Hurray, the cassava farm is almost ready for harvest. Right now it is currently 7 months old. This means that harvest is in 3 months. Early-maturing cassava varieties are ready for harvesting at 7 months, but for it to reach maturity; it should be left for 10 months. At this stage, the leaves turn yellow and fall down and the roots are mature. It is advisable to harvest cassava once it is mature. If the tubers are left in the ground over long periods, they lose quality and become woody due to hydrolysis of starch to sugars.
