Linda, the crushed volcanic is low in nitrogen, but pretty good in most other minerals....
it is good to add some organics too, to increase the water retention (as strictly cinders is likely to not retain water as well as a soil/cinder mix....) probably do not need bagged potting soil, if you can get soil from any one (even if you do not have a truck, you can always pick up a garbage can or a few 5 gal buckets to haul soil in the car....) There are places close by that have choke soils (esp. most property on the east slope of Mauna Kea & some of the area on the NE slope of Mauna Loa that have a lot of rainy weather (1500'-4000' el.) seems to breakdown the cinders...
Edit to update:
If anyone wants to pick purple sweet potatoes, we will be heading up to some new fields after the veggie swap at Richardsons, around 4 ish at the field (unless we are pulled by the lure of the ocean...)
