Answer: It seems to take forever for lemons to ripen, but eventually they do. It's important to wait for the skin to turn from green to yellow because unlike other citrus, lemons will not ripen off the tree. The Lisbon is harvested from October to August so you may have a few more months of waiting before the fruit is ripe. Lisbon has a medium-size, elliptical shape, with a deep yellow, smooth rind that is somewhat fleshy. The flesh is pale yellow, seedless, and is composed of twelve segments.
Enjoy your lemons!
