Can You Compost Sweetgum Balls? Only in a Hot, Patient Pile

Sweetgum balls—the spiky, woody fruits of the sweetgum tree (Liquidambar styraciflua)—are a landscape nuisance. They can be composted, but only in a consistently hot pile (100°F+/37°C+), turned and watered religiously. They break down very slowly.

If You Try It

• Run a hot pile; monitor temperature.
• Turn and water regularly.
• Be patient—months to years.

Upside

The resulting rough compost deters slugs, rabbits, and other pests with its prickly texture.

Most gardeners find removal easier than composting. But if you’re committed to zero waste, a hot pile can eventually handle them.
