Can canvas fabric be composted after its use in outdoor tree boxes?

Canvas fabric, commonly used in outdoor tree boxes for its durability and breathability, raises questions about its compostability after use. While natural cotton canvas is biodegradable and can break down in compost under the right conditions, synthetic blends or treated fabrics may not decompose as easily. For eco-conscious gardeners, opting for untreated, 100% natural canvas ensures it can be safely composted, enriching soil over time. Always check for chemical treatments or coatings before adding canvas to your compost pile to avoid contamination. Properly composted canvas reduces waste and supports sustainable gardening practices.
