Q.lemon fruit color
My parents in mid Florida have an in ground lemon tree facing the west and getting almost full day sun. Bought last year, it is fruiting this year with full size lemons that are now 50% yellow. Must the fruit be left on the tree to continue ripening? Concern is an early frost could damage the fruit.

They will continue to ripen, but you will be sacrificing some flavor if you pick them early. A light frost should not cause harm to the fruit, but if you expecting a heavy frost, it may cause some damage to both the fruit and the tree.
