Visit Dragon's Backbone Rice Terraces in October

Hi, I have read somewhere that October is a good period to visit the rice terraces, but before October 15th because after that time the rice has been harvested and there is nothing left to see...
Can any body confirm?
I can do it only on October 22nd this year and I am afraid it will be too late.
The good thing is that since I have only one day free in Guilin, I can still do the Li rIver cruise :)
Thanks
Mark
