Adjective: aaa

  Of a potted-grown plant when the root growth has filled the pot and the plant has grown too large for its container resulting in matting or tangling of the roots  
     
Pot-bound is the condition of a plant growing in a pot in wich the root growth has filled the pot to the extent of eliminating all air spaces resulting in poor leaf and stem development.
The impacted and encircling root system develops when a plant has been grown in a container that is too small or when a plant has remained too long in it's pot, or container, and it's roots have become very entangled and all of the nutrients in the soil have been used up.
If the plant is not soon repotted in to a larger container and the roots carefully separated, it will have little ability to absorb food and it's growth will slow drastically, or completely stop. A pot bound plant will also have a reduced ability to resist pests and diseases.

Holdfast roots  [ Botany  ]

Dictionary of botanic terminology - index of names

 
     
  Some species of climbing plants develop holdfast roots which help to support the vines on trees, walls, and rocks. By forcing their way into minute pores and crevices, they hold the plant firmly in place.  
     
Climbing plants, like the poison ivy (Toxicodendron radicans), Boston ivy (Parthenocissus tricuspidata), and trumpet creeper (Campsis radicans),  develop holdfast roots which help to support the vines on trees, walls, and rocks. By forcing their way into minute pores and crevices, they hold the plant firmly in place. Usually the Holdfast roots die at the end of the first season, but in some species they are perennial. In the tropics some of the large climbing plants have hold-fast roots by which they attach themselves, and long, cord-like roots that extend downward through the air and may lengthen and branch for several years until they strike the soil and become absorbent roots.
