farm advisors believe that the cause of freeze damage to walnuts is related to wild swings in weather that happened in November In early November, temperatures were around 80 degrees, and they dropped well below freezing on Nov. UC Davis plant physiologist Maciej Zwieniecki explained that during the warm daytime temperatures, limbs contain starch, which does not provide protection from freezing.

Of the many varieties of English walnuts grown in California, there are four that predominate: Hartley, Payne, Eureka and Franquette.
Some are cultivated to be sold in the shell, whereas others are cultivated for the nut meats. Walnut trees start to leaf in early spring, and that is when the first little green nuts begin to appear. As the walnuts mature, the tender green hull covering the nut darkens to deep brown, then dries and breaks apart to reveal the hard, tan shell within. Depending on the variety, walnuts are ready for harvesting from mid-September to early November.
Farmers harvest the nuts by shaking the limbs of the trees until the walnuts fall to the ground, then are gathered immediately before they are discovered by discerning insects. The walnut is an extremely versatile nut, not only used in desserts and sweet breads but added to dressings, sauces, salads and meat, fish and vegetable dishes.
I remember tasting this liqueur in an Italian hill town on a chilly, fog-shrouded night. The liqueur perfectly reflected the surrounding landscape, which was heavily wooded and hauntingly beautiful. Walnuts can be candied, packed in honey, pickled and used in sweetmeats. My mother told me about still another use. During World War II, when all the shops and beauty salons in her hometown of Palermo were closed, her grandmother, a refined and formidable businesswoman, would boil the green hulls of unripe walnuts and use the black dye extracted from the skin to tint her hair.
I always feel that new-crop foods should be enjoyed at their simplest and most direct--unadorned and unencumbered, and as close to the natural state as possible--since this is when they have the most to say to us.
I suggest that you try new-crop walnuts accompanied only by good country bread and perhaps a small glass of red wine. Or spread a slice of whole grain-bread with sweet butter and top it with walnuts. Starting from this point of simplicity, you can begin to incorporate walnuts into other cool-weather dishes. Just make sure that the walnuts you use are fresh.
