[FRUITBOXHERO]

Have a red center lime fruiting for the first time, wondering when to pick them? they are about the size of a small egg right now fell full but firm almost black in color

Someone has to know when they are ready to pick? same as a finger lime?

the sin on most citrus turns color - yellow/orange etc...
usually i think also it gets softer and smells like citrus.

Like most limes I imagine once you have the colour and size you want it would be ok to pick. No idea when the “perfect” time is though. That article mentions different properties at different stages. You can also see what stage they pick them at for commercial sale (on their products page).
