How long does it take for a pom tree to grow?

This depends on whether you've planted a seed or a nursery-grown tree. Pomegranate seeds sprout easily but it can be another three to five years before you get the first fruits and the tree isn't considered mature until about 5 years of age. If you purchase a healthy and strong tree from the nursery, you may get fruit the same year it is planted, depending on its age at time of planting. Earlier fruit (in the first 3 to 4 years) may not be as large as fruit that grows when the tree is older and it may not ripen sufficiently to be consumed. However, once the tree is established, the good news is that it can live up to 200 years!
