Benefits of Soil Blocking for Seed Starting (1 min read)

As a flower farm in Texas we've tried many different seed starting methods. Through trial and error we've found that soil blocking is a vastly superior technique compared with the traditional plastic seed starting trays. 

   One of the main benefits of soil blocking is that it allows for more efficient use of space. Traditional seed starting methods, such as using trays with individual cells, can take up a lot of room in a greenhouse. With soil blocking, the seedlings are grown in small blocks of soil, which are then stacked on top of each other. This allows for many more seedlings to be grown in a smaller area.

   Another benefit of soil blocking is that it helps to reduce the need for transplanting. When seedlings are grown in individual cells, they must be transplanted into larger containers as they grow due to the root system of the plant becoming root-bound within the small growing area. This can cause stress on the seedlings and can lead to transplant shock. Additionally, the roots within the small cells will grow in a circular pattern, inevitably choking out the plant's ability to absorb nutrients. With soil blocking, the seedlings are grown in blocks of soil that allow the roots to spread more naturally and in turn can be more successfully transferred to larger containers or directly into the garden. This eliminates the need for transplanting and helps to reduce stress on the seedlings.

   Soil blocking also helps to reduce the risk of disease. When seedlings are grown in a tray with many cells, it is easy for disease to spread from one seedling to another. With soil blocking, each seedling is in its own block of soil, which helps to reduce the risk of disease.

   In addition, soil blocking allows for better control of moisture and temperature. When seedlings are grown in a tray with many cells, it can be difficult to keep the soil at the right moisture level. With soil blocking, the small blocks of soil can be easily misted or watered, which allows for better control of moisture. Soil blocking also allows for better control of temperature, as the small blocks of soil can be easily moved to different parts of the greenhouse to ensure the seedlings are getting the right amount of light and heat.

   Overall, soil blocking is a technique that offers many benefits for starting seeds. It allows for more efficient use of space, reduces the need for transplanting, reduces the risk of disease, and allows for better control of moisture and temperature. If you're looking to start seeds this season, consider giving soil blocking a try.
