Beginner Gardening: Should I Transplant This Succulent?, 1 by tapla

No. We only need to consider the degree to which roots are congested, and act to repot or pot up at the most appropriate time. We can grow very large plants in very small pots, if paying proper attention to the roots. Conversely, we can also grow very small plants in very LARGE pots if the soil is appropriate - that is to say, if the soil is porous and free draining enough that it supports little or no perched water. When it comes to choosing appropriate pot size, the current size of the plant and the size of the root system in particular, only need to be considered if you're using a water-retentive soil. When using a soil like the gritty mix, seen below, there is no upper limit to pot size and minimal pot size should be large enough to comfortably accommodate the size of the current root mass plus at least 1 year's growth (assuming you're repotting at the appropriate point in the growth cycle - usually very late spring [just before Father's day] to mid-July).
