Depending on the size of the pot, after 1-4 years, the soil goes "sour" for lack of a better description. In the spring, the flytraps produce few leaves, and they're very small. Even with plenty of sun and low-mineral water, the plants refuse to grow like they normally would.
I've had this happen with my own plants, when I lose track of the last time they were repotted. Last year, my Grün and Red Dragon flytraps did this. When I unpotted them, I found that the plants had produced lots of offshoots instead of new leaves. They were planted in a 3:1:1 mix of peat moss, perlite, and coarse sand, in average-sized pots (about 4 inches / 10 cm in diameter) with drainage. They rarely sat in water (only after rainstorms); instead, I thoroughly top-watered them every other day. The trays were always dry by the next watering. I repotted them in early summer, and by the end of the season, they were looking much better.
