When raising aquatic plants in outdoor ponds, it is important to consider the amount of light available, the depth of the pond, the kind of soil, and various other factors. Since most aquatic plants obtain nourishment from the soil, it is necessary to have a soil rich in organic matter. In most natural ponds the accumulation of humus at the bottom is excellent for plant growth. In some ponds, however, the bottom consists largely of sand or gravel that must be covered with a thick layer of rich soil. If the pond is very large, it is often easier to root the plants in earth-filled boxes or pots than to place a thick layer of soil over the entire bottom of the pond. Most aquatic plants require large amounts of light and should not be grown in shaded areas. In some regions, it is also important to protect the plants from strong winds by growing shrubbery or other windbreaks near the edge of the pond. The depth of the water should be determined by the size of the plants. In many cases,...

Critics have wondered whether he will ever find the one great, career-defining role that eludes him. Pitt has nevertheless made his mark as an actor, especially in films that have struck a cultural nerve, such as Se7en (1995) and Fight Club (1999). William Bradley Pitt was born in 1963 in Shawnee, Oklahoma. He grew up in Springfield, Missouri. His parents, Bill and Jane Pitt, were devout Southern Baptists.
