Garden Allergy: Conifer Pollen vs. Compost Mold Spores

UK gardener gets ear swelling near 30-ft conifers and compost heap. Asks if conifer pollen is year-round.

Conifer Pollen

Early spring only (new growth). Once annually.

Compost Heap = Mold Factory

Decay fungi/molds produce massive spore loads. Symptoms match: runny nose, rash, itching, sneezing, wheezing. Peak summer (thawing winter-killed material). Year-round in mild climates.

Solutions

• Cover compost with breathable tarp (allows rain).
• Have non-allergic person turn pile.
• Consider removing heap if symptoms persist.

Conifers unlikely culprit. Compost is prime suspect.
