I think it depends on the variety, some are more vigorous than others. Which varieties did you get?
The varieties growing the best for me are Lemon Merengue, Lemon Zest, Phoenix, and Fruit Punch. Those varieties are growing well, several vegetative flushes, no flowering, all planted this March. The varieties that flower repeatedly are Malika, Carrie, Sweet Tart and Nam Doc Mai
