Cassava (Manihot esculenta), also known as manioc or tapioca, is a versatile tropical woody shrub with culinary uses extending from its leaves to its tuberous roots. In this guide tailored for hobbyist gardeners, we’ll delve into the intricacies of growing and utilizing this hardy plant, offering tips and interesting details to make your cassava cultivation a success.
Botanical Overview
- Botanical Name: Manihot esculenta
- Common Names: Cassava, manioc, tapioca
- Family: Euphorbiaceae
- Origin: Central and South America
Plant Description
Cassava is a robust shrub, reaching heights of 3-4 meters, with large, lobed leaves and enlarged tuberous roots. Its irregular branching pattern and hardiness make it adaptable to various soils, showcasing resilience in tropical conditions.
Uses
- Leaves for Consumption: Cassava leaves, when cooked, offer a source of protein, iron, and B vitamins. Boil them for at least 15 minutes to neutralize harmful glucosides. While cassava leaves are an option, other tropical greens like sweet potato leaves, pumpkin tips, kangkong, or Ceylon spinach might be preferred.
- Tuberous Roots: Harvest the roots when the leaves yellow and fall. These roots can be boiled, fried, baked, or processed into flour. Tapioca pearls, derived from refined cassava starch, are used in soups, puddings, and dumplings.
Planting Details
- Recommended Planting Time: All year in the tropics; warmer months in subtropical regions.
- Growing Details: Plant woody cuttings upright in the soil, with the sloping end facing up. Cut the tops of the cuttings at an angle to prevent water stagnation and reduce the risk of rot. Optimal cutting material comes from plants at least 10 months old, 2.5 to 4 cm thick, and about 20 – 30 cm long, with 3-6 buds per cutting. Bury the cuttings to half their length, ensuring several buds are beneath the soil. Cuttings root easily, establishing plants within two months. Space plants 80 to 140 cm apart.
Tips for Hobbyist Gardeners
- Ample Watering: Cassava appreciates sufficient water, particularly during dry spells. Regular watering contributes to robust plant growth and healthy root development.
- Harvest Timing: Harvest tuberous roots when the leaves start yellowing and falling. This indicates the peak of starch accumulation in the roots.
- Soil Considerations: Cassava is tolerant of a wide range of soils, but well-drained soil is essential. It’s adaptable to different pH levels and soil types.
- Cooking Safety: Exercise caution when consuming cassava leaves, ensuring they are thoroughly boiled to eliminate harmful compounds.
