24yr Old Split Leaf Philodendron

Question

First, I’m not sure that is the correct name for this plant. I’ve had it for 24 years and I’ve kept it alive by simple fertilizing, watering and decent lighting. It is starting to look sparse. The trunks have over grown the pot and the tips of the leaves are turning brown. I can’t go much bigger in pot size. Any suggestions.

Answer 1

I believe this to be the Tree Philodendron (Philodendron bipinnatifidum)rather than Split Leaf Philodendron (Monstera deliciosa)and it looks like you have a container that will be able to house if for the rest of its life. Once it reaches this size, and maturity, it will only need soil removed and replaced down to about 2 inches each year. I do see signs of overfertilization, and since these are epiphytes (natively, they live in and around trees) they won't require much nutrients to thrive. In fact, less is more, here.

Pruning can be done to larger shoots, as this will force lower shoots to branch out.

Increasing humidity as much as possible will help, as well. Older specimens will appreciate the extra moisture.
