Rough lemon (Citrus × jambhiri Lush.)

Rough lemon is a cold-hardy citrus and can grow into a large tree.

The rough lemon is mostly rind, making it less edible than other citrus.

As a result, the rough lemon is mainly used for citrus rootstock,[1] however areas of South Africa and India do consume it.

The mashed up rough lemons would then be put in a furrow, which is a long trench.
