Flowers generally handled by florists are cut flowers, that is, flowers that are cut from the whole plant without roots, and whose life cycle is about to end. The basic principle of handling flowers is to maintain their life and prolong the storage period. It is recommended to start from the following aspects:
Moisture - The function of water is to transmit nutrients to various parts of the plant and make the stems firm. To make the flowers bloom, it is necessary to add appropriate water. For example, plants with hollow stems, such as delphinium and Zhu Dinglan, need to give more water. The petals have waxy surfaces such as anthurium and cymbidium, which require relatively little water due to the slow evaporation of water.
Nutrients - Nutrients are also the factors that make flowers bloom and sustain life. Flower preservatives (including nutrients and fungicides) can be used to prolong the shelf life of flowers.
Bacteria - Bacteria will affect the healthy growth of plants, and will also block the suction pipes in the flower stems. Therefore, the stem part of the flower immersed in water must be removed from all miscellaneous leaves. The water for growing flowers needs to be replaced every day, and at the same time, about 2 cm of the flower stems should be cut off.
Temperature - The most suitable temperature for storing flowers is close to the temperature of the place where they are grown. For example, flowers from temperate regions prefer cooler temperatures, such as roses, bellflowers, carnations, etc. But subtropical flowers love warmer temperatures, such as anthurium, orchid, etc.
In addition, high temperature makes flowers easy to evaporate water and accelerate aging, so it is not suitable to expose flowers to sunlight. Cooler temperatures can slow down the growth of flowers, thereby prolonging their storage period. In the flower shop, flowers from temperate zones can be stored in a wind cabinet (about 11-15 degrees Celsius) to keep fresh.
Humidity - Appropriate humidity slows down the volatilization of water in flowers. Generally, the humidity of the wind cabinet is about 80-90%, which can slow down the volatilization of water from flowers, and the leaves that are not fluffy can directly spray water on the leaves to moisturize.
Cutting method - use a diagonal cut to cut the flower feet to increase the water absorption area. For example, woody flowers can be cut off at the end of the skin or cut into a cross cut. If it is too thick, the end can be cracked to increase the water absorption surface.
Ethylene - Flowers will release a gas called ethylene during the ripening stage. This gas can stimulate plant flowering, fruit ripening, leaf fall, and easily spread to surrounding objects. Therefore, the storage of flowers requires ventilation and should not be too crowded. Avoid storing mature flowers with immature flowers.
