SoCal2Warm, in locations that citrus is capable to be cultivated, it is during the winter months that citrus develop the flower buds that will be ready to bloom the following spring.  Is this true for citrus out doors in a Siberian winter .... I'll leave the answer to that question up to you.

Bonsai Beast, I assume your tree has not begun to flower in your area.  You can apply low biuret urea if the bloom has not yet started.  It would have been better if you had sprayed 1.5 to 2 months prior to expected bloom date, but a late spray will still be better than no spray. Then after your trees bloom, new fruitlet set, and the early drop period (where the tree drops some of the small fruit that it set) a second urea spray should be given.

Citrus growth greatly slows down when the temperature is below 55.4-F (12C),  but  citrus does  not go  completely dormant during the winter.  Unlike deciduous trees that develop their flower buds during the fall months, citrus develop flower buds during the winter months which will then bloom in the spring..

I had mealy bugs on an in ground pomegranate.  I used a hose with an attached adjustable brass nozzle to wash them off the tree just as Spaugh wrote.

druss, I see from your pictures you are growing in totes.  Good idea.  I have many empty totes, which I acquire from the business were in..  However, because I live in a cold winter location, it would be difficult to move them in and out to protect them from freezes.  Still in a warm location they would be great.

Pin hole or not, it still Is some sort of a navel orange.  After tasting how would you rate the sweetness?

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.

 Minneolas at the supermarket are mostly necked fruit, however there are also always some minneolas that have no neck.

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.

Shaneatwell, leaving grapefruit attached to the tree until late march accomplishes two things.  First the extra heat produces additional sugars, and second it also reduces the acidity..  I acquired this information from Dr. Malcolm Manners who is the head of the Citrus Culture department at Southern Florida University.   I have an in ground Marsh seedless grapefruit tree (white flesh) and I always wait until the last week of March to pick the fruit.  It does make a big difference. Lastly, the age of the tree makes a BIG DIFFERENCE in the quality of the fruit.  You should not expect much from a young tree.

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.

First of all, Oro Blanco is not a grapefruit, but it is semi sweet.  Actual grapefruits are not supposed to be sweet, they are supposed to be tart. Its like asking what is the sweetest lemon. Red Grapefruits are sweeter than white grapefruits . To sweeten up a grapefruit, leave them hanging on the tree until late march.  The hotter the weather the fruit is grown at, and the older the tree, the "sweeter" the grapefruit (note Sweeter was in quotes as no grapefruit is really sweet).  If you want a really sweet fruit, you will probably have to look somewhere else than grapefruit.

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.

It is a nitrogen deficiency. The symptoms of a nitrogen deficiency in citrus are:  Severe --- totally yellow leaves with no variation of color, or yellow/orange veins with some green out on the far sides.  Less severe - Shows up on older leaves with newer leaves still retaining some green.

Citrus are heavy feeders and require more nitrogen and potassium than many other types of fruit trees.   It would be helpful to know the fertilizer you have been using on this tree, and the schedule of application.

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.

you might be able to get either a fruit or perhaps seed from Eyeckr  a member of this forum.  The lemon is named after him.

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)

I read that article, found it very interesting indeed, but rather difficult to completely understand in its entirety.

Charles nice seeing you posting again.

It is not recommend spraying extra amounts of Low Biuret urea if you missed one application period. 

edweather,  most definitely spray the underside of the leaves, as the underside of the leaf contains by far the most stomata (openings) in the leaf.

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

911311, not all Flying Dragon seed are true to type.  Approximately only 50 percent of Flying Dragon seed will produce true to type, no matter the age of the mother tree.  Flying Dragon as a cultivar always has zigzag stems and strongly curved thorns.  It is an easy way (without a DNA test) of selecting predominantly true clonal FD seedlings, while discarding those which are obviously and definitely  genetically different.  All straight stemmed and straight thorn are not FD.

Ilya11 what reaction do you think the enzyme (there are at least 6 different protepytic emymes) has on the scale?
