Citrus General Discussion / Re: Mexican Lime Tree Problem
« on: July 18, 2022, 12:01:10 PM »
Like Jakefruit intimated, one of the very first things a person thinks of when a newly summer planted tree in Phoenix is having problems, is the watering schedule.  In  the Phoenix area I would plant a new citrus tree in the fall months.

I used to have a large in ground Bizzarria orange tree (6-ft.tall and 8-ft wide) It produced a lot of fruit, but the only thing one can do with the fruit is look at them.  I finally chopped the tree out and replaced it with a Red Grapefruit.

Citrus General Discussion / HLB Spreads In California
« on: July 08, 2022, 12:55:08 PM »
USDA APHIS added portions of Los Angeles, Orange, Riverside and San Bernardino counties to the quarantined areas. With the expansion of the Jurupa Valley and Riverside areas of Riverside and San Bernardino counties in the HLB quarantine area, CDFA merged the HLB quarantine boundaries, creating a single HLB quarantine. That quarantine expands across Los Angeles, Orange, Riverside and San Bernardino counties. In addition, APHIS is establishing a quarantine in a portion of San Diego County. APHIS is taking this action because of HLB detections in plant tissue samples collected from multiple locations during routine surveys in California.

Have you ever pulled the tree from the container and examined the roots?

Every container has a layer of perched water, even containers without an actual bottom.  Roots will not grow in the perched water portion of the container.

Covering the entire root ball with the medium, has nothing to do with the purchased water table.  Looking at the picture again, it certainly looks like the container is not completely filled. 

Why is the container only 1/2 full of medium?  The perched water table must occupy most all of the tree's root zone area, educing much of the root's oxygen. 

My guess all  the trees that cannot stand on their own roots were transplants, that were not planted properly,  For now stake them up.

I noticed you listed Ponkan Mandarin on the don't want list.  Ponkan is not only a good fruit, it is a great tree..  I would urge you to reconsider.  You will be happy if you do.  Thanks for sharing.

The 1,000th tree okayed for growing by California’s Citrus Clonal Protection Program happens to be California's oldest orange variety in the state. Dubbed the Mother Orange Tree, Bidwell’s Bar is a sweet Mediterranean orange brought to California from Mazatlán, Mexico, and planted in 1856. It was first planted near the Bidwell Bar Bridge near Oroville.

The tree’s survival skills are some of the reasons Tom Delfino, former California Citrus Nursery Society director, recommended it for the protection program. “Apparently this variety is very rugged,” Delfino said. “Not only has it survived a lot of cold Northern California winters, but the tree has been dug up and replanted twice — once to protect it from impending flood, and again to make way for the Oroville Dam.”
By suggesting Bidwell’s Bar for approval, Delfino was hoping the protection program would clear it so he could buy its budwood. On the occasions he has visited the original tree, Delfino said the fruit in reaching distance was always gone. “I think it must be tasty because locals grab it for themselves,” he said. “Makes me even more eager to grow and eat my own.”
Delfino also hopes that this variety will catch on with commercial growers. “My thought is our citrus industry is concentrated in the southeastern San Joaquin Valley and is subject to a number of pests that like the warm climate there,” Delfino said. “Though this has seeds, which may be a deterrent, it can be grown in colder areas that discourage some of those insects.”
California’s oldest orange tree arrived in California nearly two decades before the better-known Washington Navel orange grown by Eliza Tibbets in Riverside. “Bidwell’s Bar is an example of what was grown in California before the Washington Navel came to dominate,” said Tracy Kahn, curator of the Givaudan Citrus Variety Collection at University of California, Riverside (UCR).
Kahn says it’s important to preserve the genetic material from a tree with such significance to California. “Some people were worried it was going to die, but now we have an officially cleared source of this historic tree, and it is protected for future generations,” Kahn said.
The Citrus Clonal Protection Program, housed at UC Riverside, is the first of its kind in the world. It began in the 1950s, and its scientists spend up to three years testing and clearing citrus trees of disease so they can be released to commercial and private growers. By law, every citrus tree newly propagated in California can be traced back to one mother tree created at UCR through the protection program.

Good job Poncirus Guy.

Bret, long time no see.  Welcome back.

I don't know about grafting onto a lemon rootstock.  However, almost nobody ever uses regular lemon rootstock, so there must be a reason. I have heard that it  produces very bland fruit.

Mother Orange tree.   In 1856 Judge Joseph Lewis purchased three sweet orange seedlings from Jesse Morrill in Sacramento, California, and these were planted in the vicinity of Oroville, California in Butte County. One of these trees was planted at the west end of the famous suspension bridge at an area known as Bidwell's Bar and is still living and bearing large crops annually. It has come to be known as the Mother Orange Tree, and is now apparently the oldest and largest living orange tree in California.  Measurements made by an official committee on November 27, 1926, gave the size of the tree as follows:  Height 33 feet 6 inches, spread of top 31 feed 5 inches, circumference of trunk one foot from the ground 66 inches.  The tree is still alive today.

Thanks G for the video.  I remember Greg from the old forum. If I remember correctly, Greg also won an award form the Canadian back yard hockey ring contest, for a back yard hockey ring he built. That contest is a national contest in Canada.

Young leaves transpire at a higher rate than mature leaves.

As far as cupping, your tree looks normal.  However, your tree looks greatly underfed.  How often do you fertilize the  tree?  Also what is all the white stuff on the fruit and leaves. -It could be mealy bug.

 Length of time to flower from planting the seed. Most oranges and grapefruit require 7 - 10 years. Calamondin & Key Lime 2 to 3 years.  Mandarins 3 to 5 years. Yuzu I do not know the time required until flowering.

Many times it is a watering problem.  When the tree is parched and receives a lot of water, it absorbs the water so fast the fruit expands rapidly and the fruit splits.  Try keeping the root zone evenly moist.

The 2.5 year old tree should b e fertilized 4 times per growing season. and the 4 year old tree 3 times per growing season.  The University recommends fertilizing with a 6-6-6 or a 8-8-8.  The best to you and your trees.

No not citrus greening.  Many of the leaves are just showing that they are old.  A citrus leaf has a life span of 18 months.  How often do you fertilize your tree, and how old is the tree/

I get plenty  fruit from my in ground Valentine Pummelo tree.  The problem with Valentine fruit is that they are just sweet and absolutely zero acid, flat insipid.

A tree that size without bloom must be a seedling grown tree.  Normally 7 - 9 years from planting to bloom for your seedling tree.

My FFP produced one fruit its second year, then none the next 2 years.
