I have a lot of experience growing arid plants, from lithops to peyote to cacti and succulents too numerous to mention. I'll keep posting tips on the frankincense, combining Arid Lands reply and my own observations.
First, buy coarse sand, or if you're lucky enough, dig some from your garden. I would not repot this sampling in a one-gallon pot, I'm going to repot in maybe a four or five-inch pot. The sampling needs to send out new roots, and a tight container helps this process. Do NOT fertilize. For the first month, water every other day, allowing all the water to drain out. Do not let it sit in a pot in a saucer that holds water. Keep it in the sunniest, warmest place in your home. Protect from night chills if you live in a cold climate by moving it at least two feet away from the window when the sun goes down.
That's it for now. Do you have any questions?
