Q.Two Mexican limes, only one is blooming
I purchased 2 Mexican lime trees last year. They are both potted and kept indoors through the cold months of our Nebraska winter. They’re both receiving the same care, same amount of sun. Only one of the two are blooming. Does this variety have males & females? If not, why would the one not bloom? They appear to be the same age.
