Some people enjoy the natural look of a clay pot, especially when the appearance of the plant rather than its furnishing value in the room or garden patio is all-important. The overall effect of most Specimen Plants is, however, improved by being placed in a pot holder. These pot holders come in many materials, shapes and prices – you can buy ones made of wire, plastic, pottery, wood, glass fibre, cane or metal. Apart from these shop-bought types there are also many ordinary household objects which can be used – popular examples include copper bowls and kettles. The one rule for any pot holder is that either the lower part or all of it must be waterproof.
