Do you wait until a lemon is yellow before picking?

Question

Some of my green lemons have burst open and appear to be mature. If picked early, do green lemons ripen or should I leave them on the tree until completely yellow? Some lemons have fallen on the ground.

Answer 1

Slightly green-yellow ones can still be picked and will normally ripen off the tree, provided they are large enough. They should be about 2-3 inches in diameter.
