so my cutting survived the winter without going completely dormant. It had three leaves left. Now I am seeing a new growth and new leaves are coming out. How do I know when to re-pot it and when to start to water/fertilize? Also, WHAT fertilizer I should use? Our summers get super hot, especially on the south and west facing sides of the house, so I am thinking about the larger pot (maybe the black one from the pic?), so I could move it around.
