Re: CULT:Rain vs. Watering

From: "Patrick Orr" <PatrickJOrr@hotmail.com>

We have to be kind of careful out here in Phoenix when it rains in the summer.  That rain water gets trapped in the fans and combined with the heat out here we sometimes get, you could have steamed rotted irises in no time.
 
I like to cover the irises in the dead heat of summer with shade cloth for protection (although it is really not necessary), but if it is going to rain I remove the cloth because it will trap the moisture in and around the iris. I have seen where water remained in the fan for up to three days after a summer rain before evaporating.  This is the time of year we withhold water so the rhizome will toughen up before dividing and wont be so "green".
 
Since I am trying some rebloomers for the first time this year, I won't be doing this method with them obviously, but I understand they are more resistant to rot than once bloomers???

Especially if it's from a thunderstorm, rain water will have a little
nitrogen in it, which may help.

Or maybe the cooling of the weather front may be good, or the winds, or
the higher humidity during the rain.

My guess is that this is not the reason.

But many of us have noteds the effect: rain is better than watering.


Gerry, looking forward to rebloom by Keppel's Lovely Dawn
