Late spring and early summer are another pollen time. This often happens in May and June. Grasses release a lot of pollen then. Common plants include ryegrass, timothy, fescue, and meadow grasses. Dry, windy days can spread the pollen farther through the town.
Summer also has pollen in Valjevo. It often runs from July into August. Weed plants become important now. Mugwort is one of the main ones. Plantain and nettle can also release pollen. Roadsides, fields, and empty lots may have more of these plants.
Late summer and early autumn can still bring pollen. This is usually from August to October. Ragweed is the best-known plant in this period. It can grow in disturbed places and along river areas. Some other weeds may also release pollen before the weather turns cold.
