71227Is it possible to grow citrus from seed? The quick and simple answer to that question is, “Yes.” After all, many cultivars of citrus were originally bred from other cultivars, and then grown from seed. But of course, this an overly simplified answer to an unrealistically simple question about a surprisingly complicated process. Perhaps a better question is “Should citrus be grown from seed?”.

Almost all citrus are grafted for a variety of reasons. Those that are not grafted are grown from cuttings only because they do not need whatever advantages understock (or rootstock) provides for their counterparts. Either way, they are all cloned by some form of vegetative propagation. This ensures that they are all genetically identical to their parents, without potential for genetic variation.

Citrus have been bred and developed so extensively that most types are very genetically variable. Those that are the most variable tend to produce fewer seeds, and might even be classified as seedless. Those with more seeds are probably more genetically stable. Nonetheless, it is impossible to predict if seed grown citrus will resemble their parents, or be something totally different.

Furthermore, citrus are cloned from ‘adult’ growth that is ready to bloom and develop fruit. Those grown from seed start out with vegetative ‘juvenile’ growth that will not bloom. Juvenile growth is typically more vigorous and thornier than adult growth, and possibly wickedly thorny! Some types of citrus outgrow their juvenile phase quite readily, while others may take several years to do so.

Avocado trees grown from seed exhibit some of the same difficulties. Although they lack thorns, they do grow very vigorously and very tall for quite a few years before they bloom. By the time they develop fruit, the fruit could be too high to reach, and quite different from the original.

Just because citrus and avocados can be grown from seed does not mean that they should be. However, different is not necessarily bad. Many seed grown avocado trees get pruned into

  1. I have often done it, just for experimental reasons. Of course they do not bear fruit but interesting to watch how they grow. I have given up with avocado. The last time I had a centipede infection.

    1. Oh, I remember the centipede. I grew a few avocado trees as houseplants over the years. Two of the best and most productive avocado trees I knew as a kid were grown from seed, including my grandfathers tree that grew so tall that the avocados busted open when they fell. He refused to cut it lower. The busted avocados were good, but the tree was ridiculous.

    1. Oh my! That would be an odd one to grow from seed. Because it is such a direct hybrid (of two distinctly different parents), its seed should be VERY genetically variable! However, the profusion of seed within the fruit suggest the contrary. It would be interesting to see what happens. I do not know how long eitherr of the parents stay in the juvenile stage.

    1. Well, they do not need to be wet straight out of the fruit, but they do not need to be dried either. They are ready to germinate right out of the fruit. It they get too dry, they can actually desiccate, so fresh is better than too dried.
