Thanks Laaz!

Here's a sample of what the site has to say about:

HOW TO PLANT VINE CITRUS TRELLISES


It is important to stress that vine citrus trees are not really vines. Instead, they have drooping branches unable to support themselves. The plants, therefore, have a willow- or umbrella-type canopy. Their branches do not climb like vines nor have special structures to attach themselves to a support structure. The development of citrus trellises, therefore, are quite different than those for grapevines, for example.



Vine citrus trees should be planted at 5 to 7 feet spacing, at about 1.5 feet from the posts towards the interior of the trellis. These posts have to be spaced 10 feet between rows, 5 to 7 feet within post lines, and should be 7 to 8 feet tall.



Vine citrus trees should be conducted as a single or double stem until they reach the fulll height of the trellis. Any lateral branch below this should be removed. These stems should be topped immediately above the trellis and allowed to branch out in all directions. These branches will be supported by beams regularly spaced over the lateral posts. The collection of such willow-type canopies will form the vine citrus trellis. Fruiting occurs along the extremities of the drooping branches and the fruit develop below the foliage with beautiful visual effects.

Today, in addition to the vine orange variety, we have tangerine and lemon varieties with drooping branches thanks to breeding done at Citrolima citrus nursery.

Joe your just amazing on the interesting things you are able to find. Thanks. - Millet

This is pretty interesting as well.

Woodless Buds. Our company developed a new type of citrus budding in order to insure for our plants freedom from the bacteria that cause the disease Amarelinho or Citrus Variegated Chlorosis (CVC). These bacteria live in the plant but are restricted to the wood, and if this tissue is totally removed from citrus buds before propagation, the safety of the whole process is warranted. A method for obtaining woodless buds has been used in our citrus nurseries since 1993. Only the bark containing the bud-eye which will sprout and regenerate a new plant is removed from the budwood sticks. Care must be taken to eliminate wood tissue present in the leaf petiole and thorns adjacent to the buds. In addition, it is important that the buds be totally dormant, to insure that the connection process between the wood tissue and the new buds has not been started. It is a highly technical procedure, yet very simple. Woodless buds are mainly utilized in the establishment of screened budwood increase blocks, from which buds are then taken for nursery propagation. The material in the budwood increase blocks has been selected among the best plants in commercial groves in the last 25 years, and freedom from CVC is triply guaranteed by : 1. budwood heat treatment,
