Citrus General Discussion / Re: Jackson grapefruit
« on: September 08, 2019, 02:15:14 PM »
Almost all citrus seedlings produce thorns until the tree develops maturity.  Most assuredly both of your seedlings will eventually produce thorns.  You are quite lucky to find a seed in a Jackson Grapefruit.  Jackson grapefruits were developed in South Africa as a limb sport, and are seedless..  I would love to have a Jackson grapefruit tree, mainly because this variety contains a much lower level of naringin, the chemical that gives grapefruits its bitter taste, thus they are a much sweeter and less bitter than the normal white varieties.  Unfortunately it will take approximately 8 to 10 years before the trees will begin fruiting.

In a follow up to Brian's post. I had a large in ground Bearss Lime tree.  It produced more limes then I could ever begin to use.  It only set one large crop per year, it did not bear fruit throughout the year.  I eventually got rid of the tree to replace it with a Valentine Pummelo due to the amount of space I have available to grown citrus.. Plus I don't use limes very much.

My Valentine pummelo has been in the ground perhaps 5 or 6 years.  I am really not sure.  However, in the time I have been growing it don't remember ever having to spray the tree for insects of any kind.

Common scale starts as an egg from its mother, usually on the leaves or branches of a plant. The egg then develops into two immature stages called Instars. The first instar stage are known as crawlers.  Crawlers move around the plant and in approximately one day's time settles down permanently on a particular spot of the host plant for the rest of their lives.  Then starts the second immature stage called the 2nd instar stage witch matures into the adult.  The adult causes all the damage to the plant by sucking out the juices of the plant. During periods of high temperatures scale can reproduce quickly.

The temperature has been in the nineties for most of the month, and mealy bug and especially scale has been a problem.  I have found then on Santa Teresa lemon, Dekopon, Cara Cara, Sour Orange and New Zealand Lemonade..  However, for the entire summer not one insect has been found on the Valentine pummelo.  In fact I have never had an insect problem on that tree.

Bomand, do you know the actual cultivar name of your poncirus seedlings?  I can see that they are not Flying Dragon.  they have a very healthy look to them.

Exactly, scion growth regulation of the various grafted varieties is always a concern with multi grafted trees.  In Joe Real's 100+ variety tree he  partially controlled this  problem by where on the tree he placed the more vigorous scions.  However, pruning was still required.

Very interesting and hopeful.  As always time will tell.

Nice going.

I would  not recommend foliar spraying every week.  It is not good to under feed a tree, and it is not good to over feed a tree, Desertcitrus could follow dihvac's  recommendation, but doing so every week would not be wise.

DesertCitrus, the deformed leaves are from insects.  It is very common with new growth at this time of year.  You can guard against this, by spraying the new grown  with horticultural oil or neem, every now an then until the leaves mature a little.  I had the same problem on a Page mandarin.  New growth is candy to insects. 

HardyVermong, nice article, thanks.  I kind of forgot about Bingo.

Hardy Vermont, great recommendation.  Sugar Belle came to my mind also.  If I'm correct, I believe Sugar Belle shows some tolerance to HLB but is not actually resistant.  Is this your understanding?

Desertcitrus, It has been a long time since I heard you last.  I remember you from a long time ago.  If I remember you live in the south west part of Utah off I-15.  Looking at your pictures I can easily see that some of you tree's leaves have become sun burned.  This is most probably from the 100+ temperatures and not enough water to sustain the tree during this time.  With proper care your  tree can return to it former health, but the sunburned leave will not rejoin their former coloration.  If the hot conditions should return be exceedingly careful not to let the tree become dry and without its needed  moisture.  The tree's roots draws up water that eventually reaches the leaves which transpires the water into the air to keep the leaves cool.  This can only happen when enough water is available to the tree.  I think your tree will be OK if you insure its care. It is very nice hearing from you again.  You have been growing citrus for quite some time.  Take care.

Harris propagates all of their citrus trees inside a USDA improved screen house.  Therefore, they can, and do, ship citrus to other states.  I'm in Colorado and I buy trees from Harris.   Even though their trees are USDA inspected and approved for shipment, I don't think they can ship into California.  Not being able to ship into California, is not Harris's fault,  but California's own ban on shipping citrus into their sate,  However, it would be worth a telephone call and Ruth at Harris.  There is a very slight chance, although I doubt it, that a California shipment could be possible, due to the fact that Harris's trees  are USDA inspected and insured to be disease free, and insect free.

I think I purchased my Xie Shan tree from Ruth at Harris, many years ago.

Citrus General Discussion / Re: Leaves Dropping Off My Meyer Lemon
« on: August 18, 2019, 03:20:34 PM »
As long as the wood remains green, the tree is still alive.  The Meyer lemons tendency to drop leaves and show signs of other concerns is very well known.  It is a very finicky plant.

Although we can gain some information from limited batch experiments, as Ilya11 writes above there is indeed a truer level of value in results gained from higher trial numbers.

Lavender87, in your above post you are grafting a scion cut from a mature tree onto a rootstock.  Yes, in that case the graft will produce fruit in a short period of time.  However if you graft a immature scion taken from a young immature tree, the grafted scion can take a long time until the scion grown and finally reaches its mature node count. You write that you can agree to some points of my original post.  After reading both of our posts I fail to see any differences, 

When a citrus leaf turns yellow do to a magnesium deficiency, they do not always regain their full green coloration depending on the severity of the deficiency, however all new growth does color up again.

Cindy, from your collection list if I could take one tree I would take the Xie Shan.   Xie Shan is a real winner,  I am not sure how old my Xie Shan tree is but it must be around 12 years+ old.

If you graft an immature citrus twig onto a mature root stock, the young citrus will not produce fruit until it reaches it predetermined node count required for maturity.  This could be either a shorter time, or a longer time depending on what node count number the grafted twig had reached when it was cut from the mother tree.  Citrus when removed from a tree, and then grafted onto a rootstock "remembers" what node count it had achieved before it was removed, and starts growing from that point.

WILL2358,  as you wrote the Australia Red Lime does taste ok, but it taste just like a lime.  My in ground Bearss lime produces a TON of fruit.  I also have  black Twig Lime, therefore I don't need any  more trees that produces limes.

When Logees first started selling them, they were sold as a red finger lime.  Only after they recognized their mistake they changed the name to the correct specie.  I originally purchased a tree from Logees when it was advertised as a red finger lime.  After I found out it was not a red finger lime but only a blood lime I tossed the tree out, as I did not want to waste my time with it,

Lavender87, excellent post.  I never thought about that as a method of leaf identification.
