I had to update my post (sory for inconvenience):

Please take a look at this Washingtonia (robusta?) that was planted by a nursery that specializes in palms. The red line indicates the level at which it was planted at soil level. Isn't that too deep?

After planting (I undug it. The clear part of the trunk and even the first cut-fronds were entirely under soil level): http://img11.imageshack.us/img11/6220/palms008.jpg

Also the burlap wire and the "plastic rope" were not removed before planting:

It was planted with the entire clear trunk under ground (before the cut fronds begin).
I dug to the roots and they were 13-14 inches deep under ground. The nursery specialist told me this is how they should be planted. Is he correct?

Also they told me to water it every day for 30 days and to water it from top down all the way through the "cut fronds" because they hold water better in those "cut fronds". Is this a correct way to water it?

My opinion is to bury it with the entire trunk above ground. I planted mine then was encouraged by others on Palms North to replant it.

Here is the link discussing planting mine and the pics where i dug them up and replanted.

Thanks :-) I am waiting for that forum's admin to accept my membership, so I will look up your posts and pictures as soon as I'm allowed to.
