Lemon tree Pavlovo

Selected in the 19th century by Russian enthusiasts in Pavlovo, near Nizhny Novgorod, this lemon tree is suitable for growing in apartments.
Whereas a conventional lemon tree won’t withstand indoor temperatures over winter, will lose all its leaves and wither, the Pavlovo does just fine.
Small in size, it can be kept in a pot and will produce lemons even in winter on a veranda or behind a window, without necessarily getting much sun.
The Pavlovo lemon tree is the perfect illustration of the extreme adaptability of citrus trees.
So much so that the Russians are now trying to grow it semi-outdoors, in pits transformed into mini greenhouses in winter.
The fruit is a very good lemon, yellow and juicy.

The Pavlovo lemon tree is not very vigorous but productive, perfect for growing in pots or greenhouses.
It tolerates temperature variations very well, but its resistance to cold is average.
Indoors, it can flower in all seasons with few hours of sunshine. It will then bear fruit and flowers at the same time.

Not suitable for outdoor cultivation in Switzerland.
Grow in pots and keep indoors throughout the winter in a warm, moderately bright spot.
