Seeds and Soil Blocks: A Perfect Match
When placing seeds into the prepared soil blocks, consider the seed size for appropriate block depth:
Small Seeds: Such as lettuce or herbs, can be sprinkled on the surface and lightly pressed into the block.
Larger Seeds: Like tomatoes and peppers, should be sown one to two per block, planted at a depth twice the seed’s diameter.
Soil blocks should be kept at the correct temperature to facilitate germination, typically between 65-75°F (18-24°C). Observe soil humidity—the blocks must stay moist, but not waterlogged, to ensure successful germination and seedling vigorous growth.
The Soil Blocking Process
The soil blocking process is an efficient way to start seeds by creating a nutrient-rich, self-contained soil environment for seedlings. This method eliminates the need for traditional plastic pots, reducing waste and minimizing transplant shock.
Creating Soil Blocks
To start, one needs a soil blocker and a fine-textured, moist potting mix. The mix should be wet enough to hold together when compressed but not so wet that water easily squeezes out. The ideal consistency allows the block to maintain its shape while retaining adequate moisture. Using the soil blocker, the mix is firmly pressed and then ejected to form uniform blocks. It is vital to ensure that there are no air pockets in the blocks which could deter root growth.
Sowing Seeds in Soil Blocks
Once the blocks are formed, seeds are sown by making an indentation with a dibble or similar tool, at an appropriate depth suggested for the specific seed type. Generally, seeds are planted at a depth twice their diameter. Larger seeds may require larger blocks for adequate root development. It is recommended to sow 1 to 2 seeds per block to avoid overcrowding. After sowing, gently cover the seeds with additional soil mix.
Maintenance and Care for Seedlings
Seedlings in soil blocks require consistent moisture; bottom-watering in bottom trays is efficient to ensure even water distribution without disturbing the seeds. A heat mat can be used to maintain a stable temperature, promoting germination. As seedlings grow, it is important to monitor moisture levels and gently water to keep the blocks intact. Preparing for transplanting involves hardening off seedlings to outdoor conditions to reduce shock and ensure successful growth when moved to a garden or larger container.
Growing and Transplanting
Using a soil blocker machine enhances the efficiency of starting seeds and ensures successful transplanting. The following subsections delve into the specifics of nurturing healthier plants, the process of transplanting seedlings from soil blocks, and the timing and techniques crucial for transplantation.
Nurturing Healthier Plants
Soil blockers allow seedlings to develop without becoming root-bound, promoting a robust root system. As seeds germinate and grow in the soil blocks, the exposed sides of the block cause the roots to air prune, ceasing their outward growth and encouraging lateral development. This is critical in nurturing healthier plants which, when transplanted, recover quickly and continue growing with minimal transplant shock.
Transplanting Seedlings from Soil Blocks
When seedlings in soil blocks reach the appropriate size, they can be transplanted directly into a garden bed or larger containers. The soil block acts as the container, and since the roots are air-pruned, there's minimal risk of disturbing the root system. This process should be as gentle as possible to retain the integrity of the growing medium around the roots.
Prepare the new location: Whether it's a bed or a pot, ensure it's ready to receive the seedling block.
Popping the block out: Handle the block carefully, supporting it from the base to avoid squashing.
Placement: Make a space just large enough for the soil block and nestle it in, filling any gaps with soil.
Timing and Techniques for Transplanting
Timing is crucial for the success of transplanting. Transplant seedlings once they have developed true leaves and before they become too large for their blocks, to reduce stress. Monitor the growth of your seedlings, and aim for a period where the weather is mild, as extreme conditions can exacerbate transplant shock.
When to Transplant: Look for weather forecasts that indicate a period of mild weather and transplant in the late afternoon to avoid midday heat.
Watering Before Transplanting: Ideally, water the blocks thoroughly one day before transplantation to ensure the blocks holds together and the plant is well hydrated.
By following these specific steps and best practices, gardeners can improve the success rates of their transplanted seedlings and encourage the growth of healthy and productive plants.

The usage of a 2 inch soil blocker ensures that larger blocks can be created for transplants requiring more space. Adding microbial inoculants can also promote healthier and resilient seedlings.
To prevent issues such as air pockets, which can dry out seeds, it's essential to achieve a consistency akin to wet cement when preparing the soil mix. This will allow the blocks to hold together without crumpling, yet still provide enough moisture for seed germination. Achieving the right moisture level is key; the mix should be wet enough that when squeezed, a few drops of water are released, ensuring that the soil blocks retain their structure while providing the necessary hydration for the seeds.
Troubleshooting Common Soil Blocking Issues
Gardeners may encounter challenges such as blocks falling apart or seeds failing to germinate. A common cause is an incorrect moisture level; the soil mix may be either too dry or excessively wet. Consistency is paramount — the mix should be uniform and moist throughout. When using homemade soil blockers, ensure they are compact and create a well-defined shape, mimicking commercial block makers' efficiency.
Another issue can be small seedlings outgrowing their mini soil blocks, becoming root-bound. To sidestep this, consider up-potting to larger blocks in a timely fashion, allowing for continued root growth without stress. Monitoring and managing the moisture levels in the soil blocks is also central to resolving most germination problems.
