You should be fine in the coming years. Just make sure to fertilize regularly and keep the plant healthy. The reason you did not have good crops the past few years is because plants, like animals, have to reach maturity before they can produce fruit. The first few years most fruits are planted, the plant is not mature enough to make seeds (which is why they make fruit). Instead, it focuses on growing leaves and roots. But, yours has now reached maturity (as told by the good crop) and should continue to produce well as long as it stays healthy.
