How should I go about removing this plant on a staghorn fern?
Hello! I'm hoping someone here knows about staghorn ferns and can help me. My aunt has had this staghorn fern for over 30 years. Since she and my uncle have gotten older they haven't been able to take care of the yard as much so there's been some overgrown plants. I recently realized that there is another plant growing in the fern, according to google it's an invasive umbrella tree. How can we remove it without damaging the fern, or is it safer to just leave it as it is?
