Looks like my S. purpurea needs more space! I just noticed that a couple of it's roots are poking about an inch each out of the little drainage holes of the pot. I know that means it has to be put into a bigger pot... but I have a couple questions...
QUESTION #1: What is the best time of year to repot it?
QUESTION #2: Exactly what kind of soil mixture should I use?
QUESTION #3: What is the easiest and safest(for the plant) way to go about this whole process?
