Citrus stops ripening the day it is picked, but leaving it on the tree until the last possible moment allows them to fully ripen and get sweeter and juicier. Our Pummelos are grown by our partner farm, Noble Citrus, in Winterhaven, FL. They have over 100 years of experience in citrus growing and working with Tree-Ripe allows them to bring you fruit that is left on the tree until the last possible moment. Pummelos are the one of the largest citrus fruit available.
