Grapefruit are sweeter when grown in sticky humid locations with high heat, because high humid climates have little change in day/night temperatures.

I planted a grapefruit in the ground in 2014.  I could not find a Duncan, so I planted the next best thing (in my opinion) a white Marsh grapefruit.  I remember Dr. Malcolm Manners once wrote that the best grapefruit he ever ate was a Marsh that he picked off a 25 year old tree.  I also at times purchase red grapefruit from the market, and they are OK but don't have the old time grapefruit taste,.

If you want a citrus to have a long life in an area with citrus greening (HLB) you have to construct an insect proof screen enclosure around the tree, so the psyllid cannot reach your tree.

Citrus General Discussion / Re: Dealing with Cold Damage
« on: March 23, 2017, 10:02:31 PM »
In treating trees severely injured by cold, three courses of action are open. (1) Leave the tree alone: (2) cut the tree back to the ground: (3) cut the tree back part way.  Everything considered, leaving the tree alone is always the best plan.  For some time following a freeze-injury it is impossible to determine how much pruning should be undertaken.  If cut back to the ground, more of the tops may be removed than necessary, and if headed back part way they may have to be pruned over again at a later date..   There is no need for haste.  nothing can save trees or parts that have been frozen.  Much expense and labor is prevented by waiting until the extent of the injury can be determined. This cannot be decided until the new growth starts. (Cultivation Of Citrus Fruits--  Author Hume)

The number one killer of young citrus seedlings is stem rot (Rizoctonia).  At first water only in the mornings, and them\n put the tree in an area where it gets full sun.  Doing so will quickly dry off the surface of he medium and thus prevent fungus.  You can begin lightly fertilizing when the first true leave appear. Be sure the medium you plant the trees in have GOOD drainage. The best to you and your seedlings.

Cara Cara should also be good,  They grow Cara Cara in Valenzuela+ which probably has much the same climate as you you have in the Philippines.

Any pH meter under $100.00 is probably not worth buying.   A good moisture meter is the human index finger.

Alaska fist oil is used as a foliar spray.  Use whatever fertilizer program you wish, but know that citrus are heavy feeders requiring more nutrition than most plants.  Citrus preform much better with conventional fertilizers than with organic fertilizers.   When watering large /deep containers know that when the top couple inches feel dry, deep down in the root system it could still be very wet.

When you  plant your seedlings in a container, just be sure that whatever medium you use, that it has GOOD drainage.  Etrog require a medium with approximately 25 percent aeration. Water when the top 2 inches feel dry.

The roots looked very healthy when you transplanted from the 1/2 wine barrels into the 55 gallon drums.  We have not seen a pictures of what the roots look like after being in the 55-gallon drums for two months.  One comment -- There is always an increase of leaf drop when a citrus tree blooms.  I did notice in the first set of pictures, that the leaves showed a deficiency of magnesium, and probably also nitrogen. Have you already moved the trees out of the 55-gallon drums?  If so what did what was the condition of the rot systems.

Citrus General Discussion / Is Dekopon An Alternate Bearing Variety
« on: March 20, 2017, 01:05:15 PM »
Is Dekopon an alternate bearing variety? My Dekopon tree produced it first real crop last year, The tree has already produced its first 2017 flush of new growth with only 3 or four blossoms.  One of Dekopon's parents is Ponkan, which is an alternate bearing variety. .

Samu, no I did not cull any fruit from the grapefruit tree.  A citrus tree will retain only the amount of fruit it is capable to bringing to maturity.    Besides at the time of the first fruiting the tree was approximately 3.5' high and 4 ' wide.

Top quality grapefruit has a high heat requirement, so is best suited to tropical and hot, humid, subtropical climates. Tangerines,Kumquats and limequants are produced primarily in China and the Philippines, they are eaten fresh or candied with the whole fruit - including the peel - being consumed.Of the round oranges the one most suited for warm climates would be Valencia.

bsbullie, that seems strange, as the Cara Cara originated in, and is heavily grown in Venezuela, which is certainly a very tropical country.. Venezuelan Cara Cara are always pink.

Thanks.  I notice in the video they spell the name wrong.  The correct spelling is not pomelo, but rather pummelo.

Cara Cara, whether grown in Colorado or Florida should turn pink.  Because the coloration of the Cara Cara is caused by the chemical Lycopene, it will produce pink colored fruit when grown at any location or in any temperature range.

Mike  T, thank you for your postings on this thread.  I totally agree with you when we talk about insecticides in general.  In this particular case, the case of Imidacloprid and its use on citrus,  I personally believe it can be used in a safe manner with little danger to bees, and for that matter for humans.   A couple reasons.  Imidacloprid is used throughout the citrus industry in a truly  incredible volume, and with little or no bee kill reported. The USDA/EPA has allowed a zero (0) day interval between application and harvest. Zero day harvest is very rare in the USA. Umpteen billions of oranges have been treated, harvested and consumed with no implications.   Of course it comes down to a case of personal choice.  One can either use it or not.  I personally can see no reason not to.

gardennewbe a couple questions;

!. How long has the trees been growing in the 55-gal. containers
2. What is the watering schedule for these trees.
3. What is the formula of the fertilizer you use.

From looking at the pictures the leaves show very little if any green coloration.  They  look to be greatly under nourished and deficient in nitrogen, magnesium and more than likely other nutrients also.   Growing in very large containers, especially for undersized trees, can be really quite difficult, and requires much knowledge on nutrition and watering.  Looking at your pictures, those containers are much to large for such small trees, It can be done, but most people (and trees) run into to trouble.   I'll await the answers to the above questions  .

Citradia, below is the Imidacloprid label.  For citrus the Pre-Harvest Interval for Imidacloprid is 0 days.

Imidacloprid kills leaf miners.  Certainly when you feed almost any insecticide directly to a bee it's deleterious--bees are highly susceptible to many classes of insecticides.  However, imidacloprid, applied to the root system of a citrus tree seems to be fairly safe if used according to the label.  The Florida citrus industry uses incredible amounts of it, and they do not see bee kills. The so called "sudden death" syndrome of bee colonies, which was at one time attributed to imidacloprid, now seems to have nothing to do with that material. An interesting aspect of imidacloprid is that it does not move very well into flowers.  That is a real problem in the cut flower industry, in that you can't get it to control thrips or other flower feeding insects - it just won't go there.  But in the case of the citrus industry, that is a good thing--it doesn't seem to affect the bees collecting pollen from our citrus flowers.   (Taken from notes received by Dr. Malcolm Manners)
