Yes, seedlings can be effectively protected using biodegradable seedling nets or covers as an alternative to traditional non-biodegradable options. These biodegradable materials, often made from plant-based polymers or natural fibers, provide the necessary protection against pests and environmental stressors while also decomposing naturally after a certain period, reducing waste and environmental impact. They offer a sustainable solution that supports the growth of healthy seedlings without compromising the integrity of the ecosystem.
