In many respects, small containers are more difficult to place. Several small containers scattered about do not necessarily make a bold impact and can look fussy. Furthermore, a group of small containers can also be more difficult to maintain. However, they do come into their own when placed around the edges of larger containers to soften their outlines.
It was once thought that dangerous radioactive wastes could be dumped in sealed containers in the ocean depths. If the containers were to corrode, the radioactive substances would be released into the water containers from and gradually circulate around the globe, poisoning marine life.
IT IS ESSENTIAL that containers have adequate drainage otherwise the planting medium will get water containers fromlogged and the plant roots rot. Make sure the containers have at least one large central drainage hole if not more, and place a layer of crocks (broken pieces of clay flowerpot) on the bottom of the container before filling it with compost Containers should also be raised from the ground on bricks or flat stones so any exces water containers from can drain out.
A layer of well-washed pea gravel can b( used instead of crocks for more permanent displays, such as those involving shrubs or small trees.
