Water hawthorn, Aponogeton Distachyos
Hi everyone! Here's a question...I understand that water lilies will go dormant below a certain water temperature. My question is, does the lower water temperature have to be sustained to trigger dormancy, or will dormancy be triggered by a single night (or several consecutive nights) of sufficiently low water temperatures even if the daytime temperatures are warmer? For example, if I had a tropical water lily that needs 70+ degree water in a container pond, and the water reached the 80's fahrenheit during the day but dipped into the low 60's at night, would the lily go dormant because of the lower nighttime temperatures? If the lower nighttime temps will cause problems, are there any reliable ways to keep the water gardens warmer at night? Thanks
