Going Green: 4 Easy Houseplants and How to Help Them Thrive
In the Northern Hemisphere, January and February are historically the coldest months of the year. And while Spring might be right around the corner, Old Man Winter has a tendency to hang around well into March and April, especially here in the Midwest. As we await warmer temperatures and look for ways to brighten up our indoor spaces in the meantime, we asked plant pathologist and houseplant hobbyist John Headrick what his go-to houseplants are and his tips for keeping them alive and thriving.
In 1978, John’s mother-in-law gave him and his wife a small cutting from her Boston Fern, and today, the forty-two-year-old fern is healthy, thriving, and more than five feet in diameter—despite many moves around the country and a near-death experience in the late 80s when a power outage during Christmastime caused all the foliage to freeze off. And while John would never consider himself a houseplant expert, we figure anyone who can keep a plant alive for more than four decades has a few tips and tricks from which we could benefit when it comes to keeping our houseplants alive.
Keep reading to discover four easy houseplants you can grow—no matter how green (or brown) your thumb is—and John’s tips on how to keep them alive and thriving in your home.
Houseplants 101 with John Headrick
By their very nature, the following houseplants (minus the succulents) are fairly easy to grow because they tolerate less light. In the wild, these plants would most likely grow on the forest floor or underneath trees, and that’s why they can tolerate indoor conditions. Listed below in order of light-tolerance (from least amount of light needed to most) are four plants I’ve had success with in my home.
I would say, on a spectrum, the philodendron can get by with the least amount of light, and the succulents would need the most because they tend to be Mediterranean kind of plants—their natural habitats being California and the Mediterranean area.
1. Philodendron and Pothos
Similar in appearance, philodendron and pothos can get by with the least amount of light (of these four plants). Because of this, philodendron and pothos are often used in office settings. If you’re new to growing houseplants or have not had success in the past, these are the plants for you!
2. African Violet
Small and relatively slow-growing, African Violets are concentric and bloom over and over again. Plus, they almost always bloom in winter, which means you can have some color indoors during some of the coldest months of the year. If these plants become pot-bound (where the roots take over the majority of the pot), they can grow a shoot, which you can cut off and start another plant. (Our African Violet [pictured], was a cutting from my wife’s aunt, who inherited the plant from her mother.)
3. Boston Fern
A great plant for both indoors and outdoors, Boston Ferns tolerate indoor conditions well and thrive outside during humid Midwest summers. I usually keep our fern (pictured) outside from April to October, bringing it in at the risk of first frost. Plus, our fern is more than five feet in diameter, so by the time April comes around we’re ready for it to go back outside!
4. Succulents
Of these four houseplants, succulents need the most amount of light because they are native to Mediterranean-like climates. These plants are easy to grow together, and they are pretty good about regrowing. For example, a couple of summers ago, a big storm came through and knocked over one of our succulent pots. Some of the stems were in pretty bad shape, but it wasn’t just a few weeks later and they were all sprouting out again.
Tips to Keep Your Houseplants Alive & Thriving
Potting
I normally grow my houseplants in terra cotta pots with a bigger terra cotta saucer underneath. Not everyone might agree with this, but I think houseplants grow better in clay pots versus plastic. However, most people are using it more for decoration than trying to grow something for forty years—so there’s the aesthetics people consider when potting their houseplant—I get that! Also, a good general rule is this: the bigger the pot, the bigger the plant will grow—especially when it comes to the Boston Fern.
Placement in Your Home
In general, west-facing windows tend to work very well at this latitude (Missouri), especially during the winter. A north-facing window doesn’t get enough sun, and a south-facing window—if you have a lot of sunny days and the plant is not a light-loving plant—can scald it. That being said, west or east windows are good, but west windows are my preference. Regarding African Violets, in particular, these plants take a little more light than most people think; so for me they do well in a west window. If you place them in a north window, they will probably be fine—they just won’t be as robust.
It’s also probably best that your houseplants don’t sit right next to vents. However, there’s a balance between the perfect place to grow a plant and where I want it aesthetically. It’s a bit of give and take. Sometimes you just can’t put the plant in the perfect spot because it’s a high-traffic area or it just doesn’t look right.
Indoor/Outdoor Plants
We keep our Boston Fern outside until the first risk of frost, then I bring it in. In our Midwest humidity, ferns really thrive outside in the summertime, and they do like that bit of additional light. I grow it in the shade of a tree or on a porch under the eaves—not in direct sunlight—but it does like the extra light, and it goes crazy in the humidity.
Our succulents go outside from April to October, as well. Once outside, we keep the succulents in full sun, and they love it. That being said, they also require more water during the summer when they’re out in the sun. If we’re going to be gone for the weekend, we do move them to the shade.
Watering
In my opinion, watering is the art of growing houseplants because it’s easy to overwater or underwater. Over time, you will learn learn how much the plant will take and how much it will use. What I’ve found is that the best way to water your houseplants is to let the soil dry out so it feels a little bit dry to the touch and then completely saturate the soil—but not to the point of having standing water. The plants like to go dry, not to the point of wilting, but just to the point that the soil is dried out.
It’s also helpful to get on a watering schedule. For me, I water twice a week: Wednesday and the weekend. I pay attention to how much I water during those two times. If I water mid-week, then I water enough so the soil is dry by Saturday when I water it again. It took time to observe the plant and discover how much water I really need to give it. It also may vary season to season when daylight is shorter or longer. For example, the plant might take less water in February than in the Spring or Fall.
For the Boston Fern, I water the top of the soil and fill up the dish to allow the plant soak up the water. The new shoots like to be moist.
For the African Violet, I simply water the saucer and let the plant soak up the water from the bottom.
Succulents don’t really take a whole lot of water, so I water them once a week or a little bit twice a week. I let the soil get dry, but with succulents I water a little less than saturation. They also take direct sunlight, so if you want something in a south-facing window, that’s where I would put succulents.
Fertilization
It’s important to fertilize your plants, and the easiest way to do it is to add fertilizer to your water. I really like Schultz Plant Food. It’s liquid and comes with an eye dropper, which makes it easy to shoot an eyedropper full into your watering can. I don’t add fertilizer every time I water, but every third or fourth time I’ll put some in there. If you ever see your plant turning yellow, it’s a good indicator that it is not being fertilized.
Pruning
A common misperception among people who aren not used to caring for plants is that once the plants look like they’re dying, they should just be tossed. People are often afraid or timid when it comes to pruning their houseplants. But if you want them to look good, you have to keep pruning them. And while pruning any plant can be intimidating, you simply need to know where the growing point is and just make sure you don’t prune that off.
For African Violets, as the leaves wilt, they’ll tend to wilt at the bottom and you can simply pull them off or cut them off from the bottom. Sometimes, plants wilt or die and it’s not because of whether you cared for it well or not. For example, several years ago, I noticed all the leaves were stunted and deformed on several of my African Violets. At first, I thought it was a virus. After looking it up online, it turned out to be a mite infestation. I started using two different miticides, and eventually the plants began to grow back. The one we have today is a survivor of that mite infestation. Sometimes, though, the health of the plant is just out of your control.
Regarding the Boston Fern, you want to cut out the dead and dying fronds. Because those will get old, turn yellow, and drop leaves—so you want to go ahead and cut them off.
Turning
The secret to growing a perfectly round plant? Simply turn it a quarter turn once a week. That way the whole plant shares in the sunlight. If you never turn your plant, they’ll start to grow toward the sunlight.
