A cultivated plant either which blossoms or has only leaves can be provided over a long time interval simultaneously with moisture and a nutrient material without watering. A root ball containing the nutrient material including the roots of the plant is surrounded by a moist material which simultaneously uniformly feeds it and supplies it with moisture. This moist material is advantageously formed from a mixture of swollen and then broken clay pieces and from a plurality of cellular or foamed plastic material pieces which is provided surrounding the root ball in a container for the plant advantageously in the ratio of about 2:1 or 3:1. In this way the plant with the usual earth or humus root ball can be provided with moisture uniformly over a long time interval without requiring that a particular container or plant be used.
In a planter for a cultivated plant, particularly a house plant for home and office, comprising substrate in the form of a moist material which supplies moisture and an earth or humus root ball which provides a nutrient material for said plant, said substrate being filled into a pot-shaped container, the improvement wherein said moist material surrounding said root ball comprises a mixture of clay bodies and broken lava pieces of a particle size of 4 to 8 mm and cellular or foamed plastic material pieces of a particle size of 4 to 6 mm, which surround directly said root ball and are mixed with each other such that the volumetric ratio of the sum of clay bodies and broken lava pieces to foamed plastic pieces is 3:1.
A house or office plant arrangement requiring infrequent watering, comprising:
