The citrus i grow that end in quat bloom like crazy within a few months of growing them. Quats and Quat hybrids are quick to bloom and continue to bloom. Many grapefruit I have grown bloom once a year every year for years. Oranges bloom yearly once they hit the age to do that. Grafted trees bloom faster if grafted from mature trees. In this situation it’s a quat hybrid and is blooming like crazy and will continue to do the same all its life. Nippon quat hybrids etc bloom quickly also
