Right about now I would welcome a heat wave. We've had cool nights and
rainy days. My pond, partly in shade and 4' deep on one end is 65 degrees.
I suspect the ground has not warmed up. In trying to make a tropical lily
happy I have created a mini pond, 8" deep beside the big one and put in a
submersible aquarium heater set to 75. Just did it yesterday. This am the
temp in the puddle was up to 72.

Anyone else in SW Ontario have low temps???

summer. I had a
couple of thermometers in there at one time but the dogs always managed to
sink
them, eat them, destroy them - you name it.
