Are these reliable? Will they continue to bear fruit although there isn't both genders? (I am new) what is your take?

It says self pollinating so a second tree is not needed. Only one i have is a meyers lemon and can confirm it is self pollinating.

4" pot is small. Citrus must be the new rage cause even walmart sells meyers lemon and various citrus in larger pots, big enuff to fruit.

Besides myers lemon i would look for satsuma citrus. Its one of the cold hardiest. It still needs protection but it takes cold better than other varieties.

i agree those will take a long time to fruit best to get a 5 gallon size from somewhere near you if possible
