Do potted sagos not cone

[N8ALLRIGHT]

Ok so I'm sure they do, but my wife has had these pre me, probably 22 years or so. We've got 4 of them, probably 8 in diameter caudex, ranging from 12"to 15" in trunk height. Never coned, they're inside 4 months out of the year due to our zone. I'd think they're old enough and big enough. Is this just due to being in a pot,4 months of marginal light, couple of winters being neglected, not enough fertilizer,all of the above? Repotted this year with coir, garden soil,  turface mix.and a little dynamite. They look great otherwise.TIA

I have several coning size Revoluta, but all are at least 3' of trunk.  I really don't know where they start coning, they might not cone until they are 2' or more of trunk.  That's just a random guess though, since I don't have any coning ones in the 1-2' trunk range.

22 years for a Cycas revoluta and still not seeing cones is a long time.  While it doesn't matter that they are in pots, the climate and limited light probably are the driving factors.  By the way, if they are female plants they will never produce a "cone" as Cycas genus females only produce megasporophylls which aren't really cones.  Male Cycas revoluta will produce a true cone and in a distant way, the structure formed by some megasporophylls might be conical in shape, but a layperson probably wouldn't describe them as cones.  Since the odor or many male cones can be a little overpowering and unpleasant, consider yourself lucky to have been spared thus far.  Particularly if you are bringing them inside.
