I expected that, but am surprised it was enough to make a difference. The pots only get morning sun, the field is exposed all day, & is in raised rows. Basically, the pots pretty much track air temperature. So I doubt aluminum foil would help much Betty.
I'm toying with the idea of putting the pot inside a larger pot, then adding a few chunks of dry ice. See if it likes the extra CO2 while chilling ;-) If there's a place in town where I can get a few small pieces, I might give it a try. Maybe put the dry ice in the bottom of the bigger pot, then a layer of mulch, then the iris pot, maybe pack mulch in a layer all the way around between the two pots. Just for fun ;-)
Chuck, have you done comparisons of pot and field temperatures? Just wondering how big the difference is.No thermometer in the field rows, but I am curious to check to see what it is.
But being close to the house and under high canopy may have kept pots warmer at night during June when it was fairly cool here. I've always assumed it was night temperature (i.e., lows) that provide the trigger for "summers" here.
I've been running the sump pump 1 1/4 hose from the spring there since last night, so it's probably cooler now than it was.
