FAQ
Frequently Asked Questions
Yes, the fruit is edible and very acidic, but it is primarily grown for agricultural purposes, such as rootstock, rather than for the commercial fruit market.
It is highly unlikely. Rough lemons are not typically sold for fresh consumption; you are more likely to find them at a specialty nursery or in a citrus-growing region.
Their primary use is as a rootstock for grafting other, more commercially desirable citrus varieties, as they impart hardiness and disease resistance.
No, it refers specifically to the physical texture of the fruit's thick, bumpy rind. The taste is sharply acidic, similar to other lemons.
