Citrus General Discussion / Re: new greenhouse planning
« on: September 23, 2017, 05:40:40 PM »
Mark, I pretty much only grow citrus.  Other then that, I have one fully grown pomegranate tree, about 50+- pineapples and a  variety of tomatoes especially bred for greenhouse culture called Trust..

Of course for citrus trees you don't need pollinators.  To cool my greenhouse during the summer months I use what is call a wet wall.  It works great in Colorado, a state with low humidity.  Keeps my greenhouse around 80-F even on the hottest day.  Cooling a greenhouse during the summer is much more difficult then heating the greenhouse in the winter.

Ulfr, as I believe you are aware, pruning a citrus tree greatly reduces or even stops fruit production.  This is because on citrus,  flowers and thus fruit develop on the new wood.  Pruning eliminates the new growth. What you can do is prune just one side of the tree letting fruit develop on the opposite side, and then prune the other side the following year.  This way at least one side of the tree will always be in fruit.

I know the suggested planting distances of (commercial) Minneola, Navel, Valencia, Lemon, Meyer lemon, Tahiti Lime and Key lime, but not Flying Dragon.  I would expect that Flying Dragon would be something close to a Key Lime which most growers recommend 10-ft apart (will take a long time to grow to full growth).

Citrus Buy, Sell, & Trade / Re: Looking for Citrus Amblycarpa
« on: September 20, 2017, 06:42:51 PM »
Amblycarpa, produces very small sour fruit.   Your tree will flower and fruit when it finely  grows high enough to reach maturity.  Amblycarpa has a long juvenile period so it could take 6 to 10 years before it begins fruiting.  The big thorns are a sign that the tree is still in the juvenile stage.

As Brettay wrote, sour orange is a really great rootstock, if you don't live in an area that is troubled with the tristeza virus disease.  Sour orange is still the number one root stock in Texas.  Personally, my favorite root stock is Flying Dragon.  Most all of my in ground trees are growing on Flying Dragon.

Susanne, never use the word "All" when talking about rootstocks.

I see you use the 100-ft. RootMaker extended rolls to make your pots.

Ilya11 your above post is the Spanish version of the University of Florida's "Florida Citrus Rootstock Selection Guide".  The difference between the two is that the Florida Citrus Rootstock Selection Guide, contains more rootstock varieties.   Susanne, fruit quality is always best on slower growing rootstocks. Invigorating rootstocks such as Rough Lemon, volkameriana lemon, and  Macrophylla, generally produce large fruit with low soluble solids and acid content. Less invigorating rootstocks such as many of the trifoliate orange selections and some of its hybrids (citranges & citrumelos) generally produce somewhat smaller fruit, but with higher SSC and TA.

Much of what you want can be done with citrus trees growing in the ground.  However, it is greatly different growing in a container.  It is true that Flying Dragon is a dwarfing rootstock, but a container is just as dwarfing to a tree as a dwarfing root stock and even more, unless you transplant into a larger and larger and larger container.    Grafting on citrumelo and then putting the tree in a container will take away the rapid growth you desire from a rootstock.  My guess is that much of what you want to know about various rootstocks can be found on the Internet, BUT much of what your looking for will not apply to container culture. The best  information on rootstocks (both commercial and new varieties) can be found on the "Florida Citrus Rootstock Selection Guide", published by the University of Florida, but once again applies to in ground trees, not container trees.

The chances of your trees living very long in Florida is not good.  You MUST keep the Asian citrus psyllids from feeding on your trees, if you don't the chance of them living long is zero.  From the pictures you shown, it may already be too late. If kept outside you could put them in a screened enclosure.

Citrus General Discussion / Re: Pigmented Mexican limes
« on: September 16, 2017, 02:15:22 PM »
Yes, Key lime's juvenile period from seed to fruit is 2-3 years.  If it is a gene that determines the juvenile period of a tree, I wonder if it could be spliced into other citrus varieties that have long juvenile times frames to greatly reduce the waiting time from seed to maturity.

Thanks Ilya for the pictures.  If one looks on the Internet concerning transgenic transfer with the Mexican Lime (Key lime) as the receiving agent, there is a lot of information on various transferred genes, such as the CTV gene to control of CTV virus in the lime..   Gene splicing has unlimited capabilities.

Thanks for the up date.  It is exciting to me and I'm sure the other members enjoy it as much as I.  You and your crew are doing an outstanding job.  You will enjoy that greenhouse for years to come.  Greenhouses really give a break from the winters.  You can go in on a cold snowy day and enjoy flowers, trees, fruit, and the warmth. Thanks again.

Do you rotate the containers so that both side of the tree get some direct sun?

Are  these tree growing in the ground or are they container trees?

Ruby Valencia: An orange with the flavor and characteristics of grapefruit.  A new citrus variety, I would LOVE to get this tree for my collection.

In Michigan you don't have to worry about  Phoma tracheiphila, (which is called Mal  Secco in this country).  In my opinion all lemon varieties derived from the Femminello Comune are good lemons.

Zarafet, I know some people use foil wrap, I have never use it.   Mr. Texas, a member on this form, does a LOT of grafting, it would be interesting to hear his comments.

After the graft is made I just cover the bud with the  parafilm wrap.  The bud will push right through the film.

Citrus General Discussion / Re: Problems with potted citrus
« on: September 11, 2017, 09:14:01 PM »
Your tree's leaf symptoms are showing an iron deficiency.  I notice the trace minerals listed in the fertilizer you are using provides a generous level of iron, which under normal conditions should be plenty iron  for the tree's needs.  However, there is an ingredient in your medium's mix  that stands out loud and clear as a problem, and that is the lava rock (scoria).  Four or five years ago I also tried to grow a container citrus tree using lava rock, and my tree looked just like yours.   Lava rock (scoria) gobbles up the iron that the tree could have used, and an iron deficiency results.   I even tried to add additional iron, but always the tree had a deficiency.  In citrus, an iron deficiency shows up on the tree's NEW leaves, but when the deficiency continues to get worse it will then begin to also show in older leaves too.   You will need to replant your tree into a medium without lava rock.  The peat and bark in the medium are good items, however it would be better if you increase the percentage of bark (PINE) and decrease the percentage peat moss.  Instead of lava you could add a coarse sand or another ingredient as a third ingredient that would also have good drainage properties.  The best to you and your tree.

Citrus General Discussion / Re: clay soil amendments?
« on: September 10, 2017, 09:39:46 PM »
In my greenhouse I have a Dekopon and a Cara Cara growing in raised beds.  The Cara Cara has been planted in the bed a long time .  The tree is now 11 feet tall and 11 ft. wide, so I'm sure the roots have long ago grown into the hard pan soil under the raised bed.   For another citrus tree, I originally dug a hole 4-ft. wide X 4-ft. long X 4-ft. deep in the hard pan (took forever), and filled it with a good soil mixture.  It is also doing good.  The other 5 in ground trees I just planted directly into the ground, and they have grown to be large trees.  So there you have it, I did a lot of the original work, that perhaps I did not need to do.
