Homicide

I spent most of my adult years in the Pacific NW where there's 9 months of rain and 3 months of dry.  About 4 days after the rains stopped, everybody was out watering lawns and plants.  Didn't seem like there was such a thing as too much irrigation.
.
Now I live in the desert; very dry, very hot.  Seems logical that you'd have to water the living crap out of everything virtually every day.  Right?  Wrong!  The plants are different, the soil's different, it's a whole 'nother shooting match entirely.  Cacti have attitude: 'Go ahead, dumb ass, water me once a week, see what happens.'  What happens is they quickly become sullen and lethargic.  Keep it up and it's, 'Up yours, sucker.  I'm outta here.'  Game over.  Post mortem: homicide.  Weapon: water.  Perpetrator: me.
.
Homicide victims are not noted for their photogenicity and cacti are no exception.  Pix of the survivors are considerably more appealing.  Here are 3 that have yet to succumb to my ministrations.

Golden Barrel Cactus

Echinocactus grusonii

Tubac Prickly Pear

Opuntia macrocentra/violacea

Century Plant

Agave americana
