After the flowers drop from the orchid you have three choices: leave the flower spike (or stem) intact, cut it back to a node, or remove it entirely. Remove the flower spike entirely by clipping it off at the base of the plant. This is definitely the route to take if the existing stem starts to turn brown or yellow.
This dormancy stage is a resting period where the plant has time to replace nutrients that were dispensed during the blooming process. This dormancy stage usually lasts about six to nine months. After that, your orchid will have the energy to rebloom again.
They will bloom again, but in the meantime, you have a few options: You can let it be, while making sure to fertilize it monthly or sometimes even as often as every other week. Use a houseplant fertilizer or balanced fertilizer (example: 20-20-20) at half the recommended rate.
While each growing environment is unique, and watering habits vary from person to person, it is generally a good idea to water about once per 7-10 days, when the mix gets dry. Too much watering leads to root rot, crown rot and other over watering problems like fungus gnat infestations.
Trim 1 inch above that node, or bump, on the orchid spike. For unhealthy, brown spikes: Cut all the way back to the base of the plant. For double-spike orchids: Cut one spike at the base of the plant. Cut the other spike 1 inch above the node under the lowest flower bloom.
Do you trim orchid stems? You should trim the stem of a phalaenopsis orchid after blooming has finished. Trim your orchid just above the node on the stem directly below where the first flower bloomed. This will increase the chance of another cycle of blooming from the same flower spike.
To master watering orchids, it is essential to water from above with fresh, pure water. For orchids with water storage, pseudobulbs, water when the potting mix is approaching dry.
If you find that your orchid has bad roots, snip them off with a sterilized cutting tool and then repot it. On the other hand, if the part of the orchid that connects the leaves and the roots is mushy, it is time to toss the plant.
Your orchid has tightly tangled roots.
This is a surefire sign your orchid needs to be repotted. Give plants breathing room by placing it in a larger pot every year or two with fresh potting soil.
You may also want to mist the orchid with a spray bottle daily. Misting gives the orchid more humidity but does not create a soggy root environment. It is best to put your orchid where it will receive medium indirect sunlight.
The best place to water your plant is in the kitchen sink. Use lukewarm water (do not use salt softened or distilled water) and water your plant for about 15 seconds and be sure to thoroughly wet the media. Then allow the plant to drain for about 15 minutes. It may appear dry but it has had enough water.
Let's talk about the Phalaenopsis orchid or moth orchid, the one you likely got from the grocery store. This is the only orchid that will rebloom on the same stalk. All other orchids will bloom again, but not from the same stalk. All other orchids can be trimmed at the base of the flower stalk.
In homes with low humidity, air roots can turn yellow and shrivel. If this occurs, wait until your orchid stops blooming, and then use a sterile knife or scissors to cut away the shriveled roots.
In the wild, orchids are able to live about 20 years, depending on the type of orchid and the environment. Potted orchids do not have quite the same life span, but with proper care, it is not usual for orchids to live for between 10 to 15 years. There are some reports of orchids living for significantly longer.
Place the blades of the scissors around the stem of the dead flower, where it attaches to the flower spike. Cut swiftly to produce a sharp cut. Throw the severed bloom in the trash, so that it will not spread diseases to the plant or other nearby plants. Continue removing each faded flower along the flower spike.
So post-bloom orchid care is really just good care for the plant at any time. Provide light but not direct sunlight, consistent moisture, air circulation, and temperatures of 75 F. (23 C.) during the day and 65 F.
Orchid flower spikes are usually greener than roots and have a flatter, mitten-shaped tip. While growing, spikes remain green along their full length. Orchid spikes usually emerge from between the plant's leaves, not from the plant's center.
An orchid generally needs water once a week during the winter and twice a week when the weather turns warm and dry. An orchid shouldn't go longer than two to three weeks without water; it will start dying.
Soak for about 10 minutes to saturate. Allow the water to drain out completely; orchids like a good soak but don't tolerate sitting in water. Uneven watering will result in shallow or uneven root growth. After you have watered your orchid, feel the weight of the container; it will be heavy.
Any orchid can be grown in water with just a little patience. You're ready to wow your friends and family with an impressive-looking but easy to maintain setup! Keep an eye out for root rot, make sure your water is fresh, and add a touch of decorative flair. It'll spice up your house and keep your plant happy!
Caring for orchids
In most centrally heated homes the air is dry, so mist the foliage every two to three days using tepid water, but avoid spraying the flowers, as the petals can be marked by water. Overwatering is the most common way to kill orchids.
It is well known that orchids are shade loving plants and you shouldn't let them be exposed to too much sunlight. The harm to an orchid is huge when exposed directly under the fierce sunshine in hot summer.
