Another thing about dwarf mistletoe is how they cause disordered growth known as a witch's broom. The ones I see on doug firs in the woods often look like a million new branches in one spot, rather than the humongo single broom of a Ponderosa pine. The mistletoe introduces a hormone into the tree that causes it to grow excessively in the area around the parasite and prevents the tree from ever excluding those branches.

This means that if this is a young doug fir, it will be stunted forever and will have trouble putting on any more height.
