Pothos N Joy is a tropical houseplant with gorgeous white and green variegated foliage. And as you’ve probably guessed, it’s fun and easy to care for. After all, how often do you come across a plant that literally has the word ‘enjoy’ in its name?
Compared to other pothos varieties, the NJoy has one unusual trait: it grows very, very slowly. As a result, this plant can put your patience to the test, as it can take up to a year to reach a considerable size.
But if you’re a patient and slightly forgetful gardener, this plant will be perfect for you. You don’t need to worry about monitoring temperature and humidity, pruning, or wondering if your pothos will die if you forget to water it for a few days.
Of all the variegated plants you’ll come across, the NJoy is one of the most forgiving.
Read on to discover more about this plant’s origin and history, how to meet its care requirements, and most importantly, how to help it grow faster.
What Is Pothos NJoy?
Pothos NJoy is a patented Epipremnum cultivar with variegated white and green leaves and a compact, bushy shape. The spelling of the name can vary depending on the seller, and you may find it listed as N’Joy, N-Joy, or N Joy.
This variety was discovered by plant breeder Ashish Arvind Hansoti in 2002 in a commercial greenhouse in Mumbai, India. The plant was a naturally-occurring mutation of the Marble Queen pothos. It had shorter leaf internodes and, unlike the parent plant, it had distinct portions of white variegation rather than marbling.
After its discovery, it was propagated through cuttings for 25 generations to ensure that the new leaf patterns and shape were stable. The plant was then patented in 2009 under the name NJOY.
How To Identify Pothos NJoy
The main feature of Pothos NJoy is its variegated foliage. The leaves can be white or pale cream, with dark green and bluish or silvery green sections. You may also notice a few light green speckles, although they are rare.
The NJoy has a compact growth habit. Unlike most pothos varieties, it has shorter gaps between the leaf nodes. The leaves are also smaller, with a slightly triangular, sometimes oval shape, and lightly ruffled texture.
The scientific name for Pothos NJoy is Epipremnum pinnatum var. NJOY. According to the patent, anyway.
However, the patent mentions that this is a variety of the Marble Queen pothos, which is an Epipremnum aureum or Devil’s Ivy cultivar. Therefore, technically speaking, the botanical name for this plant should be Epipremnum aureum var. NJOY.
N’Joy Pothos Benefits: Purify the Air? (What Science Says)
You probably read or heard that the Pothos NJoy helps purify the air in your home by removing toxic chemicals such as benzene, formaldehyde, and ammonia. But is this actually true?
The NASA Clean Air Study took place in 1989. The N’Joy was only patented in 2009, so it’s impossible that scientists would use it in their study. Scientists did study the Golden Pothos (or Scindapsus aureus, as it was listed in their final report). However, there are several morphological differences between the NJoy and Golden Pothos. And just because they’re both pothos plants doesn’t mean they work the same way.
Another thing to note is that the N’Joy is a variegated plant with large white leaf sections. Those white areas don’t contain chlorophyll, so the plant can’t use them for photosynthesis. So the N’Joy absorbs carbon dioxide and creates oxygen at a lower rate than other varieties, such as the Golden Pothos.
Even though the Pothos NJoy is not an excellent plant for purifying the air, it does have its benefits. It tolerates low humidity, can survive in high and low temperatures, and has a slow growth rate so that it won’t take up a lot of space. Plus, it’s a gorgeous plant with high ornamental value.
Pothos N Joy Care Guide
The most important thing to remember about the Pothos NJoy is that it’s a slow-growing variegated plant. This will impact all aspects of its care requirements, from light and soil to pruning and repotting.
But once you get the hang of it, you’ll discover that this plant is straightforward to grow and won’t mind a bit of neglect.
The NJoy pothos has a slow growth rate. It takes a long time to put out new leaves and stems, and the new leaves take a long time to unfurl. The space between each leaf node is also shorter than in other pothos varieties, which means that the vines will take months to trail or hang over the pot’s edge.
How fast does NJoy pothos grow? On average, you can expect it to grow between 6 to 12 inches in length each year.
Funnily enough, the patent for this pothos mentions it has a rapid growth rate. But that growth rate was observed in the conditions the plant was developed in. The average home is cooler, drier, and darker than a greenhouse in Mumbai, so naturally, the plant will grow slower.
Pothos NJoy needs bright indirect light to maintain its variegation. If you keep it in low light, the leaves will gradually revert to green and become smaller. On the other hand, too much sun and direct light can scorch the foliage and result in dried, brown spots on the white leaf sections.
The NJoy pothos was developed in a polyplastic greenhouse in India. This type of greenhouse was also covered with a layer of shade cloth, which filtered natural light by 50%.
To match these light requirements indoors, your best choice is to keep it in an east or west-facing room, at least 3 feet away from the window. You can also use grow lights if your home doesn’t have enough natural sunlight.
The NJoy will also grow well under fluorescent lights, which makes it a great plant to keep in an office.
The ideal soil mix for the Pothos NJoy should be aerated, well-draining, and moisture-retentive. You can get great results by combining equal parts peat-based potting mix and perlite or pumice.
Remember that all overwatering problems start with the soil, not how much water you give your plants. If the soil has poor drainage, it can become waterlogged. This promotes fungal diseases in the root system that will lead to root rot.
Water your Pothos NJoy when the top 2 inches (5 cm) of the soil feel dry to the touch. Always test the soil with your finger before watering, and if it still feels damp, wait until it dries up a bit more. This variety will respond better to underwatering rather than overwatering.
The NJoy is more susceptible to root rot than other pothos cultivars. This is because it has a slower growth rate so it won’t need as much water as a Golden or Marble Queen. However, if the soil stays wet, the roots will start to rot, and the white portions of the leaves will develop soft, brown, or black spots.
Pothos NJoy grows best in a temperature range of 70°F and 86°F (21°C to 30°C). But for a tropical plant, it has a remarkable tolerance to heat and cold. The patent documentation states that it can live in temperatures as low as 43°F (6°C) and as high as 104°F (40°C) without suffering any damage.
You can move this plant outdoors from early spring until late fall. The increase in natural light will help it grow faster, but make sure you don’t put it in direct sun. When temperatures drop to 50°F (10°C) during the night, it’s best to bring it back inside the house.
The Pothos NJoy does not need lots of air moisture to grow. This makes it a great choice if you need a variegated plant for a home with low humidity.
But if you can increase the humidity to around 50% or 60%, your plant will thank you. You’ll start seeing faster growth and larger leaves. Simply putting the pot on top of a pebble-tray half-filled with water will help create a more humid environment.
Avoid misting this plant. Unless you do it several times a day, misting your NJoy won’t do anything to increase the humidity. It also increases the risk of bacterial leaf diseases, especially if your home lacks good ventilation.
The Pothos NJoy is a light feeder. You can get away with feeding it once a month from spring until early fall. A balanced fertilizer with a 10-10-10 or 5-5-5 nutrient ratio will help the plant grow faster and help it stay healthy.
Avoid overfeeding your pothos as tempting as it is, especially if you’re keeping it in low-light conditions. Too much fertilizer will burn the roots, cause leaf discoloration, and even make your pothos leggy. It will actually weaken the plant rather than make it grow faster.
Pothos NJoy needs minimal pruning. You can remove the older, yellowing leaves or trim the vines to maintain the plant’s length and shape. Pruning will also encourage the stems to branch out, making your pothos bushier.
Always use a sharp, sterilized blade for the job to prevent the spread of potential pests and diseases.
Repotting Pothos NJoy
Your Pothos NJoy needs repotting once every 2 to 3 years. The most common signs that your plant needs a larger pot are roots coming out of the drainage holes, reduced growth rate and yellowing leaves, and the fact that your plant needs more water than usual.
Even if your pothos hasn’t outgrown its container, it’s worth repotting it at least once every three years. In time, the plant will use up the nutrients in the soil, and the potting mix will lose its ability to retain moisture. Plus, a change of soil also prevents the buildup of fertilizer salts and pathogens.
When the time comes to repot your pothos, simply transplant it to a container that’s one size larger or 2 inches (5 cm) wider than the old one. Always make sure to use a pot with drainage holes, and avoid reusing the old potting soil.
Pothos N Joy Propagation Guide
You can propagate Pothos NJoy using stem cuttings. However, the cuttings take a long time to grow, so be prepared to wait up to 40 days before seeing any roots.
Here are a few tips for faster propagation:
- Try using single-node cuttings, or stem sections with a maximum of two leaves. If the cuttings are longer than 6 inches (15 cm), they won’t spend enough energy on root development.
- Propagate your NJoy cuttings in water or a plastic box filled with moist sphagnum moss. Soil propagation takes longer, and the cuttings are more likely to develop stem rot in the process.
- Keep the cuttings in a room where the temperature is at least 77°F (25°C).
- Apply a rooting hormone to help the cuttings grow roots faster.
- Provide plenty of natural light, but avoid direct sunlight exposure.
Common Pests & Problems
Pothos NJoy is resistant to most pests. But if the plant is stressed, it can become susceptible to spider mites, mealybugs, and thrips. Therefore, check the leaves at least once a week, especially their undersides, and take action as soon as you notice signs of pest infestations.
The most efficient treatment for spider mites and mealybugs is a 70% isopropyl alcohol solution. Mix 1 part alcohol with four parts water, and use it to spray the leaves once every 5 to 7 days. Repeat the treatment for at least a month or until all pests are gone.
If your pothos has thrips, isolate the plant and trim the infested leaves immediately. Unfortunately, homemade solutions aren’t efficient when dealing with this pest, so your best choice is to use a systemic pesticide.
Yellowing leaves are a common symptom of overwatering. But, leaves turning yellow can also indicate that your plant needs more nutrients or is suffering from pests.
The leaves of your Pothos NJoy will develop brown or black spots if the plant suffers from a fungal root disease or a bacterial infection. The leaves will also develop brown scorch marks if the plant sits in direct sun.
Brown Leaf Tips
This can be a symptom of very dry air or fertilizer burn. Try to keep the humidity above 30% and avoid overfertilizing your pothos, especially in winter.
If your pothos NJoy leaves are getting smaller, this could indicate that your plant needs more light, more fertilizer, or that it’s time to repot it. However, it’s normal for the leaves to get smaller if you keep these pothos as a hanging plant for more than two years. The only way to prevent small leaves is by giving the plant a moss pole to climb on.
Your Pothos NJoy can occasionally grow long, bare stems, especially if it’s growing in low light conditions. You can encourage it to produce leaves on the bare stems by applying Keiki paste to the leafless growth nodes.
6 Tips To Make Pothos NJoy Grow Faster
When you bring your Pothos NJoy home, you may notice that it won’t grow any new leaves for the first few months. This is normal because the plant needs time to get used to its new growing conditions. But you can do a few things to help your plant acclimatize and grow faster.
- Give it more light. All plants need light for photosynthesis, the main factor that triggers plant growth. Bright indirect sunlight is ideal for the NJoy pothos.
- Use a nitrogen-rich fertilizer. Nitrogen promotes leaf and stem growth, and it will help your pothos grow longer vines faster.
- Keep it warm. This is a tropical plant, and it will grow best in temperatures between 70°F and 86°F.
- Increase humidity. Although the NJoy doesn’t need a lot of humidity, raising it to around 60% will help increase its growth rate.
- Water correctly. Too much or too little water will stress your plant, resulting in health problems that will stunt its growth.
- Repot regularly. Once every 2 to 3 years should do the trick but always check the roots of your plant first.
The key to success is ensuring your care routine meets all these growing requirements. For example, if your pothos has been living in the same pot for several years, giving it more light and fertilizer won’t make it grow faster. However, moving it to a bigger pot will.
Is Pothos NJoy Toxic?
Pothos NJoy is toxic to cats and dogs. The stems contain calcium oxalate crystals, which can cause difficulty breathing, painful mouth and throat irritations, and gastrointestinal problems. Always keep it out of reach of pets and small children.
Can You Grow Pothos NJoy in Water?
Yes. Using the water propagation method, you can indefinitely grow Pothos NJoy in water. Remember to change the water at least once a week and regularly give it a weak fertilizer dose. But keep in mind that your pothos will grow even slower than they would in the soil.
Does Pothos NJoy Climb?
All Epipremnum plants are natural climbers, including the NJoy pothos. Try growing it on a trellis, or give it a moss or coir pole to climb onto. This will also help the plant grow larger leaves.
But if you don’t have space for plant support, don’t worry. You can also keep the NJoy as a trailing or hanging plant.
What’s the Difference Between Pothos NJoy vs Pearls and Jade?
Both N’Joy and Pearls & Jade are sport varieties of the Marble Queen pothos. The main difference between them is leaf variegation, namely the presence and placement of green speckles.
Pearls and Jade has speckles on both the light green and white leaf sections. The speckles are present on almost all the leaves, forming large, well-defined pattern clusters.
Can Pothos NJoy have speckles? According to the patent images, it can. However, the green speckles and splashes are rare. They only show up on a few leaves and only on the white sections.
