I highly recommend getting certified disease free wood from the TX Aggies, Weslaco....and it aint just HLB you need to worry about, it's stuff like tristeza and about a dozen other diseases. Since March I've done 37 citrus grafts and recently got 40 buds from the Aggie budwood program and shared some of it with 2 other growers.
http://www.tamuk.edu/Citrus_Center/Budwood%20Certification%20Program.htmlFrom Mark VanNess, program manager, via an email:
"One of the biggest threats to the citrus industry is the spread of disease by movement of plants or receiving budwood from an unknown, uncertified source. We spend over $40,000 annually in an extensive testing program for our Foundation and Scion source trees. All trees are individually tested for Huanglongbing (Citrus greening) , Citrus tristeza virus, Citrus Tatter Leaf virus, Citrus leaf blotch virus, Citrus psorosis virus, Citrus exocortis viroid, Hop stunt viroid, and Citrus dwarfing viroid. Therefore I again encourage you and others to always order from our program. It will be well worth the cost to ensure that you are receiving clean, pathogen-free, true-to-type citrus budwood."My 4 cocktail trees now have these oranges - Hamlin, Marrs, Calamondin, Olinda Valencia and the bloods - Moro and Tarocco. Lemons - Meyer, Pomona seedless (cold hardy into the teens FWIW). Limes - key, limequat (cold hardy substitute) and Persian.
And don't forget the clothespins when doing T-buds.
Trust me, that's the easiest way to really clamp down to insure good cambium contact on wood that's up to 1/2" in girth. Beats the helluva rubber bands and vinyl tape. The Buddy Tape helps cushion any epidermal tissue damage. I remove them after 2 weeks.
