Split-leaf philodendron question
I have a large split-leaf philodendron. Its about 7 feet wide and 3 1/2 feet tall--I just love it. Its a large plant and in a large urn-type pot. It's wintering over inside but will be moved (not too easily!) outside when it gets warmer here. My question is...its been putting out roots that grow outside the pot. I'm not sure if they are air roots or just normal roots that have nowhere to go. The roots are crawling over my living room floor like snakes (5-6 feet long). I want to know if it will hurt the plant if I cut them off. There are only about 3-4 large ones. But I surely don't want to do anything that will harm my beautiful plant.
Thanks to anyone with experience in these who might have a suggestion.
