Slovenia has a very diverse climate. Four main regions can be distinguished. The Alpine region is characterised by alpine climate with over 2500 mm of precipitation, more than half as snow. The central part enjoys a temperate subalpine climate with quite hot summers (average hot month temperatures are around 18-20 °C), well sunshine records and an average of 120 rainy days (annual precipitation 1300-1600 mm). The coastal part of Slovenia has a mediterranean climate with warm to hot and dry summers, mild winters, abundant sunshine and the annual precipitation amounts to 1100-1300 mm. The eastern part of Slovenia is characterised by a moderate continental climate with average air temperatures from 8-10 °C and an annual temperature around 23 °C. In this part of Slovenia areas with less than 900 mm annual precipitation are situated.

Slovenia constitutes of a short coastal strip on the Adriatic, an alpine mountain region adjacent to Italy, mixed mountain and valleys with numerous rivers in the central part and to the east, and a small part of Pannonian lowlands in the north-east. Slovenia has an acreage of 20,256 km2.

Agriculture represents about 6% of the national income. Within agricultural production horticulture covers around 17%, but this percentage is raising yearly.

There are 5000 ha of intensive orchards (mainly apples, pears, peaches, olives and strawberries). By cadastre there are also 31000 ha of extensive old orchards. The acreage of vineyards is 25000 ha. Annually 3,000,000 wine grafts and 700,000 maiden fruit trees are produced. Vegetables are grown on 11,500 ha of which 1000 ha under cover. The yearly production of ornamentals is about 30,000,000 trees, bushes, and cut and pot plants.
