Kruševlje was developing very fast during the end of the 18th and at the beginning of the 19th century. More German families were settled down, new houses were built, the streets were lengthened and planted with acacia and mulberry-trees. In 1818 a new, larger church was built, and later a small cemetery chapel. In 1822, in Kruševlje lived 803 Germans and 6 Jews in more than 150 houses. The main occupations of Kruševlje villagers were agriculture (mostly wheat and maize, called "Kukrutz" in Swabian), cattle-breeding (mainly livestock - cows, pigs, oxen, bulls and some poultry), silk-worm raising, later also hemp cultivating and manufacture. Of course, many men were craftsmen (mainly bricklayers, blacksmiths, rope-makers, joiners, etc.).
