Yacon growing tips as received from Real Seeds

to this:

One month old yacon plants

in less than a month. Eek. We might have to move house.

We were a bit sceptical about the growing tips (surely you can see why from the top picture) even though Real Seeds has never let us down, but we followed the advice to pot them up right away and as our house is not particularly warm or draft free house we put the pots in the propagator as space was freed up from chillis and tomatoes. As soon as the green tips showed, we moved them out and gave them as much light as possible (as advised by Simon Hickmott’s Growing Unusual Vegetables, a dangerous book to have near an internet connection if ever there was one). They’re now spending daytimes in the greenhouse and nights in the kitchen (who needs work surfaces anyway?).

Three of the tubers actually have two growing tips on them (bottom left plant in the top picture) so yesterday my better half took a division from one of the plants, potting it up on its own, and leaving the main plant in the original pot.  It drooped a little at first but perked up and can only be interesting.  A maths conundrum..if we didn’t really have room for five yacon plants, how are we going to find space for six?…
