Torturing Duckweed

Let’s face it. as much as I love duckweed, I can be very cruel to it as well. I have no problem with putting it through the wringer in an effort to understand its absolute limits in small to medium  outdoor settings. For example, I am currently gazing out at a glass casserole dish sitting on my deck. The container’s surface has a plucky layer of duckweed that currently is a nice shade of green and actually growing nicely. The torture part? It has been 95 degrees F every day for weeks and this lemna is sitting in one inch of water. It is every bit as hot as the air surrounding it. (if not hotter due to the reflection of the glass.) Pure torture. Am impressed.

Be nice to your duckweed in urban gardening settings. Don’t treat it the way I treat mine. Give it several inches of water and keep small containers in partial shade.
