Oak Tree Seed Drop and Leaf Shed: Normal Cycles

Front-yard oaks drop heavy acorns and brown leaves; back-yard oaks don't. A gardener claims beetles cause defensive seeding and recommends heavy pruning.

Natural Variation, Not Pests

• Acorn crops follow 2–5 year cycles (masting), influenced by weather and genetics—not insects.
• Leaf drop varies by species, age, crown size, and moisture. Winter leaf shed is normal for deciduous oaks.

Do Not Prune for This Reason

Heavy pruning stresses trees. If fertilization is desired, use 10-10-10 at 1 lb per inch trunk diameter, scattered and watered in. Avoid weed-and-feed products near trees.

Your trees sound healthy. Enjoy them.
