In this area we use a fired clay which is sold under the name Hadite. There is another fired clay available in Tulsa, Ok which is about the same thing but red in color and known as 'Lightweight Aggregate'.

The stuff is used in paving roads, making paving stones, a soil conditioner and a meriad of other uses. Check around your area for places that sell large quantities of aggregate but be sure that it is clay and fired to 2000º F. Usually it is sorted into sizes like 0-1/8, 1/8 to 1/4, etc. The stuff in Tulsa sells for about $22 per ton. Take a pick-up truck, fill it up for about $20 and have enough for a year or more.

We mix it with peat and compost in varying proportions depending on the type and size of the tree.
