I don't know whether this is an appropriate question for this NG, but I
don't know where else to post it. If someone has a better recommendation,
I will be happy to take it there.

I have a suspicion that tree roots are stressing the foundation of my
house. However, the symptoms are not constant -- they vary with the time
of year.

My question: In general, do tree roots grow at different rates during
different seasons of the year?

Thank you very much for any thoughts.
