Why is soil so important to the gardener? Because it limits the variety of plants that can be grown there. The health of any plant begins in the soil. As a matter of fact, poor soils are one of the most common causes for plant failure. All plants have evolved to perform well in certain types of soil. Cactus, for instance, prefer a soil that drains well. Whereas, aquatic plants prefer a soil that stays moist. Knowing your plants soil requirements will make you a successful gardener.
Silt particles are smaller than sand but larger than clay. It still feels gritty and is powdery when dry and slippery when wet. It is commonly found in flood plains.
