Out of control Yucca

Hi there,

I have a very large indoor Yucca – in fact its grown to be too big!

I read somewhere that they can be cut in half and regrown? Is this the case, and if so, would you be able to give me detailed instruction on how to do so?

Also, are they ok to be kept outside? We live in Mount Maunganui so a warm climate.

Thanks,
Sandra
