What are the best fabric choices for rooftop or balcony flower boxes?

When selecting fabric for rooftop or balcony flower boxes, durability and functionality are key. The best options include:

1. Polypropylene Fabric: Lightweight, UV-resistant, and breathable, ideal for drainage and root health.

2. Geotextile Fabric: Strong and permeable, perfect for preventing soil erosion while allowing water flow.

3. Burlap: A natural, biodegradable choice that offers good aeration but may need replacement over time.

4. Recycled Plastic Fabric: Eco-friendly and long-lasting, great for sustainable gardening.

5. Canvas: Sturdy and water-resistant, suitable for larger planters but requires proper sealing.

Choose fabrics based on climate, plant type, and maintenance preferences to ensure thriving rooftop or balcony gardens.
