Herb farming and spice crops let African growers earn good value from small plots, as long as they master planting, harvest and post-harvest handling. The guides in this category explain ginger farming from seed rhizome to harvest, garlic farming in cooler highland zones, and aloe vera and other aromatic crops, with practical advice on soils, irrigation, fertilization, drying and storage.

Plant healthy seed rhizome pieces with at least one bud in loose, well-drained, fertile soil, ideally on raised beds or ridges. Plant at the start of the rains or with irrigation, and mulch to keep the soil moist and cool. Feed with compost and balanced fertilizer, control weeds, and avoid waterlogging, which causes rot. Harvest when the leaves yellow and dry, usually after eight to ten months.
Garlic usually takes around four to six months from planting to harvest, depending on the variety and the climate. It grows best in cool, dry conditions, which is why highland zones suit it better than hot lowlands in tropical Africa. Harvest when most of the leaves turn yellow and dry, then cure the bulbs in a shaded, ventilated place before storage or sale.
Aloe vera can be profitable when a grower has a secured buyer, such as a cosmetic, beverage or herbal products processor. The plant tolerates drought and poor soils and needs few inputs, but leaves have low value if you sell them without a market or processing. Before planting at scale, confirm the species buyers want, their quality standards and the volumes they will take.
