My ponderous lemon has had green lemons since I bought it 3mos. Ago.

Hi Patty. Maybe they have the wrong tag on it, and it is a lime tree instead.
It can take up to 9 months to ripen. I have found that potted trees take longer to ripen than in ground trees. Take one off and cut it open.

Limes are lemons that have not.ripened.
Lemos stay green for a long time. After many many months, they start to slowly turn yellow. You'll be waiting a long time. Make sure the tree gets more than 4 hours sun.
