Thanks, Lynn. In my neighbor's yard, where the tree got transplanted to,
we like to do things the hard way. No stinkin' hoses with tap water for
us. The water must sit out 24 hours so the sun can burn the chemicals
out.

To really make sure you burn the chemicals out you may want to let it
sit for couple of weeks. The particularly nasty chemical I have in mind
is dihydrogen monoxide, which can cause fatal breathing afflictions.
Hope that helps.
