Areca Palm: February Houseplant of the Month

Standard

The areca palm or butterfly palm (Dypsis lutescens) projects a sense of calmness on the entire décor. The palm has no central stem at first: the reed-like petioles all emerge directly from the soil and grow upwards forming numerous light green narrow pointed leaflets. The fronds spread outwards in an attractive green fountain shape that looks cheerful, creates plenty of atmosphere and also lends a touch of grace to the interior. Only mature specimens show bamboolike stems. 

Research by NASA also shows that the areca palm has an air-purifying effect in the home and help create good humidity—another good reason to grow it.

Origin

The Areca palm is a member of the Arecaceae or palm family, which also includes all true palms. The plant had been sold for generations under the botanical name Chysalidocarpus lutescens. However, recent studies show that the Madagascar native is closely related to other Dypsis species of that island and so was renamed Dypsis lutescens. The epithet lutescens means yellowish, a reference to the yellow coloration of the petioles of mature specimens.

Curiously, in spite of the common name areca palm, this plant is not at all closely related to Areca catechu, the betel nut palm, famous for its narcotic nut that is chewed in South Asian countries, leading to euphoria, but also bright red saliva and permanently blackened teeth. The name “areca palm” was given to D. lutescens due to an error in identification over a century ago and has stuck ever since.

Areca Palm Assortment

There is just one species of areca palm, but it is sold in various sizes, from young plants in small pots with only one stem to clumps (it naturally produces offsets) of larger plants. It can range in size height from about 40 cm (16 inches) to 3 m (10 feet). The larger the plant, the more you can expect to pay. Outdoors in the tropics, it can reach 12 m (40 feet) in height. 

What to Look for When Buying an Areca Palm

  • First check that you have the right species. Younger plants in particular can sometimes be confused with kentia palms (Howea forsteriana). The difference can be most easily seen in the petioles at the base of the fronds. Kentia petioles are green and surrounded by brown fibres while areca petioles are smooth and bear red spots. Also, the areca palm’s fronds are thinner and narrower than a kentia’s. The species particularly differ in terms of price (areca palm is considerately cheaper), so it’s worth paying close attention.
  • Also check for a pleasing proportion between the pot size, thickness and height of the plant. Sometimes areca palms are underpotted to save on shipping costs and that can lead to problems later.
  • Before purchase, make sure that your areca palm is free of mealybugs and scale insects. These are hard for houseplant lovers to get rid of. 
  • The plant can also suffer from red spider mites, identifiable by a greyish look to the fronds. They mostly pop up when the palm is kept in overly dry air.
  • Plants should be free of yellow leaves or brown leaf tips, caused by dry air ou underwatering. 
  • Black spots, particularly in older plants, often indicate a too high salt concentration in the potting soil, which can be corrected by leaching the root ball with water.
  • Make sure your plant has not been subjected to cold temperatures which cause dark spots on the leaves. It should have been kept at 12°C (54°F) or higher during shipping. 
  • Although it naturally produces offsets over time, the areca palm is propagated from seed. Thus, young plants already growing in dense clumps were likely produced by sowing many seeds in the same pot.

Care Tips 

  • Wrap the plant for the journey home during cold weather.
  • The areca palm requires a spot in bright light. However, it’s best to avoid intense daylong sunlight in the summer months.
  • The bigger the plant is, the easier it is to look after: just adjust the watering to its size. Water the plant regularly, avoiding cold water, so that the potting soil never dries out completely.
  • In most homes, you’ll need to increase the atmospheric humidity during the winter, as central heating dries the air. It might be worthwhile using a room humidifier… something that will benefit most other houseplants as well.
  • Fertilize only very lightly, with an all-purpose fertilizer, from spring through early fall.
  • As the plant grows, it will produce new fronds from the top, while older ones (those at the base of the plant) will turn yellow. When this happens, simply pull them off. 
  • You can place your areca palm on the patio or balcony in the summer, giving it a tropical look, provided that temperatures don’t drop below 12°C  (54°F). Areca palm are tropical plants and don’t cope well with cold.
  • You can also put your areca palm outdoors on a rainy summer day to help remove dust and grime.

Display Tips 

Areca palms are ideally suited for the modern trend toward plants with light, airy foliage that soften external influences. Opt for neutral cache-pots such as matt glass, matt ceramic or smooth polished wood. The more serene the look, the more calming the impact of the display will be. 

Larger specimens can be used on their own, while the smaller plants look more attractive in a row or as screening.

Try setting your areca palm behind a screen of tulle or very thin rice paper, then use soft backlighting to reinforce the areca palm’s calming, buffering effect, creating a striking filter for your décor.

15 Not-So-Easy Houseplants

Standard

20180127A Spathiphylium www.gardeningknowhow.com.jpg

This peace lily (Spathiphyllum) is suffering from chronic underwatering: a typical problem with this species. It’s not as easy to grow as many people claim. Source: http://www.gardeningknowhow.com

In preparing yesterday’s article, 15 Easy Houseplants for Beginners, I, of course, took a look at other websites to see what they suggested. (No, that’s not plagiarism: it’s called “research!”) But I must admit I was surprised by some of their suggestions, sometimes even horrified!

After all, the purpose of writing such a piece is to showcase indoor plants that are particularly easy to grow, ones that even the most fledgling gardener could grow without difficulty. But these other lists included plants that I would never have thought to include among easy-to-grow plants, plants whose flaws rather make them a challenge to keep alive unless special precautions are taken. In fact, plants I would normally warn people about.

Let’s take a look and see.

Why Do These Not-So-Easy Plants Fail?

20180127B Aloe vera HC.jpg

Good light is very rare in most homes, leading plants to suffer from etiolation, like this unfortunate Aloe vera. Source: laidbackgardener.com

Sometimes the problem is simply that the plant needs really good light. I would never recommend such a plant as an easy-to-grow houseplant, not considering the horrible indoor lighting conditions most people have. Even fairly experienced indoors gardeners tend to overestimate the quality of light they have available to them. Imagine beginners!

The average dwelling is not a greenhouse, with light from above and on all sides. In most rooms, it only comes from one side, through a vertical window. And most readers of this blog live in temperate climates, where sun may be fairly abundant indoors in the summer, but miserably lacking in winter, what with short days and weeks of cloudy conditions. So even right in front of your largest window, there is often not enough light for many plants, especially if it’s on the north side of our home (in the Northern Hemisphere, that is). Imagine what conditions are like in the back of the room! That’s why, in my opinion, only plants that can tolerate low light can be considered easy-to-grow houseplants.

And they must also be not only capable of putting up with low light, but of doing for long periods. This belief that some many commercial nurseries seem to have—that 8 weeks is an acceptable lifespan for a houseplant (see The Life Expectancy of Houseplants) and therefore that a plant that can last 8 weeks in near darkness can be classified as a low-light plant—is just nonsense! According to my way of thinking, to be shade-tolerant, it always has to be able to grow and even thrive in shade, not just for a few weeks, but years.

In other cases, not-so-easy houseplants are too sensitive to dry air for the average home, too subject to insects or diseases, naturally short-lived or have special requirements that go beyond regular maintenance and thus complicate their care. If you can’t just resume a plant’s care by saying “put it in your living room and water it when its soil dries out,” it’s not an easy-to-grow houseplant.

15 Not-So-Easy Houseplants

Here are 15 indoor plants that appear on other people’s list of easy houseplants. In general, no, they aren’t extremely difficult to grow, at least not for a gardener with experience, but, for one reason or another, you just can’t expect a beginning gardener to succeed with them.

1. Boston Fern (Nephrolepis exaltata ‘Bostoniensis’ and other cultivars)

20180127K Nephrolepis exalatat www.amazon.com

This fern tolerates dry air better than most other ferns, which is great, but is far less tolerant of shade. In fact, it really only does well when put in a pretty sunny location … and that’s not what most people do.

The Boston fern used to be a far easier houseplant before the middle of the last century, one our grandparents often grew to astounding sizes. What changed? Our indoor environment! We heat our homes more, yet this plant likes a cool winter. As a result, it often gets smaller and thinner over time instead of plumping up like a happy houseplant should do.

2. Bromeliads (Aechmea, Guzmania, Tillandsia, Vriesea, etc.)

20180127C Broméliacées www.orchardnursery.com.jpeg

Various bromeliads. Source: www.orchardnursery.com

These plants are totally charming and can last for months in a typical house. But usually, they’re sold in bloom … and that’s a problem, because they die after flowering! And it’s just plain unfair to hoist a soon-to-die plant off on a rank beginner.

True enough, with rare exceptions, bromeliads will produce at least one “pup” (offset) before they go, a pup that will flower in its turn … a few years down the road! Understanding that is a lot to ask of a novice gardener. They’re more likely to become discouraged when they see the mother plant deteriorating bit by bit.

Air plants (various species of Tillandsia) need such different care from other houseplants, they need to be treated separately. Source: cdn.shopify.com

As for air plants (Tillandsia spp.), a subgroup of bromeliads, their situation is somewhat different. First, they are rarely sold in bloom, but rather as unrooted plants you’re supposed to hang from the ceiling or deposit on or glue to an indoor arrangement of some sort. The fact that they need totally different treatment from any other houseplant automatically makes them complicated. They have to be watered, not by humidifying the soil they grow in (because they don’t grow in soil!), but by soaking them in water or spraying them regularly. Of course, they also need bright light and air movement. I wouldn’t say air plants are necessarily difficult to grow, but they aren’t easy either. If you want to know more about growing air plants (Tillandsia), read How to Make Your Air Plants Thrive.

3. Butterfly Palm or Areca Palm (Dypsis lutescens, syn. Chrysalidocarpus lutescens)

 

20180127N Dypsis lutescens www.ikea.com.jPG

This plant’s susceptibility to spider mites makes it a challenge to grow. It often breezes through summer in fine shape, then, with the arrival of fall and drier indoor air, spider mites show up and soon start to take over. You never seem to be able to get rid of them entirely!

The butterfly palm is not the only palm with this problem, by the way. As a result, few are good choices for beginners.

4. Cacti and Succulents

20180127D Succulentes thesucculentsource.com.jpg

Cactus and succulents: great choices if you have full sun, but most aren’t given nearly enough light and go downhill slowly once you bring them home. Source: thesucculentsource.com

There are hundreds of houseplants in this category and most are not at all hard to grow … if you have a lot of light. Indeed, most even prefer full sun (there’s not much of that in the average home)! Sadly, our homes are simply much more shaded than most people imagine. As a result, I see cactus and succulents in various states of decline wherever I go. Yes, they may be still alive, but barely.

20180127E Opuntia étiolé pistilsnursery.com.jpg

This is not a happy cactus (Opuntia). It’s severely etiolated due to insufficient light. Move it to a sunny window, fast! Source: pistilsnursery.com

Of course, among the wide variety of succulents, there are some that tolerate some shade and are therefore better choices for beginners, such as aloes (Aloe spp., including A. vera), haworthias (Haworthia spp.), gasterias (Gasteria spp.), succulent euphorbias (Euphorbia spp.) and, of course, the oh-so-popular jade plant (Crassula ovata) … but they still need a location that receives at least 5 hours of indirect light per day, therefore a location very close to a window. You have no idea of how many very sad, floppy jade plants I see, alive but struggling, in people’s homes. Their weeping stems seem to say, “Please put me out of my misery!”

Also, many beginner gardeners lose their succulents over the winter because they water too much. When you grow succulents, it is very important to let the soil dry out before watering again. Doubly so when light is low, as is the case in winter. Often, at that season, cacti and succulents only need to be watered once a month, yet the average indoor gardener tends to water everything they grow once a week. You can just feel the rot settling in!

5. Calathea (Calathea spp.)

20180127F calathea-zebrina www.planten-kopen.com.jpg

This is a prime example of a plant that “holds” for several months, especially when you buy it in the spring or summer, but ends up going rapidly downhill in the winter. It’s supersensitive to dry air (a common problem indoors in winter) and really has a hard time dealing with the lower light winter brings. The result is a great plant that soon goes bad.

6. Croton (Codiaeum variegatum)

20180127I Codiaeum variegatum garden.org.jpg

Most crotons (Codiaeum variegatum) drop their leaves one after the other when you move them into your home and soon come to look like this. How could anyone possibly call them easy to grow? Source: garden.org

Recommending crotons to beginning gardeners is out and out horrific. This plant has a terrible reputation among gardeners for its ability to quickly go to pieces when you bring it home. The problem is that it simply doesn’t tolerate changes in its growing conditions, so when it goes from the full sun and high humidity of Florida or Costa Rica to a dingy apartment where the air is drier than the Sahara, it starts losing leaves. And more and more fall off as time goes on. Now, if you know how to properly acclimatize it, you can get it to adapt perfectly well to average indoor conditions, but it’s hardly a plant you’d want to entrust to a beginning gardener! Shame on anyone who promotes the croton as an easy-to-grow plant!

7. English ivy (Hedera helix)

20180127L Hedera helix www.amazon.com_.jpg

Typically, this plant is easy to grow in spring and summer, then fall comes and it falls apart. The problem is that when the air gets drier, as it almost always does during the heating season, spider mites appear out of nowhere and quickly kill it. Few plants can be covered with spider mites as quickly as English ivy.

8. Peace Lily (Spathiphyllum)

20180127Q Spathiphyilum amazon.com.jpg

Like most peace lilies (Spathiphyllum) sold these days, this one is severely underpotted and will quickly go into decline unless it receives very good care. Source: amazon.com

Sure, this plant is easy enough in general, but it quickly takes on a wilted lettuce look when it runs out of water and each time it does, the next recovery is less and less successful. It always seems to be drastically underpotted when it reaches your local garden center, which, of course, compounds the problem. Quite often, it must be watered more than once a week just to survive! Repotting it into a bigger pot as soon as you get it home will help, but if you’re one of those people who tend to forget to water every now and then, the peace lily is definitely not a wise choice for you!

9. Norfolk Island Pine (Araucaria heterophylla)

20180127R Araucaria heterophylla amazon.com_.jpg

Severely overcrowded, this pot of Norfolk Island pines (Araucaria heterophylla) won’t likely live very long. Source: amazon.com

Few Norfolk Island pines survive more than a few months in the average house. Their need for fresh, humid air while our homes are hot and dry in the winter ends up killing them. Plus, the trend these days is for nurseries to stick a half a dozen or so young plants in the same pot so it will look fuller … and that only means there are more roots competing for the water you apply, with fatal results. Under good conditions, and when reduced to one or two plants per pot, this indoor conifer can live for decades. Still, I wouldn’t offer it to a rank beginner!

10. Peperomia (Peperomia spp.)

20180127O Peperomia caperata Emerald Ripple Lazaregagnidze, WC.JPG

One of many types of peperomia. Here, Peperomia caperata ‘Emerald Ripple’. Lazaregagnidze, Wikimedia Commons

There are too many species (over 1500!) of peperomias for me to make more than a vague generalization about them, but even so, many of the commercially available varieties are prone to rot if overwatered … and who doesn’t apply just a bit too much moisture every now and then? Typically, peperomias grow well at first and its owner is very pleased with the result, then, months later, they suddenly keel over and die. It can be quite a shock to see them go from healthy and happy to dead and rotting in just a few days.

11. Prayer Plant (Maranta leuconeura)

20180127P Maranta leuconeura erythroneura carlosbato-arte.blogspot.ca.jpg

Yet another plant that gives encouraging results at first, especially if you buy in spring or summer, when there is more light in our homes and the air is generally humid, but the low light and dry air of winter cause it to die back gradually. By spring, it’s often only the shadow if its former self, if indeed it’s still alive.

12. Rubber Plant (Ficus elastica)

It’s unfortunate that nurseries continue to insist that the rubber plant is a low-light plant when, on the contrary, it requires a lot of light, even full sun. True enough, it “holds” quite well in shady spots, sometimes for six months or more, but once it’s used up its energy reserves, leaves start to drop one by one until death ensues.

13. Schefflera or Umbrella Tree (Schefflera actinophylla, syn. Brassaia actinophylla)

20180127S Schefflera actinophylla www.homedepot.com.jpg

This is the larger of the two common scheffleras, the one with big, shiny, umbrella-like leaves, not the dwarf schefflera (S. arboricola), a much, much easier plant to grow. Like English ivy and the golden cane palm, its susceptibility to spider mites makes it difficult to maintain in good shape for very long.

14. Spineless Yucca (Yucca gigantea, Y. elephantipes and Y. guatemalensis)

20180127T Yucca gigantea www.waitrosegarden.com.jpg

Spineless Yucca (Yucca gigantea). Source: www.waitrosegarden.com

Generally sold as a small tree with a brown, woody looking trunk with tip cut off and two to four tufts of lanceolate leaves at the top, the spineless yucca is a superb plant, but it shares the rubber plant’s bad habit. That is, it “holds” well, for months at a time, even in shady spots, then, when it has spent all its stored energy, it launches into a long decline. It can sometimes survive (one can hardly say “live”) for two or three years under a typical home conditions, but, unless it’s right in front of a sunny window, becomes more and more etiolated and less and less beautiful over time, with yellowing leaves galore!

15. Weeping Fig (Ficus benjamina)

20180127J Ficus benjamina goodtogrow.files.wordpress.com.jpg

Unless it is properly acclimatized, the weeping fig (Ficus benjamina) starts losing leaves and is soon in decline. Source: goodtogrow.files.wordpress.com

Okay, this plant can tolerate the shade and dry air of our homes and can even live decades under such conditions, but, as was the case with the croton, this is only true if you acclimatize it well beforehand. Otherwise, the leaves begin to fall almost as soon as you bring it home and it soon looks dreadful. Many more people manage to kill their weeping fig than succeed in keeping it healthy and happy. Read Stop Your Weeping Fig From Losing Its Leaves to learn how to acclimatize it.


There you go! 15 plants that may be interesting for gardeners who have a bit of experience, but which I would certainly not to offer a wet-behind-the-ears gardener. Definitely not “easy-to-grow houseplants,” in spite of what some websites claim!20180127A Spathiphylium www.gardeningknowhow.com
