Orchids are a kind of flower that have a reasonably long vase life when cut fresh. They may keep their waxy, fresh look for anything from several days to many weeks after being cut. Even after being out of water for a full evening, the vast majority of orchid blossoms will maintain their pristine appearance. However, the length of time that they will maintain their freshness is contingent on a number of things. You have some say in determining the outcomes of these elements, but not all of them.
Orchid Shelf Life
There is a wide range of preservation potential among fresh-cut orchid flowers. For instance, flowers from Cymbidium orchids (Cymbidium [Group]), which are hardy in plant hardiness zones 10 through 12 according to the United States Department of Agriculture, may remain fresh in a vase for up to a month. According to the Missouri Botanical Garden, dendrobiums, which belong to the genus Dendrobium, are hardy in USDA zones 9 to 12 and produce blooms that remain for a long time, making them an excellent choice for use as cut flowers.
On the other hand, the lifespan of Oncidium (Oncidium Group) species, which are hardy in USDA zones 9 through 12, is often little more than a week. When flowers are used separately in corsages and are kept out of water, they often won’t survive more than a day. This is especially true if the corsage is kept in direct sunlight.
Flower Ethylene Sensitivity
Ethylene is a plant hormone that regulates fruiting and death in plants. Orchids such as Dendrobium and Oncidium, as well as the common Phalaenopsis orchids (Phalaenopsi s [Group]), which are hardy in USDA zones 10 through 12, are extremely sensitive to ethylene. Ethylene is a hormone that is produced by plants. It is important to avoid disrupting the pollen or removing the pollen caps since the orchid will get a message that its blooms are no longer required after their flowers are pollinated, and this causes the blooms to begin to fade. According to Cornell University, ethylene might be present in your home in the form of ripening fruit, which releases the chemical into the air. Keep orchids in vases away from the fruit bowl if you want them to live for a longer period of time in the vase. Orchids that are vulnerable to the effects of ethylene only live for three days after being exposed to it.
When purchasing fresh-cut orchids, it is ideal to do it just as the flowers are opening rather than after they have completely bloomed. This will ensure that the blooms remain in the greatest condition possible for as long as possible. Be careful to obtain them while the buds are still closed, however, since after the spike is removed, flowers often cease blooming beyond that point on.
What to Buy
Instead, either selecting sprays of orchids on their own or when picking bouquets that include them, seek for branches that already have two flower buds open. This is true whether you are selecting sprays of orchids on their own or bouquets that contain them. You might also ask the florist whether the orchid blooms have been pulse-treated, which is a process that can increase the shelf life of the product and in certain circumstances prevent it from becoming sensitive to ethylene.
If you grow orchids outside during the growth season, you may want to bring some of the blooms inside to brighten your home. You can do this by cutting some of the flowers and bringing them in. According to research conducted by the University of Massachusetts Extension, the best time to cut orchids is in the morning, after the dew that was on the plant has evaporated.
Cut Your Own
Maintain a cool temperature for the blooms, and recut the stems by running them under cold water. After that, put the trimmed orchids in a vase filled with water for display purposes.
It is not a cause for alarm if the flowers you purchase have been kept in cold storage since the majority of orchids, once cut, can withstand temperatures hovering just around freezing without suffering any harm. When you bring freshly cut flower sprays inside the house, you may put them in a vase and leave them at room temperature.
Cold Storage for Orchids
The majority of tropical orchid species are transported by florists at temperatures ranging from 54 to 64 degrees Fahrenheit. This is because lower temperatures allow them to maintain their beauty for a little bit longer. Keeping them at a colder temperature will perhaps let them survive a little bit longer.
However, they may last a little longer in cooler conditions, and florists transport most tropical orchid species at temperatures ranging from 54 to 64 degrees Fahrenheit. Keeping them cooler may make them last a bit longer.
