Brian, wating to hear the out come if you use the 21%.

The Jaffa Red pummelo is the same fruit as the Chandler Pummelo just another name for the same fruit. . (Siamese Sweet x Siamese Pink)  They are a good tasting fruit, but I would not say that they are extra sweet.

The HLB carrying psyllid has been found in San Francisco’s Marina district, prompting state agricultural officials to declare a quarantine in the entire city of San Francisco thursday to stop the bug from spreading to nearby areas.

I also have a Dekopon tree growing in the ground and close in proximity with many other citrus varieties. The fruit are always seedless.  As to Dekopon's sweetness, there are two items that you must take into consideration.  First, is the age of the tree.  Older trees produce fruit of much higher quality than young trees.   Second, grafting Dekopon on a tree which other varieties are growing, and then growing that tree as you would any normal citrus tree is not how a Dekopon is supposed to be grown.  A Dekopon tree is supposed to be grown exactly like a peach tree is grown (pruned to keep the tree's interior open to high sunlight)   High sunlight both exterior and interior, PLUS lots of heat will produce sweet and large fruit. You can find information on the Internet on how Dekopon is grown in Japan, where the fruit was developed and is widely grown.

The Wonderful Company, the growers of Halo mandarins, which are found in stores all over the country, are now the largest farmers in the United States.

I believe Ventura is Eyeckr's last name.  I think he developed the Ventura lemon.   He sent me a fruit 3 or 4 years ago.

Certain aspects of citrus flower development derive from the nature of citrus as a tropical/subtropical evergreen which, unlike deciduous fruit trees, does not have true dormancy.  Deciduous fruit trees form flower buds during early summer. These flower buds complete their development prior to the onset of winter dormancy and appear to be ready by the fall for the burst and bloom of the following spring.  In citrus, flower bud differentiation starts during the winter and moves without interruption towards floral development and bloom. The one notable exception is Poncirus trifoliate, a monospecific genus.  Poncirus species has scale protected flower buds which are initiated during summer. Bloom occurs in early spring, on leafless branches which have completely shed their characteristic trifoliate leaves at the beginning of winter. (Biology of Citrus)

Charles nice seeing you posting again.

Yorgos, never spray ANYTHING whatsoever when the tree has open flowers in full bloom

Difficult to say.

In Garyk's tree case I don't think temperature is much of a concern, as the tree are evidently indoors and not out in the weather, 

Shout probably works like a soap/detergent spray.

SoCal2warm, all of my trees are growing inside of a large greenhouse on our farm.  The green house was originally used to start various plants that we then mechanically transplanted into our farm fields.  For the last 20 years we have all of our fields planted into wheat, so we no longer use the greenhouse.  I then converted the greenhouse into my hobby greenhouse.  I have 9 citrus trees and one pomegranate that are  planted in the ground inside the greenhouse.  They are all large trees.  There are also approximately 50 pineapples, and 30 container citrus trees planted in mostly 13-gallon containers.  I also have a large New Zealand Lemonade tree in a 3 cubic foot container.  Plus the normal misc. items like tomatoes, orchids and etc.
