Many people think that oleander, because it survives some of the toughest environments in the desert, is low in its water use. Yes, it is drought tolerant but not low in its water use. I.e. it can survive without a lot of water but it dies back and drops its leaves when it's threatened like this.

It would be interesting to dissolve small amounts of ammonium sulfate in water (read the application amounts on the bag, divide the amount by 12 and pour the resulting diluent around the root zone (but not the "trunk").
