Seed Starting with Soil Blocking


Soil blocking is a seed starting technique that involves using a special tool to create small, compressed blocks of soil that can be used to grow seeds. This technique has become increasingly popular among gardeners and growers because of the many benefits it offers over traditional seed starting methods.

  1. Reduced use of plastic: One of the biggest advantages of soil blocking is that it reduces the amount of plastic waste produced during seed starting. Traditional seed starting often involves using plastic trays and pots that eventually end up in landfills. With soil blocking, however, the blocks themselves can be planted directly into the soil, eliminating the need for plastic containers.

  2. Improved seedling development: Soil blocking allows for better root development and airflow around the roots, which can help promote stronger, healthier seedlings. Because the blocks are small and compact, the roots are forced to grow down and out, creating a denser root system. This can result in stronger, more resilient plants that are better able to handle transplanting.

  3. Space-saving: Soil blocking is a space-saving technique, as it allows for more plants to be grown in a smaller area. Because the blocks are small and can be tightly packed together, gardeners can grow more seedlings in a given space, which is especially useful for those with limited growing space.

  4. Cost-effective: Soil blocking can be a cost-effective seed starting method, as it eliminates the need for expensive plastic containers and trays. With soil blocking, gardeners can use inexpensive soil mixes and compost, making it a more affordable option for those on a tight budget.

  5. Environmentally friendly: Soil blocking is an environmentally friendly seed starting method that promotes sustainability and reduces waste. By eliminating the need for plastic containers and trays, soil blocking reduces the amount of plastic waste produced during seed starting, making it a more eco-friendly option.

Overall, soil blocking is a great seed starting technique that offers a number of benefits over traditional methods. Whether you're an experienced gardener or just starting out, soil blocking is definitely worth considering as a way to improve your seed starting process.
