Horticulture Guidelines

• Exhibitors are allowed three entries in each class, provided each specimen is a different cultivar/variety/species.
• All entries must be grown by the exhibitor.
• Specimens must be shown with their own attached foliage only.
• Where three specimens of the same cultivar are asked for, the specimens should be uniform, free of disease or insect damage and at a similar stage of maturity.
• Where a definite number of specimens is specified that number must be adhered to.
• Buds showing colour are considered blooms.
• When a height limit is specified for an annual or perennial, this refers to the growing height of the plant, not the cut length of the specimen.
• Houseplants must have been in the possession of the exhibitor for at least three months prior to the show and must not be shown more than once in any six-month period.
• Potted plants may have only one cultivar per pot unless stated otherwise.
• Plants should be clean and well-groomed. Insect-infested or diseased entries will be removed from the show.
