Hello! I’ve had this lovely philodendron minima for about a year and a half now and it continues to grow. I added some trellis for it to climb around probably 10 months ago now and it has been happy. I noticed in the past month it has put out 2 of these green growths towards the top of the trellis (pointing at 1 in 2nd photo). Are they aerial roots (or something else?) and it is trying to support itself more securely to the trellis as it gets even larger? It has always popped out new leaves at the very ends of itself so I figured the growths must be for support and not new leaf growth.
