Cassava

About

Cassava is a shrubby perennial that can reach heights of 6 to 8 feet (1.8 to 2.4 meters), characterized by smooth, erect stems and large, palmate leaves with dark green coloration and reddish veins. The plant produces starchy, tuberous roots that are a staple food in many tropical regions. While primarily grown for its edible roots, cassava also offers ornamental value due to its lush foliage. 🌞💧 **Sun and Water Requirements:** - **Sun:** Prefers full sun but can tolerate partial shade. - **Water:** Requires well-drained soil and is drought-tolerant once established; however, consistent moisture promotes optimal growth. ✂️🫘 **Methods to Propagate:** - **Stem Cuttings:** Plant 2- to 3-inch (5- to 7.5-centimeter) sections of mature stems directly into the soil during the warm season. 🧑‍🌾👩‍🌾 **When to Harvest:** - **Roots:** Typically harvested 8 to 12 months after planting, when they reach a desirable size. - **Leaves:** Can be harvested periodically for use as a leafy green, ensuring some foliage remains for plant health.

Permaculture Functions

• **Edible: ** The starchy roots are a major carbohydrate source, consumed boiled, fried, or processed into products like tapioca. The leaves, rich in protein, are used as leafy vegetables in various cuisines.
• **Animal Fodder: ** Both roots and leaves serve as feed for livestock, providing essential nutrients.
• **Erosion Control**: With its extensive root system, cassava helps in stabilizing soil and preventing erosion, especially in tropical regions.
• **Biofuel: ** Cassava's high starch content makes it a viable source for bioethanol production, contributing to renewable energy efforts.

Practitioner Notes

• Bitter types need specific processing to drop cyanogenic compounds—sweet types are milder but not a license to skip homework.
• Propagate from mature wood cuttings with obvious leaf scars—pencil-thick stakes root faster than toothpick twigs.
• Mite damage shows bronze stipple on upper leaves—release predatory mites early at first stipple, not at bronze paper stage.
• Harvest roots after leaves yellow or before heavy frost—frozen tubers turn to mush in storage.
