Growing

Growing cassava is most successful when you focus on establishing a woody, drought-tolerant shrub in well-draining soil. If you are planting in a new area of forest or cleared land, you may not need much preparation, but if you are rotating after another crop, ensure the soil is plowed several times to remove competing grasses. This plant thrives in acidic conditions, so aim for a soil pH between 4.5 and 6.0. Because the tubers can spread deeply and widely, avoid using heavy machinery near the plant during harvest, as any bruising or damage to the roots can cause oxidation, which darkens the flesh and reduces the quality of your starch.

When the roots are ready, lift them carefully to prevent injury. It is vital to remember that the leaves, seeds, and raw roots are toxic; they must be prepared correctly through cooking to ensure they are safe for consumption. Once harvested, keep the roots unwashed to help them last longer. For long-term use, you can dry the roots to create a fine powder for flour or starch. If you are growing in a container, ensure the drainage is excellent, as the plant does not tolerate waterlogged soil.
