zone 4/5 inground flying dragon

The Poncirus Trifoliata variety "Flying Dragon" makes an exciting ornamental, and altogether striking addition to the landscape. The dragon like thorns, reaching 4 or 5 even 6 inches in length, produce a contortive growth that gives the tree an outstanding point of attraction for visitors. Some felicitous trimming is required to fully visualize all of Flying Dragons attributes, as it has a tendency to grow in an upright pattern.

So it should be kept in a short bushy form?

No one would have enough ____ (you fill in the blank) to pass through this. I think I might get several for this reason alone.

Why not try something that is somewhat edible, yuzu for example, you would have to cover this in the winter and perhaps add heat...Christmas light for example...

My FD plants should be arriving soon from Stan at McKenzie Farms. Are there any special requirements these plants need in the soil department? I know I will have to amend the hill where I plan on placing these as the ground here is hard and only good for growing headaches. We have a clay based soil thats very fertile but so dense that the worms must use a jackhammer to assist in movement. The hill also has the best drainage. I have access to large amounts of conditioner that I could replace a lot of the existing soil with. I also have a friend with a backhoe if it proves to much for my back. I don't intend to remove the entire hill but rather to dig a big hole in it. I figure the hole will only need to be about 2 or 3 feet deep. Maybe at this depth I will get to something less of a hindrance to roots.
This hill runs along the front/side of our property so all my neighbors will be able to see a citrus tree grow in Arkansas through the winter. It will be a great conversation piece and way to meet neighbors I wouldn't have otherwise had the chance to meet. I have had others stop to admire the citrus plants I have in pots. They have stopped and asked about the care and how its possible to have these plants in such a cold climate and to taste the fruit ( the early birds only ). Many people here have never heard of a Calamondin, Sunquat, or Satsuma. Soon they will be able to see the Yuzu and the FD.

The native home of the trifoliate orange is in northern China, and it is widely distributed, wild and cultivated, throughout that country. It has been largely used for hedges and as a stock on which to bud citrus fruits for cultivation in colder areas. Only you know the true nature of your soil, but if I were to plant the tree in the ground I would not add any amendments to the soil. Trifoliate orange is a good tree for clay and wet soils. However it is poor in soils with high pH, high salinity, also poor under drought conditions.
