[1][2] The birch is also seen as a symbol of vegetative power, and may be honored with people's hope that it will bring its vitality to the coming season's crops.

Girls bring offerings of fried eggs (a symbol of rebirth) and beer to birches, and speak charms about improved harvest when weaving garlands for the trees.

[1] Some of the rites of green week (like making offerings of eggs and garlands) were thought to placate the rusalki so they would stay away from the village's agricultural fields for the season and not bring them harm.

[2][3] The rusalki are also associated with water and fertility, and so may be invoked during green week in an attempt to bring their moisture and vigor to the fields.

[2] One precaution villagers take during this week is to avoid swimming, because rusalki are thought to live in the water and could drown passersby.
