Ready to go, when?

I like to bring on the divided Vetiver slips until they 'flush'. That means they send up fresh tillers and shoot out new roots. In the warmer months this usually takes 3-4 weeks.
I've developed a protocol  of dividing the Vetiver into cells. In each cell I make sure there are at least two tillers. Research suggests that division into two tillers ensures a greater survival rate than one.
As well as the tillers (ie: the stems) I always divide by scrutinising the roots.
Our experience has confirmed this enhanced survival rate.
The slips may still be 'bare rooted' but they are ready to go as soon as they are planted.We can also keep our costs down by using this method. .
