Storing lemons properly will ensure that they stay good until you need them. This is a guide storing lemons.
I wash and dry fresh lemons. Cut them into wedges and de-seed them. Toss them into a freezer proof bag or container.
Whenever I need a lemon in my drink, I add the frozen wedges. No need to thaw, use them frozen. If you need lemon for cooking/baking, take the wedges out of freezer and let thaw a bit.

Fresh lemons can be stored long term by packing in sand. Just make sure no two lemons are touching.

I have my best results keeping lemons fresh (even halved) by wrapping first in good paper toweling, and then in wax paper, and keeping them in my fruit bin.
