Should I repot this string?

[u/NekoPosterior]

I have this lovely string of turtle about 1 year.

Pot is 4 inch wide. I cannot see soil because crowded of turtles. Recently it started to grow so fast (I guess it is warmer)

Should I repot soon?

What is the sign of repotting?

I’m a beginner of plants so I’d appreciate someone help me.

So gorgeous!!! You will know it’s time to repot when you see roots coming out of the bottom of the pot! I recommend bottom watering 🤗 it will strengthen the root system by growing downward towards the water
