Tips to Manage Vegetative URC Deliveries • Open the boxes immediately upon arrival. Select an area that is protected from direct sun to unpack and inspect the cuttings. • It is important to stick the most sensitive products first to avoid added propagation stress. Crops such as vegetative geranium, euphorbia, lantana, and heliotrope should be stuck as soon as possible to reduce leaf yellowing, leaf drop, and tip burn. • If cuttings must be held, store them in a cool environment with high (70%+) relative humidity. • In general, most vegetative annuals can be stored at 50 °F. • More specific storage temperatures by genera are required for long-term storage. For example, geranium cuttings can be stored at 36–50 °F, while impatiens require a 50 °F storage temperature. • Storage temperatures above 65–70 °F can result in increased respiration and cutting dehydration. • It is recommended that you do not store any cuttings for more than three days.
