Re: Cult: New Club in N. AZ

About 40 yrs ago, the 30 yr average annual rainfall here was around 55 inches. Now it's down to about 45 inches, but we are ~14 inches below <that> for the past 12 months.

So I expect the 30 yr average will soon be closer to half what it used to be.

When we were getting 55 inches of rain/year, established plants didn't need supplemental water.

Some parts of middle Tennessee are still under the worst drought conditions, but it's eased up considerably here.

I haven't used supplemental watering for established plants except for a few clumps of cold climate rebloomers to see if they might rebloom (they didn't) and for plants with maturing pods during the summer. But I don't expect to get those whopping big rhizomes like those that come from the west coast.
