The citrus nursery industry is undergoing a lot of changes as HLB continues to cause pressure. Growers are having to replant their groves in order to keep their operations economically viable. This is causing an increase in the demand for young citrus trees, especially for the new, more HLB-tolerant rootstocks and varieties. These new varieties are mostly propagated through cuttings and tissue cultures, as opposed to the more traditional method of propagating from seed. Phillip Rucks, of Phillip Rucks Citrus Nursery, commented on how his company is adapting to this new paradigm shift.
