Heavy Acorn Crop: Mast Year, Not Weather Prediction

Why Your Oak Is Dropping Tons of Small Acorns

Oaks have cyclic "mast years" every 3–5 years (varies by species). Large crops require stored energy and favorable spring weather (no late frost during flowering). This year's abundance simply means conditions aligned—it doesn't forecast winter severity.

Species Differences

• Black oak: 2–3 year cycles.
• Chestnut oak: 4–5 years.
• White oak: 5–10 years.
• Red/Scarlet oak: 3–5 years, less reliable.

Enjoy the wildlife show; squirrels and birds will feast. No action needed.
