Container grown plants should have been grown in the container for sufficient time for the root growth to have substantially penetrated the medium but not be root bound. The rooting must be well balanced in accordance with the container size. Plants are to be centered in the container, well rooted, firm and moist on delivery, with the growing medium coming within a suitable depth of the pot rim, taking into account the size of the container and the age since potting. The surface of the growing medium shall be free all weeds. Plants shall be supplied in rigid containers or polybags. If polybags are used, then this should be stated. Container grown plants are defined by ‘C’ followed by a number indicating the volume in litres, e.g. C5.
Forest conifers are also grown in Japanese Paper Pots (JPP’s).
These biodegradable containers are used for raising seedling forestry stock. |
