I do a seasonal change of this planter on a regular basis. As many of us, we still like to preserve a little of the fall till Thanksgiving. Here is a thought for that in between time until Thanksgiving. I left springeri (asparagus fern) in the planter from the summer look. It is a good texture mix for fall. I will be taking or cutting it out for the winter look. Berries are from a flowering crab apple tree.
Another way to look at it, when the weather gets colder, the soil gets harder to insert and arrange evergreen branches. Pouring warm water into the soil will soften the soil and make it easier to insert your final trimmings for the Holiday season.
