What is Yuzu?
Yuzu is a citrus fruit native to East Asia. It is a crossbreed of a sour mandarin and a wild citrus fruit.
Yuzu is its Japanese name, but it is also known as Yuja in Korea, while the Chinese call it yòuzi.
On average, the fruit is usually 2-3 inches in diameter, slightly larger than a mandarin orange but smaller than a grapefruit.
The skin of yuzu is full of lumps which makes for an uneven texture.
As the Fruit Ripens – The relatively thick skin becomes soft, and the lumps puffy. The skin doesn’t cling to the fruit’s flesh, making peeling exceptionally easy.

You can also easily grow them indoors from its seeds or graft them on rootstocks.
Commercially, grafting is preferred since it has a shorter maturity and yields more fruits.
What is a Lemon?
Lemons (Citrus limon), like yuzu, are native to Asia but belong to the Rutaceae family.
It is a prevalent fruit globally, but its true origin is unclear. With a pH of around 2.2 due to the high levels of citric acid, the fruit has a sour taste.

Citric acid extracts from lemons are used in milk fermentation. Besides, you can use lemons to manufacture invisible ink as well as cleaning and bleaching agents.
How to grow Lemons
Lemons flourish in warm temperate conditions of around 45- 45 °F.
You can plant them indoors or outdoors as long as they have access to sufficient sunlight. Tender lemons trees require frequent watering, especially in the summer months.

Lemons are a hybrid offspring of the citron (crossed with bitter orange).
On the other hand, yuzu is a hybrid of mandarin oranges and papeda, a wild citrus fruit.
As citrus fruits, their growth conditions are almost similar.
However, while yuzu can survive in cold winter conditions, lemons don’t share the same tolerance.
Lemons are extremely sensitive to cold and frost. They go into dormancy when the temperatures drop and may fail to yield fruits if the low temperatures persist.
Yuzu contains hesperidin that prevents inflammation of blood vessels.
The fruit also has and the stronger fragrance compared to lemons which makes Yuzu an effective stress reliever.
