Phalaenopsis (moth orchids) are among the most straightforward orchids to grow. Blooms can last for several months and can be rebloomed with little care. Some people, at least, can. I’ve had no luck getting another bloom, as evidenced by the shelf of non-blooming phalaenopsis. To be honest, I’m a little embarrassed. What can I do to get my orchids to blossom once more?
In order to maximize my chances of success, I spoke with Anita Nadeau, our orchid expert at Gardener’s Supply. She assists customers in the conservatory at our garden center in Williston, Vermont. Here are her suggestions for reblooming phalaenopsis:
What do you do with an orchid after the blooms fall off?
You have three options when the orchid’s blooms have dropped: leave the flower spike (or stem) intact, trim it down to a node, or remove it completely. By trimming the flower spike off at the plant’s base, you can completely remove it. If the existing stem begins to turn brown or yellow, this is the path to take.
How long does it take for a phalaenopsis orchid to rebloom?
A constantly damp potting mixture could be the result of overwatering, or it could be the result of the potting material breaking down over time and becoming so compacted that it no longer drains efficiently. It will starve your plant roots of oxygen and nutrition, as well as harboring rot and disease, if it has began to disintegrate. You could also wind up with a harmful buildup of mineral salts if you don’t drain the potting material out between fertilization.
If you see that the potting mixture has degenerated to the point where the roots are being damaged, you should repot your orchid in fresh growing material as soon as possible to save the plant. After repotting, your phalaenopsis orchid will take at least six months to regain the strength to blossom.
Orchid Spike Care
- Cut the spike (stem) 1 inch above the first node below the lowest flower bloom if the spike is still green (as shown in the image above).
- Trim the flower spike at the plant’s base if it’s starting to turn brown. On brown spikes, Phalaenopsis orchids will not blossom.
- Cut one spike 1 inch above the first node below the lowest flower bloom and the other spike at the base of the plant if your orchid has a double spike.
Your orchid is dormant, but not dead, at this time. This is how it will look for the next six to nine months, until fresh flowers arise.
Orchid Dormancy Care
Even when your orchid is dormant, it requires water and attention. To assist reblooming begin, follow these easy procedures.
- Once a week, water your orchid with three ice cubes. Use 2 cubes for a petite orchid and 1 cube for a small orchid. If you’re using a planter with multiple plants, make sure each one has its own set of cubes.
- Fertilize your orchid once or twice a month using a half-strength balanced houseplant fertilizer. During the weeks when your orchid is fertilized, avoid watering it with ice.
- At night, move your orchid to a cooler location. The arrival of fresh flower spikes is aided by cooler nighttime temperatures (55 to 65 degrees Fahrenheit). You can reset your orchid to its normal setting after a new spike appears.
How many years do Phalaenopsis orchids live?
Moth orchids (phalaenopsis) are one of the most popular indoor plants, and for good reason. They have beautiful flowers, as you can see in the photo, that receive their name from their moth-like look. When you combine that with the fact that they are really easy to care for, you have the perfect houseplant.
What is the average lifespan of phalaenopsis orchids? People frequently discard them once they have completed their flowering cycle due to their popularity and low cost. This normally lasts 2 to 3 months. However, some have been said to have lived for almost a century. So, with proper care and attention, you should be able to retain your orchid for several decades.
Because many individuals discard their orchids after the first bloom, they are often unaware that the plant is actually resting in preparation for the next bloom.
This is where it will store the energy needed to create such lovely or adorable blossoms as the monkey face orchid. You may expect a phalaenopsis orchid to bloom anywhere from once to three times per year. If you’re lucky and take excellent care of it, the latter.
A careful grower will be required to keep this plant alive for several decades. However, there are a few simple steps you can take to help it last longer.
How long will it take my orchid to rebloom?
Reblooming Phalaenopsis orchids can take a month, two months, or even several months. Many additional orchid kinds bloom on a yearly basis.
Will an orchid grow a new stem?
Orchids, thankfully, can sprout new stems. Stem cuttings can be used to propagate new Phalaenopsis or Vanda orchids. You can also anticipate a flower spike to regrow after its blossoms have died if you cut it down.
Do you still water orchids after flowering?
Orchids require a time of rest after they have finished flowering before they may resume flower production. Pseudobulbs, which are fleshy stems that store water and nutrients, are found on several orchids, including Cattleya and Oncidium. Reduce watering during their post-flowering rest time. These cultivars may rot and perish if they are overwatered. Because phalaenopsis and Vanda orchids lack pseudobulbs, you must water them thoroughly when the potting mix is nearly dry to prevent them from drying out altogether. Reduce fertilization until new leaves appear on all kinds, then fertilize at maximum intensity with a water-soluble orchid fertilizer mixed according to label guidelines.
Do orchids grow back every year?
Understanding all four stages of orchid growth (leaf growth, flowering, root growth, and dormancy) can assist you properly care for the plant and help it grow back and bloom numerous times during the season.
After the flowers have fallen off, orchids grow back and rebloom. All you have to do is take proper care of them and they will blossom year after year. You’ll get the hang of it with a little practice here and there.
Will an orchid Rebloom on same stem?
Let’s talk about the Phalaenopsis orchid, often known as the moth orchid, which you probably bought at the grocery shop. The only orchid that reblooms on the same stem is this one. All other orchids will bloom again, although not on the same stem as the first. All other orchids can have their bloom stalks cut at the base.
There’s one more thing I want to emphasize: only clip the flower stalks, not the pseudobulbs. Although Phalaneopsis, Paphiopedilums, and Vanda orchids lack pseudobulbs, the majority of orchids do. If you’re growing Dendrobiums or Cattleyas, for example, don’t cut the flower stalk off at the base of the plant; instead, trim it. If you observe a bulge in the stem, it’s a pseudobulb, which you shouldn’t cut. If a stalk has leaves sprouting off it, don’t cut it.
Why is my Phalaenopsis orchid dying?
For a variety of causes, they can wilt. It could be due to a lack of water, fertilizer, or light, among other things. Plants that are overwatered will wilt and die. Orchids can wilt and perish if they are grown in the improper medium.
