PLUM PRODUCTION IN POLAND
This is expressed in interchangeable occurrence of severe winters (minimum temperature -35°C) typical for continental climatic zone and mild winters typical for ocean climate zone.
The most tender varieties of plums, such as Nectarine, Stanley, Lützelsachsen Frühzwetsche, are usually killed during the severe winters.
Flower buds are often injured due to early spring frosts, which frequently occur in March.
Average temperature of the summer months – June, July, August riches 15°C. Precipitations vary among regions, from 500 mm to 700 mm.
Plums require warm and humid climate.
Generally, Poland’s weather conditions during vegetation period are favourable for growing plums.
Trees are planted on carefully selected sites to prevent winter injuries.
Closed coves accumulating cold air in the winter are avoided, and climatic regions having relatively high winter temperature are favourable
Main plum growing regions are in the south and south-western parts of Poland, having very rich soils and relatively high precipitations, 700 mm and more per year.
Good regions for growing plums are also in the west and north-western Poland, where the severe winters are also in the west and north-western Poland, where the severe winters are not so frequent.
Central and eastern parts of the country have less favourable conditions for plum cultivation.
The average annual precipitation fluctuate between 400–500 mm, and every few years a severe winter occurs what renders plum production hazardous and not profitable.
North-eastern parts of the country are useless for plum cultivation, because of the severe
