9cm marginal plants require potting into a mesh basket.

1ltr marginal plants do not require repotting. However, plants over 60cm height growth will benefit from repotting into a larger mesh basket or should be planted in gravel to prevent them from falling over.

3ltr and 5ltr plants do not require repotting; there is no need to remove the mesh basket.
