I mentioned that our trees are usually in full leaf by the first week of May. One of the things that does is change the light inside our house.
Obviously this photo was taken on one of our innumerable rainy days. But you can pretty much tell that even on a sunny day, this window is not going to get much sun. Why am I even making an issue of this?
This is what’s in that window. And from October until just about now, it’s fine. Now I am praying for some warm weather so that I can get all these (or most of them anyway) outside for the summer where they will be much happier.
So if your house plants suddenly start looking a little peaked, take a look at what’s happened to your indoor light. Perhaps, like mine, it’s gotten a little shadier than your plants care for.
Gardendaze 
Various architecture makes various types of shade. Ranch houses with big eaves shade windows more than Spanish style houses that lack eaves. Also, the shade of low trees does not change through the season as much as the shade of tall trees, like redwoods.
Very true. I didn’t address that at all but there homes, particularly in the south, that were built to maximize shade and cooling.
I am just glad that I didn’t believe anyone when I moved to the frozen north over 30 years ago. I was told that we didn’t need air conditioning here. I was skeptical then and it’s absolutely untrue now. We certainly don’t need it as much as many places (and as you can see, I have planted for cooling–I planted that tree on the south side of the house to shade it in the summer).
But of course there are those brutally humid days and nights. Ah well. That’s what seasons are all about.
