Here’s Why You Should Add Pinecones to the Bottom of Your Planter

6. Keeps Pests Away

Dry pinecones contain compounds like terpenes and resin acids that repel certain soil-dwelling pests.

While not a replacement for pest control, they can help discourage insects when combined with proper watering.

How to Prepare Pinecones for Planter Use

Before using pinecones in pots, prepare them to ensure they’re clean and pest-free:

Step 1: Collect and Inspect

Gather fully opened and dry pinecones. Avoid sticky or green ones. Shake to remove debris and insects.

Step 2: Bake or Sun-Dry Them

Sterilize them by baking in the oven at 200°F (93°C) for 20–30 minutes or sun-dry them outdoors.

Step 3: Cool and Store

Store pinecones in a dry, ventilated space until use. Avoid sealing them in plastic to keep them crisp and dry.
