Soil blocks are a game-changer for gardeners seeking an efficient and sustainable approach to seed starting. By eliminating the need for traditional pots, soil blocks minimize transplant shock, fostering healthier root development and robust plant growth. The enhanced air circulation around the roots prevents issues like root rot and encourages resilient plants. This method proves cost-effective, reducing the reliance on plastic pots and minimizing waste. With environmental benefits in mind, soil blocks are biodegradable and can be directly planted into the ground, contributing to a greener gardening practice. Additionally, their space-efficient nature, easy DIY preparation, and adaptability to various crops make soil blocking a versatile and time-saving choice for both novice and experienced gardeners.

Using soil blockers to grow plants is an ancient Mexican technique which has been adapted for the modern home and commercial gardener. A soil block is a compressed unit of soil blocking mix which holds together negating the need for planting in a pot. As seeds germinate and grow, their roots eventually reach the edge of the block, where they become exposed and 'air pruned'. This means they stop growing from the tip and develop a branched root system within the ladbrooke soil block. In a pot these roots would continue to grow and if not potted, can wrap around the inside of the existing pot causing the plant to become "root bound'. A 'root bound' plant can suffer poor growth after it has been transplanted.
