Do pencil shavings help plants grow?

Pencil shavings can provide some benefits to plants, as they are made of wood and can contribute organic matter to the soil as they decompose. However, they have little nutritional value on their own and should not be relied upon as a primary source of nutrients. If used in moderation, they can improve soil structure and drainage, but it's best to combine them with other compostable materials for optimal plant growth.
