102 tenanted plots, of various sizes from 20 poles to starter plots (but all plots offered for the past two years have been 5 poles). 3 vacant plots, but that's because we need to sort the drainage out in that area first. But a waiting list of 13, plus 5 on starter plots who may be ready for a proper plot and at least one currently with 5 poles who wants to take on another 5 pole plot.
We do have some plots where not all the land is yet cultivated, but only a handful, and if someone is sitting on a large plot and not using it all we apply gentle pressure on them to downsize. That works.
Sorry, can't reduce all that to percentages!
But it does help that we're an independent site and don't have to go through the council for things like this.
