In environmental science, it has been known for ages that the type of soil you plant your seeds in affect its growth. But what is the best kind of soil to best grow the specific snapdragons flowers. We know that the nutrients in soil are the largest contributor to a plant's growth. The idea soil for snapdragon flowers is rich, well-draining soil, with a neutral to slightly acidic pH, amended with raised beds or loosened soil to improve drainage making soil vary in environment and adaptability. It is known that the ideal soil mixture is loamy soul, with 2-3 inches of compost in a well-draining high quality pot mix, but it is unknown which exact brand and typing of soil best grows snapdragon flowers height. In thesis, we experiment a technique in planting 2 seeds in each soil type, same environment, same amounts of added water, same amounts of soil and the same type of pots, allowing exact growth between all the seeds, an almost exact allowing a fair comparison between soil times, reducing experimental error. We describe a series of experiments with the six types of soil, and show that in varying cases, little to no height growth within the flowers occurred efficiently within high nutrient soils, and almost rapid height growth occurred within less nutrient, natural soils. We expect an increased use in artificial soils to become the only way to grow plants efficiently since artificial soils hold more macro and micronutrients which stimulate growth quicker than natural soil.
