The most common type of orchid to be cultivated at home is Phalaenopsis orchids, sometimes known as moth orchids. With their long-lasting, lovely blossoms, it’s easy to see why they’re so popular. However, knowing how to fertilize phalaenopsis orchids is essential for keeping them healthy and ensuring that they bloom again and again.
How to care for phalaenopsis orchids and how to fertilize them. Fertilize your phalaenopsis orchid once every 1 to 2 weeks during the growing season, and once every 3 to 4 weeks during the winter and when it is blooming. Use no more than half the recommended strength of an orchid-specific preparation.
Fertilizing your phalaenopsis orchid correctly can be difficult, so the rest of this post will go over all you need to know to make sure you get it right and keep your orchids healthy and happy.
Do you feed orchids when they are in bloom?
Orchid blooms’ rich hues can instantly brighten any environment, which begs the question: who wants to enjoy an orchid for only one season?
Though caring for your Phalaenopsis orchid is straightforward, adding another simple step to your routinefertilizingcan help give it an extra push, allowing it to continue to provide you with gorgeous blooms for years to come.
Orchids, like humans, require rest. And it is during this resting phase that your orchid receives the nutrition it requires to produce vivid blossoms for you. Consider the resting period to be your nightly slumber (though an orchid’s hibernation is more related to hibernation), and the fertilization process to be similar to taking a vitamin it’s not necessary for your health, but it can help if you need it.
Fertilizing your orchid isn’t as difficult as watering it. It’s even simple to set up a fertilization program to give your blooms a nutritional boost. Here are some guidelines for determining when, why, and how to fertilize orchids.
Fertilizing: The When
Fertilize your orchid once the last bloom has faded. Fertilize your orchid at least once a month and no more than once every other week when it is resting. On the weeks that you fertilize, you don’t need to water. While your orchid is in bloom, you can fertilize it, although it isn’t necessary. This procedure should be done during the resting phase of your orchid’s life to provide extra nutrients for reblooming.
Fertilizing: The Why
Orchids thrive in a tropical atmosphere, which, let’s face it, isn’t present in most households. Fertilizing your orchid not only gives it a boost in energy for reblooming, but it also feeds it with nutrients it wouldn’t get in its natural habitat. Including fertilization in your care routine also aids in the replenishment of nutrients in your potting soil.
Fertilizing: The How
If you can’t find an orchid-specific fertilizer, use an all-purpose flower fertilizer with nitrogen, phosphorous, and potassium. You’ll want to dilute the fertilizer by half by mixing it with water. Then use a watering can with a narrow spout to apply it.
Fertilizing your orchid can be easily incorporated into your regular watering routine to ensure that your blooms remain healthy and colorful. Download our free orchid fertilization guide for more detailed instructions on fertilization, including how to choose the proper fertilizer and more.
Do Phalaenopsis orchids need fertilizer?
After the blooms have faded, experts recommend fertilizing Phalaenopsis orchids every other week or at least once a month. Use a dilute solution of a balanced plant fertilizer to feed your orchid.
When should you fertilize orchids?
Feed cymbidiums as soon as their flowering time is through (or, if yours haven’t flowered yet, when those in your neighborhood have). Dynamic Lifter pellets are great for spring fertilizing a modest dusting of pellets every six weeks should suffice. Switch to a flower-promoting liquid, such as Yates Thrive Orchid Food, after Christmas. Because they don’t last as long, they should only be used once every two weeks.
How do you fertilize Phalaenopsis orchids?
Fertilize with Searles Flourish Orchid Booster for the best results. Apply to foliage and soil every 7 to 14 days. Apply SeaMax Fish & Kelp every 2 to 4 weeks to boost plant resilience to pest and disease assault. Phalaenopsis thrive in humid environments, with humidity levels of 55-75 percent being optimum.
Should I fertilize orchids with buds?
When orchids are actively producing leaves and roots, they require very little fertilizer. Their active growth stops as they produce flowers, reducing the quantity of fertilizer they require even more. Fertilizers should be used at a quarter strength, or 1/4 teaspoon per gallon of water. Follow the package instructions and combine at the appropriate rate if you’re using an orchid-specific flowering fertilizer. During the blooming stage, fertilize budding orchids once every three to four weeks. After the last bloom has faded, return to your regular fertilizing program.
Do Phalaenopsis orchids rebloom?
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:
How do you stimulate the roots of a Phalaenopsis orchid?
You simply need to supply two conditions for an orchid to grow roots: a warm temperature and enough moisture (but not too much) at the stem’s base. A seaweed extract high in plant hormones can also be utilized to stimulate root growth.
Can you use Miracle Gro on orchids?
Apply 1/4 teaspoon Miracle-Gro Water Soluble Orchid Food per gallon of water to orchids and other indoor acid-loving plants every 2 weeks during active growth phases and every 4 weeks during rest periods.
1 tablespoon per gallon of water can also be used on outdoor plants: mix 1 tablespoon with 1 gallon of water and apply to soil. When compared to unfed plants, apply every two weeks to help develop bigger, more beautiful plants.
How many leaves can Phalaenopsis have?
Growing healthy plants is the first step in blooming orchids. A healthy orchid with a lot of leaves and roots will blossom quickly. It will not blossom if the roots are decaying. It will not blossom if it does not produce huge new leaves. Or, if it blooms at all, it does so in a desperate attempt to survive before dying.
Three to five leaves are present on a healthy phalaenopsis orchid. They rarely have more than 5 in the house, and 4 is more frequent. When it reaches this mature size, new leaves will emerge, while an old leaf will fall off.
A mature leaf’s size is determined by the cultivar. The leaves of orchids with larger flowers are usually larger. The leaves of orchids with smaller flowers are smaller. All of this is determined by genetics, and there is only so much you can do to increase the size of your leaves.
Despite this constraint, you can still control the size of the leaves. Good culture, particularly more light, will result in larger leaves to the extent that rage generics permits.
Should I fertilize my orchid after repotting?
After repotting your orchid, spray its leaves lightly for two weeks. Fertilize your orchid the second week after repotting, using rooting solution instead of fertilizer. During the weeks that your Phalaenopsis is fertilized, do not water it. For the first month, fertilize your orchid every other week.
