Citrus Not Quite Reincarnated

   
 Here we are, November already!
     November is when your fruit will really start to take off and turn ripe.
That is why the Southeastern Cold Hardy Citrus Expo is usually held this month. (More on that in a minute)

     I stressed this somewhat in the earlier part of this year, but, it might not have reached all of the proper folks and it is coming to light now. I have had an increasingly alarming rate of phone calls and e-mails talking about how their citrus tree died back this past January, but it has come back stronger than ever, it just didn't flower, what is wrong? In almost every case, except a couple, it is because the tree that was once there is no more, the rootstock has taken over.
Rootstock Suckers
     Rootstock, in case you didn't know, is what a "good fruit" is grafted onto. The rootstock of choice is used depending on what the grafter is trying to overcome. Some of them are used to dwarf the tree, others are used for nematode resistance, some are to deter different diseases and many other things. Not all citrus is grafted, but many are.
     I also heard from a couple of folks that their tree came back, it was a grapefruit, but this year the fruit is so much smaller, what happened? Again, the rootstock has prevailed.
Poncirus trifoliata
     Typical rootstocks that are used are mainly trifoliate hybrids and have the "tri" number of leaves. There are other rootstocks out there, Cleopatra, Bitter Orange (a.k.a. Seville) and many others that do not have the "tri" leaf. Those can be a little harder to discern from the original tree.
Swingle Citrumelo- Hybrid cross- Citrus paradisi x Poncirus trifoliata
     If you are uncertain as to what your tree might be now, feel free to e-mail me some pictures of the leaves, I can usually tell from those.
     Of course, if you have never seen how many different leaves there are on different citrus trees, take a look at this.

     You can click on the picture to make it bigger.     Here is the key to what each of the 37 different leaves is:
a 'Nasnaran' mandarin (C. amblycarpa), b 'Galego Inerme Key' lime (C. aurantiifolia), c 'Narrow Leaf' sour orange (C. aurantium), d 'Bergamot' orange (C. bergamia), e 'Taiwan' mandarin (C. depressa), f 'Mauritius papeda' (C. hystrix), g C. hystrix hybrid, h 'Variegated' true lemon (C. limon), i 'Talamisan' orange (C. longispina), j 'Etrog' citron (C. medica), k 'Variegated' calamondin (C. madurensis), l 'Chinotto' orange (C. myrtifolia), m 'Star Ruby' grapefruit (C. paradisi), n 'Cleopatra' mandarin (C. reshni), o 'Fairchild' tangerine-tangelo [C. clementina 9 (C. paradisi 9 C. tangerina)], p 'Szincom' mandarin (C. reticulata), q 'Valencia Trepadeira' sweet orange (C. sinensis)\, r 'Variegated' sweet orange (C. sinensis), s 'Jaboti' tangor (C. sinensis 9 C. unshiu), t common ‘Sunki’ mandarin
