Mike, by the way, what type of orange was it in your picture, was it a Navel orange?

Well I guess I will amend my above post to:  peel splitting can be caused by sever calcium deficiency in very RARE conditions.  However, Fruit splitting occurs the world over in areas of good calcium soils.   Thanks for the info.

Mike T, I have never heard nor read that rind split was caused by a calcium deficiency,  Splitting is most common in sweet orange and mandarin cultivars.  Splitting normally results from the failure of the rind  to expand as fast as the interior locules of the fruit.   It is thought to be related to fluctuations in temperature, humidity, soil moisture, and cultural practices including irrigation and nutrition. Splitting of Navel oranges is commonly seen in response to winter rains.

I remember Dr. Malcolm Manners writing in a thread on the old forum, that in all his years with citrus, he never seen a citrus tree deficient in calcium.

In citrus, a magnesium deficiency always shows up on the tree's older leaves.  This is because magnesium is a mobile element, capable of moving within the tree,   When the tree's new leaves become deficient in magnesium, the tree "realizes" that the new foliage are much more important to the trees growth and the tree's life span than are the old mature leaves. The tree is in it for the long run.  Therefore, it takes the magnesium out of old mature older leaves and sends it to the new foliage. Therefore it is the older leaves that actually show the deficiency.

I think the Rubidoux trifoliate was named after the Rubidoux mountains near Riverside, California

Magnesiiium = in a magnesium deficiency the older leaves lower center portion shows a green delta shape while tips and leaf sides are yellow.

Citrus General Discussion / Re: More HLB In California
« on: May 29, 2018, 10:55:08 PM »
More than 100 Asian Citrus Psyllids recently found in San Obispo county California so far this year. County officials say the psyllids were brought in by people buying citrus from out of the county.

60
I have a dozen or so 1-year old Blood Clementine seedling trees  that are now about 15 inches tall.

61
There are only two ways for soluble salts (fertilizers, bio-carbonates, sodium etc) to get out of a container.  Either the plant absorbs them, or they are flushed out with a lot of water. If the water used to flush the container is not either rain water, or distilled water, it too could be adding additional soluble salts with each watering.  If the  small tree's root system does not fill the complete volume of the container, these soluble salts quickly begin to accumulate causing many problems for the tree.  If the medium is frequently flushed to remove the harmful ingredients, the unused portion of the medium is constantly water longed and compacted.

Citrus General Discussion / More HLB In California
« on: May 24, 2018, 12:19:25 PM »
The number of HLB detections in Orange County is booming. So far, more than 330 total trees have been confirmed to be infected by HLB, making Orange County the highest concentration of cases thus far in California. By comparison, over 230 trees have been confirmed in Los Angeles County

It was common thought that it was beneficial to line rocks  or other chunky ingredients along the bottom of a container to promote drainage.  However, it is now known that doing so is not a good idea, as it simply raises the perched water higher into the container, leaving less room for root growth.  A growth medium for a citrus tree, MUST provide good drainage, and good air porosity. Most mediums made from straight bagged potting soils meet these requirements ONLY for a short period of time, then problems will quickly begin. Dr. Carl E. Whitcomb, Ph.D  in his book "Plant Production In Containers-11" recommends a 3-1-1 mix made from 3 parts 1/4"pine bark (or other conifer barks), plus 1 part good Canadian peat, plus 1 part concrete sand.  I've used this mix with citrus and it works well.  Other growers I know use what is called a 5-1-1 medium, which consists of 5 parts small bark, 1 part peat moss, and 1 part perlite.  This medium also is reported to work well, but requires very frequent watering, and has a very fast water pass through (which might not work well in your Mother-In-Laws living room rug.   

64
Most literature claim the Inchangensis is hardy to 0-F (-18C)

66
After a person has grown container plants for a while they can easily tell how much water remains in the medium by simply lifting the container.

67
Recently I've been reading advice that when a container tree has a couple inches of the root ball cut and then the tree being put back into the same container, that trimming back the foliage is not necessary.  Also when I fertilize a tree I dissolve the fertilizer  and pure it over the entire surface of the root ball, so that the entire root ball is evenly whetted..

Kaidback, in a hot climate terracotta is a good choice as water passes through the container keeping the medium cool on hot days.  Plus it is a good looking container.

Citrus General Discussion / HLB & Brazil
« on: May 14, 2018, 12:51:10 PM »
Orange production in Brazil’s citrus belt is forecast to drop by almost a third during the 2018-19 season, according to an industry association. The decline is attributed to disease, mainly citrus canker and citrus greening (HLB). The number of properties producing oranges over the last few years has shrunk by 20%. Sao Paolo Agriculture Secretary Francisco Jardin said that although the state’s orange industry remains one of the largest in the world, the high number of abandoned groves was a concern.

70
The tree looks very good, watch for the future of the tree.  From what I understand heat does not completely cure the HLB but does set the disease back.

71
Non Poncirus cultivars have straighter thorn, flying dragon cultivars have strongly curved thorns.  Further the trunk and branches of FD will have a pronounced zig-zagged growth.

72
JJROSS54 no.  The real FD cultivar is the only truly dwarfing citrus variety.  Many of the poncirus varieties produce semi dwarf trees.

Citrus General Discussion / Re: Growing lemons from seed?
« on: May 13, 2018, 04:10:22 PM »
Over the years I have started numerous trees from seed.  Out of all of these seed grown trees, only one tree, a Saint Dominic Sour orange tree ever grew for a long enough time, and grow high enough to fruit. It is planted in a bottomless Root Maker expandable container. The roots have grown into the ground.  This tree now produces a good amount of fruit.

74
Z-willis, i noticed that your medium was a mixture of 5 different ingredients.  Good mediums rarely, if ever, are made up of more than 3 ingredients .

75
Note that Flying Dragon (FD) seed do not produce the true FD cultivar 100% of the time.  Only about 50 percent +- will be the true cultivar.
