Whats a good Citrus rootstock

(1/3) > >>

davidgarcia899:
I have heard that many of the Citrus sold in Miami are on rootstocks not well adapted to our rocky, alkaline soil. I think this true because some of my Citrus are much more needy than others. My Satsuma and Persian lime require half the fertilization that my Meyer Lemon requires. I want to keep expanding my Citrus collection by grafting new varieties on my own rootstock.

So what is the best rootstock for alkaline rocky soil? Or should I just wander Everglades National Park until I find a healthy wild tree.

Wild citrus in the Everglades?  I have never heard of any.  Citrus is an exotic here in Florida.  My understanding is that sour orange provides a decent rootstock for most citrus here.  For a while, when the various viruses were showing their ugly faces, there was talk of using trifoliata and even some tangerines.  This is a question that is probably better left for the experts on a more citrus intensive forum I think.  I have been out of the citrus loop for a decade or more. Hopefully, someone with more up to date knowledge will be able to help you.

Supposedly trees are scattered around the hammocks of the Everglades which depending on the story were either left by Spanish explorers or Seminoles during the Seminole wars.

I think it may be illegal for you to propagate your own citrus in Florida without following the rules outlined here: https://www.flrules.org/gateway/RuleNo.asp?title=CITRUS%20NURSERY%20STOCK%20CERTIFICATION%20%20PROGRAM&ID=5B-62.011

Wow!  That's pretty strict.  Is compliance with this law very high, or do many hobby growers violate it?
