Entrepreneurial Botany studies how new businesses are built around plant resources, and the actual process of starting one — an entrepreneur has an idea and builds the organisation needed to sell a product or service based on it. This concept covers six concrete, small-scale ventures a Botany student can realistically start. Mushroom cultivation grows the protein-rich fruiting bodies of edible fungi (button and oyster types) on sterilised straw under controlled humidity and temperature. Single Cell Protein (SCP) production grows a protein-rich microorganism, illustrated here with the alga Spirulina, cultured in a simple aerated aquarium under sunlight. Seaweed liquid fertilizer is brewed by soaking rinsed seaweed in water for weeks, releasing dozens of plant nutrients once diluted and applied. Organic farming replaces chemical inputs with natural ones — biofertilizers, a home-made chilli-garlic pesticide, and a neem-based bio-pest repellent are all covered as practical preparations, alongside a soil-ball 'hanging garden' planting technique. Terrarium-making builds a sealed miniature garden in glass, layered with pebbles, charcoal, soil and small plants, sellable as a decorative or gift item. Bonsai, a Japanese art form, trains miniature trees in containers toward named silhouette styles (Formal Uprig …
