I. Roses
Text size: 
7.1
There are numerous cultivars of roses available in today’s market place. Due to the similarity of the bushes, special care must be taken in labelling. All bundles must be labelled and securely tied.
7.2
Long storage periods are frequently required. Special care must be taken to ensure that these plants are kept free of disease, damaged roots or branches. A well developed fibrous root system is essential.
7.3
Roses are produced by either budding the cultivars onto a rootstock or by rooting cuttings. Budding plants must have the understock identified.
7.4
If wax is applied to prevent desiccation during storage, clear wax or light coloured wax must be used.
7.5
Roses are to be graded as numbers 1, 1-1/2 and 2, according to the type, and the number and length of strong canes. All canes must be sturdy and in good condition.
