Large glass-dishes are also used for growing plants. The mouth of the dish is kept closed by putting a glass-cover over it. In a dish, trough or shallow bowl, the plants are grown without being covered by a glass as in a terrarium or bowl.
Small plant arrangements using suitable types of plants illustrating a particular landscape in a miniature form can be designed in a large dish or trough.
Cacti and succulents are excellent subjects for creating desert scenes by planting amidst small pieces of stones and pebbles.
It is advisable to plant cacti and succulents in separate dishes or bowls instead of putting them together.
Araucaria, Pine seedlings, Dwarf maiden –hair Fern, Selaginella and some other small plants can be effectively utilized in producing wood land scenes.
The plant compositions should be rhythmic and simple with proper harmony, in colour, texture and form of leaves, flowers and plants.
The plants grown in a dish should have similar requirements of water and light and preferably also have similar growth habit so that the fast growing plants may not smother the slow-growing plants.
Regular and proper watering and light are essential in maintaining the plants indoors in a healthy condition.
After two-three years, when the plants outgrow or lose their form, it may become necessary to undo the arrangement and create the composition again with small young plants.
