desert+tree+watering+schedule

As I know it, the "gallon" of a plant or bush has to do with the container size, not the amount of water needed for the plant.

1, 3, or 5 gallon bushes can be bought at most big box stores. Has to do with the size of the plant. This has nothing to do with watering.

As usual, Dale, I have no idea what you mean.

I presume, Punk, the container for the root

Aha thanks Punk, then I suppose what I need to know is the approximate size of a typical tree whose root fits into a 15-gallon pail

Well, join the crowd. I'll try to clarify

'
get a typical figure yields anythin' from 4 to 60 gallons/weekWhen I Google the subject I am confused: Depending on the report, I conclude that the typical desert tree requires anywhere from 4 to 60 gallons of water a week. Therefore I had hoped that someone with experience with typical desert trees might shed some light on the subject

I should 'splain, Key, at 86 possibly w/ Alzie's I might misread

You bought a tree that was in a 15 gallon container. That has nothing to do with watering.

What kind if tree is it? You are more likely to get your question answered just by identifying the tree.

My reasoning was, the bigger the container, the more water might be reqd

--- " '[mine mostly Ariz Cyp]' "---

Ariz = Arizona, a US State
Cyp = Cypress, a kind of tree

Like I said, Unk, my most sincere apolos from this poor slob at 86 with apparent Alzie's

Also I get responses like that allatime. Incidentally, having worked at Googlin' it for hours, I've somewhat tentatively decided that 4 gallons/wk 'way too low; but that 60 gal/wk maybe 'way too high

Selecting one of about 3" dia we'd suppose at 10/gal/wk/in., then 30 gal/wk. However, w/ two 2-gal/hr drippers [watering once a week; there's not much choice in the matter] for two hours gives only 8 gal, 'bout a quarter what the 'sperts would have. Yet the li'l fella looks perfectly healthy

So my wild guesswork would seem to indicate that maybe the 'sperts are overdoin' it by a factor 'v't'least 4
