Citrons are self-fertile and thus do not need to be cross-pollinated. Note that their seeds are monoembryonic.
I have never grown buddah's hand from seed, only cuttings, and you only need one plant to get fruit, but you must pollinate it yourself indoors.
Hi, Laaz. Thanks for the reminder - I had forgotten that Buddha's Hand is seedless. However when I went to The Citrus Industry to get I refresher, much to my surprise, I found it had this to say: I wonder if the seeds in the latter are normal (i.e. viable). Anyone know?
I wonder if one is not a mistake & some type of deformed fruit of the sour orange ? Here is an example... http://albums.photo.epson.com/j/View?u=4214778&a=31269062&p=68374487&Sequence=0&res=high
That's one weird looking sour orange. I found a couple pages with pictures of BHs that match Webber's description: http://www.hort.purdue.edu/newcrop/morton/citron.html The image is about half way down the page. http://www.saalfelds.freeserve.co.uk/BuddhasHandCitron.htm The author's note (far right, under the image) on the variability of the fruit is interesting. Perhaps there isn't a different clone. Perhaps seeds are produced only when fruits develop in this way. The mystery deepens.
There are actually 2 clones to buddha's hand. 1 type with seeds is extremely rare to source, despite buddha's hand could be propagate from cutting easily, the 1 with seed is worth a try because it's a bit different from the 1 with no seed. In terms of pulp size and fragrances, there's a different also in it's outlook
