Boston sits in Lincolnshire and takes its pollen pattern from the East Midlands forecast region. Around 45,300 people live here. Hay fever sufferers should track all three pollen types from March through August.
Tree pollen here is dominated by oak, silver birch and ash, with grass led by ryegrass and timothy and weeds by nettle and mugwort.
Tree pollen typically peaks in April. Grass counts are highest from late May to June. A mix of farmland and woodland produces a long grass season and a sharp tree peak in April.
