Roots belong to the bottom portion, and not to the top portion, whether they are showing a little or not.  As far as cutting the roots, its up to you, its your tree, I wouldn't.

I yearn for the old days when white grapefruit where king.  I like white a great deal more then the reds.  Red have lost the bite of a white grapefruit, and they are much to sweet for what grapefruit stood for.   Thank to God I planted a seedless Marsh in the ground 3 years ago.   Last year the tree had two fruit, which were wonderful when left hanging on the tree until March.  This year the tree is producing 7 fruit.  Think next year as a 4 year old tree perhaps 15 to 20????   The trick is to leave them on the tree until March or April.  Grapefruit aren't supposed to taste like candy.

100% of my container grown trees are growing in Air Root Pruning Containers.  I personally believe that they are the finest containers to grow a plant in. Kvetch , its your tree, and you certainly can grow the tree anyway you wish.  One comment on the fertilizer.  If you wish to grow a container tree using organic type fertilization, its your choice.  A good conventional fertilizer with high nitrogen and potassium will be much better for your tree, but it your choice. Lastly, I would strongly recommend that you do not prune any of the tree's roots.  A citrus tree is a balance of the top foliage portion and the below ground root structure.  During the first years, there is no need to cut/prune all, or any part of the tree since research has shown that any cut to a young tree reduces root growth.  This is due to the equilibrium between foliage and root system.   A citrus tree is a biological unit.

Thanks for posting additional pictures of your tree.  Your tree looks healthy.  New leaves start out lighter green and will naturally darken up in several months . I don't see much wrong with the tree.  The few leaves that your concerned about that yellowed is normal.  They were just old leaves that have lived their life.   If I understand correctly, you have been digging some medium off of the top.  Your tree now seems to be showing quite a lot of root structure now exposed.    All in all your tree looks fine and healthy.  I agree with Susanne, it would be best to change your fertilizer.   Find one higher in nitrogen and potassium, and lower in phosphorous and containing trace minerals.  I use 25-5-15 W/TM.

As Citradia  wrote it could be many things.   I'm not surprised that you are unable to find a graft union, because I doubt that your tree is a grafted tree.  Meyer lemons root extremely easy from cuttings, therefore a huge number are raised and sold as rooted cuttings instead of a grafted tree.  Trees grown from rooted cutting do not produce long tap roots, that strongly anchor the  tree to the soil.  In areas like Florida, even in ground growing younger rooted cutting propagated trees are commonly blown over from strong winds.   This is what happened to your tree, and it more than likely has some root damage from torn roots.  Do you know exactly how old your tree is, and how long it was at Record Buck before you purchased it?  Citrus leaves have a life span of approximately 16 to 24 months.  When a citrus leaf can no longer pull its weight, the tree removes the nutrients from the old leaves, and disperses them to the rest of the tree, then discards the leaf, doing so the leaf turns a yellowish color.  These older  leaves are of course the bottom leaves on the branch.. The  pattern shown by your photo has such a look.  I have quite a few citrus trees, both in the ground and container trees.  At this time of year many of my trees have leaves showing the exact leaf pattern.   Lastly it is your tree, and you can certainly grow it as you wish.  However, citrus are HEAVY feeders and do much better where fertilizer with conventional fertilizers, than organic types.  Keep an eye on your tree, and if thing get worse we'll need a follow up.

Citradia, see there you go,  I didn't know it worked for apples and pears.

Citrus General Discussion / Re: Using neem leaves instead of oil
« on: July 20, 2017, 11:43:56 AM »
Neem works well, but I don't like the smell.  I always use Ultra Pure horticultural oil to control aphids, mealy bugs, thrip and scale.

Ilya11  I'm really surprised that the Valentine pummelo developed by the University of California at Riverside has already been released to Europe. 

A day time temperature of 78, and a night temperature of 60 should be sufficient for Valentine.

Your grafts really took off.  You should have fruit in a couple years.

Any temperature  above the absolute 54.5-F would be enough to keep the tree growing.  Pummelos, such as the variety Valentine, require high heat requirements to mature. The heat units from temperatures such a 60 to 70 would take the fruit a very very long time to mature, and at those temperatures the fruit would produce very little soluble solids (sugars), and if it ever turned a mature coloration, the fruit would probably be very bitter (sour).

By United States Department of Agriculture regulations any citrus variety that produces 6 seeds or less per fruit, can be legally called, and sold as a seedless variety.  As SoCal2warm wrote, recently radiation is now commonly being used to change seeded fruit varieties into seedless varieties.

Is it possible - yes.  Is it probable - probably not.  If you can provide the light, and keep the temperatures around 83 or so then  maybe.  Eventually, you would need a rather large container.

Valentine pummelos do have large leaves.  Nice to hear everything is going great with your trees.

More Asian Citrus Psyllid found in California.  During a routine sweep on July 6, agriculture officials in Placer County found one of the bugs linked to the mass depletion of citrus plants in Florida. The Asian Citrus Psyllid was found in a residential back yard in West Roseville.

Lemons are one of the citrus varieties that come true from seed.

Are those rooted cuttings, or seedlings?

As Susanne wrote it is probably a manganese deficiency.  A manganese deficiency shows on the newest leaves having green veins WITH green border areas to the side of the veins, on an otherwise yellow leaf.  Manganese deficient leaves remain NORMAL SIZE. Manganese deficiency commonly shows up when the tree is flushing new growth, but not always.  I can't see your picture all that well, so I will also mention it might be a zinc deficiency.  A zinc deficiency looks very much like a manganese deficiency --- green veins with a green border area to the side of the veins, and also showing on the newest leaves, but in a zinc deficient leaf the leaves are substantially dwarfed in size.  You can foliage spray with  a dilute solution, or apply the fertilizers to the root zone, using manganese sulfate or manganese nitrate to correct the manganese deficiency.  The same procedures using zinc sulfate should take care of a zinc deficiency.

Susanne is correct, it illegal to send bud wood into the USA from a foreign country.

Citrus General Discussion / No White Grapefruit
« on: July 11, 2017, 05:54:55 PM »
For the longest time I have not been able to purchase a white grapefruit at the supermarket.  All they ever have any more is red.  Good thing I have a Seedless March grapefruit planted in the ground.  Presently it is still a semi-small tree, which does not produce a large quantity of fruit.  In just a couple years the tree should really pick up .

Blood Clementine from seed to fruiting 3 to 5 years. 

If the new leaves are growing out without the brown center vain, but rather look normal, I would not worry about it much.
