I have a Fukushu kumquat growing in a 10 gallon air root pruning container.   I noticed a few small branches dying back.  I thought it was not getting enough water, so I increased the amount and frequency of irrigation.  The die back continued.  Therefore, I thought it probably needed re-potting.  When I pulled the tree from the container I quickly seen that the water was channeling through the medium.  A good part of the medium remained dry even though I applied a good quantity if water.  I removed a good portion (but not all) of he old medium and replaced  with a 5-1-1 medium (5 parts Repti-Bark, 1 pert peat and 1 part popcorn sized perlite and soaked the tree for 4 hours.  Be careful with large containers and watch for signs of trouble, and take action quickly when signs warrant it.

Citrus General Discussion / Greenhouse Shade Screen
« on: May 25, 2020, 11:13:13 AM »
In the past I have used a black shade screen to reduce the heat inside the greenhouse from the summer sun.  This year I purchase a reflective silver coated shade screen  called Aluminet Bulk Shade. It is not as heavy as the black shade screen that I had been using, and is a lot easier to put on.  The one I purchased reduces the incoming light by 30 percent, by reflecting the suns rays back into the atmosphere. .  With the Aluminet Bulk Shade cloth covering, and the greenhouse's exhaust fans, the greenhouse is doing just fine keeping the greenhouse at reasonable inside temperatures..

Citrus General Discussion / Horticultural Oil For Insect Control
« on: April 30, 2020, 09:59:15 PM »
For a complete elimination of insects listed below, and for ultra safe personal protection, use a good horticultural oil.  It eliminates most all common insects that attack citrus. Can be sprayed between 32F to 90F.  Insects NEVER become immune, no matter how often or how long horticultural sprays are used.  Be sure to keep ingredients (water & oil) blended while spraying

Insects killed:
Rust mite, red spider mite, scales, white fly, thrips, mealy bug, aphids, Greasy spot, loosening of sooty mold.

Citrus General Discussion / New HLB Areas In California
« on: April 30, 2020, 04:20:03 PM »
A new finding of huanglongbing (HLB) has been reported in a residential citrus tree in the city of San Bernardino, California. This is the first confirmed find of the citrus disease in the city and follows the recent detections of several HLB-positive trees located in Colton, Montclair and Ontario.

Citrus General Discussion / USDA Allowing Chinese Citrus Into Thle USA
« on: April 23, 2020, 03:05:03 PM »
With all the problems that the USA and the Citrus industry is having, why on earth would the USDA allow China to begain selling their citrus in the USA.

The chief executives of three large U.S. citrus grower associations, estimate that the financial loss due to Chinese COVID-19 as of April 9 is over $200 million.”

Citrus General Discussion / Found This Interesting
« on: April 12, 2020, 03:23:00 PM »
The wage rate for citrus harvesters hired in Florida under the foreign workers program H-2A program, also known as the Adverse Effect Wage Rate (AEWR), was $11.20 per hour in 2017. In comparison, Florida’s minimum wage in 2017 was $8.10 per hour.  Surprised me, as it was higher than Florida's minimum wage at that time.

Citrus General Discussion / Shasta Gold Mandarin
« on: March 21, 2020, 07:41:50 PM »
I purchased a Shasta Gold mandarin from Logee's greenhouse and planted it on October 18, 2019 in a 3-gallon Root maker air root pruning container.  The tree is planted in a 5-2-1 medium (5-parts Repti-bark wood chips, 2 parts peatmoss 1 part perlite).  This is a highly aerated and rapid draining medium, so I water the tree by soaking the entire container for 1 hour per week (at least at this time of year).  An hours soak allows the Repti bark to absorb up a supply bank of water for extended use by the tree. Soaking the root system for this period of time does no damage to the roots.  A citrus tree can remain submerged for two days before any root damage begins to occur.  In the 5 months since the tree has been planted, it has had one flush and one flowering.  However, the tree dropped all the small fruitlets from this initial bloom.  I expect that the next flowing should be around August.  If at that time some fruit is retain, I will allow the tree to keep one fruit.  Retaining one fruit, even on a young small tree, does not effect the trees potential growth at all.  This is because all the energy a fruit requires to produce and grow to maturity is derived only from the 3 or 4 closest leaves to the fruit, and not from the entire tree (research my Karen E. Koch U. of Florida). For container growing I find the 5-2-1 medium works very well.  An additional 5-2-1 advantage, is one does not need to worry about over watering.  I fertilize the tree with Jack's professional 25-5-15 w/micros fertilizer.

Citrus General Discussion / Saint Dominic Sour Orange
« on: February 01, 2020, 02:15:55 PM »
My in ground Saint Dominic Sour Orange tree is producing new flushes of growth on each and every branch tip of the entire tree.  100 percent of the tree is producing a flush.  Never seen such a complete flush on a citrus tree before

Researchers have learned that HLB causes severe secondary and micronutrient deficiencies in infected trees, especially in the roots.  To compensate for these deficiencies, fertilizers need to contain the macro nutrients and especially enhanced levels of the of micronutrients, and the enhanced nutrition needs to be provided constantly year around. The most practical way for homeowners to achieve this is by using controlled release fertilizers (CFR). Several companies are now making quality enhanced CRF citrus packages with release times ranging from 2 to 12 months. For homeowners, 2 applications of a quality 6 month product, or a single application of a 12 month product should work fine.  According to the University of Florida research, this method of nutrition is working wonders for HLB infected trees.

« on: January 19, 2020, 02:51:28 PM »
MANDARINS
Sugar Belle:  Most tolerant citrus variety, Taste much like minneola, but with better color.

Mandarin Hybrid 13-51 : Just released  both to industry and door yard growers by UF/IFAS:  Produces beautiful fruit.  A very attractive deep orange color. A very easy peeler.  Shows good tolerance

PUMMELOS
Pummelette : (Formally variety 5-1-99-2)  Grapefruit sized dark red flesh, with an exceptionally great flavor.

Monster (Formally variety N40-7-4)  A very large, some as large as a bowling ball.  Exceptionally sweet grapefruit type flavor.  Thin skin with large segments.  One large fruit can feed a small family.

I was reading an article in a text book  titled "Advances In Citrus Nutrition", published by the National Research Center for Citrus, that concerned floral spraying of citrus with a solution of products derived from the meat waste industry.   It said....In the case of biostimulators obtained from animal tissues, they contain numerous organic and inorganic compounds naturally occurring in these organisms, and exhibit a broad spectrum of the physiological and biochemical influences on plants.

The article did not go into a deep explanation, but did say that in many countries, this type of biostimulation is gaining popularity.  Of course many of us have heard of using sprays directed from the fish industry, but this is the first time I have come across using sprays derived from the meat waste industry. Personally I have never tried it.

Citrus General Discussion / Brazilian Citrus
« on: December 21, 2019, 02:15:12 PM »
The Brazilian citrus industry consists of approximately 195,275,000 trees planted on 1,010,229 acres on nearly 5,885 farms.  In 2000, the average tree number per acre was 148. This figure increased to around 222 in 2010, and today it is at approximately 265 tees per acre..  The incidence of HLB by tree age group is: 0 to 2 years, 2 percent HLB infected; 3 to 5 years, 7 percent; 6 to 10 years, 19 percent; and more than 10 years, 26 percent. Time from infection to HLB-symptom development is generally less than one year.

Citrus General Discussion / CUPS (Citrus Under Protective Screen)
« on: December 20, 2019, 04:10:02 PM »
An account of a growers field day held at a Florida CUPS (Citrus Under Protective Screen)1.3 acre screened grove at a U. Of Florida research field. A handout distributed at the field day stated that Ray Ruby, Ruby Red and Flame grapefruit, as well as Honey Murcott, thrive in CUPS. The handout indicated Ray Ruby grapefruit in the 2018-19 season, the fourth year of CUPS production, yielded an average of 892 boxes per acre with 100 percent packout. Honey Murcott yielded an average of 529 boxes per acre with 100 percent packout. The per-acre yields were extrapolated from actual production of .24 acres of Ray Ruby grapefruit and .34 acres of Honey Murcott. Revenues were $25.89 per box for Ray Ruby, or $23,094 per acre, and $42.48 per box for Honey Murcott, or $22,472 per acre.

Citrus General Discussion / Valentine Pummelo
« on: November 11, 2019, 06:27:04 PM »
My Valentine pummelo tree seems to bloom somewhat year around   However, spring has the greatest bloom.  Last season I left the off season blooms develop fruit, and they matured in late summer to early fall, normally Valentine matures January/February.  These off season fruit did not color up at all. the pulp remained white.  Further the pulp was somewhat dry and granulized.  I'm sure the absents of color was due to the absence of cold temperatures. Colder temperatures is required because the colorization is due to one of its parents being a blood orange. From now on I am going to remove all off season flowers, and only let the spring bloom develop so that the fruit matures later in the winter.

Citrus General Discussion / BRIX
« on: October 30, 2019, 08:50:11 PM »
Most people know when we talk about brix in citrus, we are referring to the sugar (sucrose) sweetness in a citrus fruit..  But what exactly is brix.

Brix is a measurement of sugar (sucrose) in solution, indicated in degrees.  One degree brix equals one gram of sucrose in 100 grams of solution (juice).

Citrus General Discussion / Getting The Best Bloom From Your Trees
« on: October 23, 2019, 03:11:53 PM »
Relatively low temperatures (night 50 to 55F and day 59 to 65F) promotes flowering in citrus. Also, increasing the exposure to chilling temperatures from 2 to 8 weeks increases the number of floral shoots and flowers per shoot, resulting in a concentrated spring bloom which in turn synchronizes both the fruit development, maturity and harvest.  While in ground outdoor trees must rely on the weather,  winter water deficit stress can be imposed on out door citrus trees of all cultivars to compensate for inadequate exposure to low temperatures during mild winters.  In door and greenhouse trees can easily be temperature controlled to produce the above results.
