How Much Cold Temp. Exposure Does A Meyer Lemon Need To Set Fruit?

Question

I’m growing a M/L in Zone 7 so I have to go through some measures during the winter to protect it. I’ve been told that a Meyer Lemon needs a level of exposure to cold in order to set fruit. If that is true; What’s the level and amount (hours, days, weeks) that is needed?

Answer 1

The Meyer lemon does not need chill hours and owners north of zone 9 usually overwinter it indoors.
