[CANUFNET] Water retention and tree planting

MessageIan:
I've heard a lot of positive comments regarding the use of Gator-bags. They are a reusable, durable plastic container that slowly releases about 20 gallons of water over a long period. The City of Calgary did a study, and now uses them exclusively, as they worked better than any soil amendments.

  I grow trees in a semi-arid area (on average, 11 inches of rain and 4 inches of snow per year)

  One of our biggest challenges with tree planting is water.  Many of our plantings are irrigated and we also water with a truck, but we are trying to reduce water usage.

  I've looked at various products in the past for improving the water retention in the planting hole.

  Has anybody tried using various soil amendments, such as "Water-lok", clay, or even just compost or organic matter amendments, and can you pass on your experiences?

  thanks, Ian
