A residential grapefruit tree in the city of Riverside near the Interstate 215/Highway 91 interchange has tested positive for the incurable citrus disease Huanglongbing, or HLB, which causes the citrus greening disease. This is the first case of the disease in Riverside. It has already been detected in LA and Orange Counties. It was found after several Asian citrus psyllids (or the insect that moves the bacteria from tree to tree) trapped in the area tested positive.
Brownish adult, yellow nymphs, and white wax of Asian citrus psyllids, below.
After the results came back July 25, the tree was removed the following morning. A nearby tree is also being tested and all trees within an 800-meter radius from the infected tree that are susceptible to the disease will be treated to reduce the numbers of Asian citrus psyllids.
Infected trees have mottled leaves and fruit that is misshapen the fruit stays green and has a bitter taste. There is no known treatment for the disease and trees usually die within three to five years.
Researchers at UC Riverside and in UC ANR are working on biological controls, testing for effective insecticides, developing resistant citrus trees, and finding ways to detect infected trees earlier.
Information sheets, videos in English and Spanish, and other resources can be viewed and downloaded at: http://ucanr.edu/sites/acp/. They can help in identifying the Asian citrus psyllid and the disease symptoms and how you can help in the fight against this devastating disease.
If you see any trees that have any symptoms, contact your agriculture commissioner.
Information is also available on the state's Dept. of food and agriculture website. If you believe you may have an infected tree, call the California Department of Food and Agriculture at 800-491-1899.
UC Riverside and UC ANR are actively looking for donations to help pay for large screen houses (1 acre or more) to protect the important citrus collection.

National Spinach Day
By: Deborah Lewis -- March 26th is another super food holiday, spinach.
For inquiring minds: Spinach is a plant native to Persia (Iran). In the 7th century it was introduced to China and introduced to Europe in the 1th century. Spinach was brought to the United States in 1806. Spinach is known in the Far East as "the Persian Green."
There are three distinct groups of spinach. Savoy has dark green, crinkly and curly leaves. The flat, smooth leafed spinach is easier to wash and clean than Savoy. Semi-savoy spinach is a hybrid also with slightly crinkled leaves.
To best enjoy spinach it should be eaten fresh as it loses nutritional values daily. Refrigeration slows the deterioration with half the nutrients lose by the 8th day after harvest. Spinach should be frozen when fresh for long term storage.
Popeye the spinach man created a 33% increase in domestic spinach consumption during the 1930s. The industry needed the boost during the depression years. California is #1 in the U.S. of the states that supply and grow spinach. California provides 3/4 of the U.S. supply of spinach edging out Arizona, New Jersey, Texas, Colorado, Maryland and Arkansas. China is the largest supplier producing 85% of spinach produced in the world. The U.S. comes in 2nd with only 3% of global production.
Spinach grows best in the spring and autumn when weather conditions are cool and moist. It grows well in sandy soils.
Spinach can be used at every meal during the day. For breakfast, add it to an omelet or saute' the spinach or add it to a breakfast sandwich with eggs, tomato, bacon. At lunch, enjoy spinach in quiche with your choice of shrimp, cheese and oregano. Add spinach to salads with strawberries or other fruit. As a snack, spinach added to a smoothie provides a quick energy boost without fat and sugar. Finally for dinner add spinach as a topping to whole wheat pasta with or without other saute'ed vegetables.
Enjoy your spinach!

Miniature Floral Arrangement: Design Tips from the Experts (Series)
--GJ dePillis, Master Gardener--
February 20, 2015
As the fog clung to the ground one early morning in the California Botanical Gardens, I found myself surrounded by several floral enthusiasts, who had flocked here to learn from Joyce Dean, judge and winning contestant herself at more floral shows than you can shake a tulip at.
Today, Ms. Dean encouraged creativity, which all her protégés loved. It was noted that should a butler help the groundskeeper plant varieties which would bloom early, mid and late-season, there would be ample supplies to have floral arrangements in the home without having to call upon the florist.
During this seminar, we focused on miniature arrangements.
It was fascinating to witness - that although we had access to the same materials- each participant came up with a spectacularly different design.
We were guided through the techniques of making three-inch miniature arrangements, as well as an eight-inch design.
Now, why create miniatures nearly small enough to fit into a candle votive? Tiny floral arrangements are perfect "pick me ups" for those who are convalescing in hospital. Joyce Dean recently made several with her team of floral hero and heroines to give to those blessed souls recuperating at the Veteran's memorial Hospital.
Imagine if you were able to enlist the help of the household staff. You could create scaled-down miniature floral arrangements as a farewell gift for your employer's dinner guests? In addition to having a central display where the dining party spent most of the evening, each person could also have a tiny memento at their place, which the host could offer them to fondly remember the evening.
Small scissors, Toothpick, Tweezers, and of course a bit of water-soaked fresh flower floral foam
Sample places to buy supplies:
(Note: We were advised that if one becomes a member of the Flower Arrangers' Guild, they would have access to all the best suppliers and would not have to hunt the Internet)
Try arranging on your own and then next time, we will share some tips and you can see if those tips help improve your overall designs.
Until next time, remember to stop and smell the flowers.
