Lemon in a Zone 3 season
Zone 3 gives about 123 frost-free days. Lemon needs roughly 270 days from transplant. That is longer than the outdoor season here, so this one needs an indoor start, and even then it may want a tunnel or row cover to finish.
How to grow lemon trees
Plant in a sunny, sheltered spot once cold nights are over. Where winters freeze, grow it in a pot and bring it in for the cold months. Evergreen and self-fruitful, ripening for months.
