4 easy-care houseplant lessons we learned from YouTube channel Harli G

When you start your plant journey, one of the names that you’ll likely encounter when you search up YouTube tutorials is Harli G. Harli began uploading videos in 2014 and her content now runs the gamut from top plant lists to plant shopping hauls. Occasionally Harli will post about her family and lifestyle, but her posts typically remain devoted to beginner-friendly houseplant guides. Her style tends to be playful and conversational while still being full of helpful information. Over the years, she’s shared valuable advice on her channel with plant lovers everywhere — ahead, we’ve gathered a few of our favorite lessons from her so far.

How you repot your plant matters more than when you do it.

Repotting is an inevitable part of plant parenthood, granted that you have plants that’re growing. One of Harli’s most popular uploads is a video all about how to repot plants. Harli admits that she often repots her plants when she brings them home — that way, she can check the roots and soil to deal with problems immediately. Her methodology for repotting is pretty straightforward: When filling in a new planter, add a layer of soil at the bottom first, or else the plant may not sit at an appropriate height and the root base may flatten. If your plant is already in good soil, there’s no need to remove too much of it. After situating your plant in its new home, add extra soil to fill the sides.

Transplant shock may occur if you’re overzealous about repotting your plant, but being diligent about inspecting your plant can actually help you give it the best care possible.

You probably have household items that can help you deal with fungus gnats and other pests.

Fungus gnats aren’t usually harmful to your plants, but they can be annoying. Harli covers nine different solutions for handling these pesky pests in this video. After discussing fungus gnat life cycles, she dives into tips for prevention. Her recommendations include bottom watering the plant, allowing the soil to dry, and dressing the top soil with pebbles. Fungus gnats prefer laying their eggs in wet soil and feed on rotting organic material, so keeping your soil dry and free from rot is a critical preventative tip. For homemade solutions, she goes through easy-to-access remedies with household items such as vinegar traps and hydrogen peroxide. Other solutions covered include Mosquito Bits, neem oil, and, of course, yellow sticky traps. Another related video where Harli talks extensively about pest treatment is her video on hydrogen peroxide benefits for plants — in this installation, she goes over how this common household item can help cure common plant issues.

Before rushing to find another plant or an expensive pest solution, look to your cleaning cabinet or pantry first, then apply these preventative tips to keep your recovering plant healthy.

It’s fine for your feelings about your plants to change.

This video is all about plants that Harli regrets buying — perhaps one of the things her audience enjoys most is how honest she keeps her channel! Plant enthusiasts may know the feeling of bringing home a plant and falling out of love with it or finding it too much of a struggle. It’s normal for your feelings about your plants to change as they situate inside of your home (or, on the other hand, completely fail to acclimate to your space). Taking note of which plants you don’t love can help you plan future potential plant splurges. In her video, for example, Harli talks about a variegated ZZ plant and moon shadow hoya — she had reservations about these because they didn’t have the level of variegation she wanted but decided to buy them anyway. In the end, she couldn’t revert these plants back to their variegated states.

The lesson to be learned here is that if you plan to buy a plant that isn’t exactly what you want, proceed with caution.

Propagate plants to help make the mother plant look fuller.

In this video, Harli unpacks the process of propagating her lemon-lime maranta to fill it out. Prayer plants can tend to get leggy, so cutting them back can help them grow back more vigorously. Additionally, you can also stick your cuttings back into the soil, as Harli does here. Prayer plants may seem tricky to take cuttings from, but all you need to do is find where multiple stems grow from one stem. Directly cut underneath the bump and put your cutting in water for the roots to grow. After watering the soil, Harli dug holes in her original plant’s soil and stuck the cuttings in them.

If you find your prayer plant (or really, any other plant) looking sparse, take cuttings of it to encourage bushier growth. Additionally, you can also stick the cuttings into the same planter once they root.

Harli G’s casual yet informative videos have made her one of plant YouTube’s mainstays. Whether you’re seeking out beginner plant care guides or pest prevention tips, you’ll find valuable insight from Harli’s channel. If you’re not looking for any information in particular, you can also leave her plant haul and care routines videos on for a soothing viewing experience!

What you need to know about buying plants from big box stores
plants with shopping carts

Recently there has been a stigma against buying plants from the plant sections at big box stores, like the grocery store or your local Home Depot. While most of us probably started collections with plants from these places, you've likely grown suspicious of them since learning more about plants. As with everything, there are pros and cons Here, we dive into why you should or should not buy plants from these big box stores.
The prices of the plants
One of the biggest pros to buying from big box stores is the price. You can find some adorable plants for not too much money and grow your collection quicker. This is also an excellent opportunity for those with smaller budgets to get into growing plants without having to invest a lot of money. However, lower prices mean the plants were probably bought in bulk and aren't as tended to as plants in smaller, more specialized stores. Of course, this isn't an end-all-be-all con, but it's something to remember when taking a gander at these tempting sections of those stores.

Availability of the plants
Although the plants' prices are agreeable, the variety of plants that the bigger stores offer isn't going to be as impressive. Since those stores buy in bulk to lower their prices, they don't have the budget or the capabilities to invest in a wide range of species. So while you might be able to find an affordable palm or ZZ plant, you're not likely to see more rare plants in those stores. But, of course, if this isn't important to you and you love anything green you can get your hands on, then you'll love the affordable plants at big box stores!
In-store care
One of the most significant differences between big box stores and smaller expert stores is the in-store care the plants receive. Generally speaking, big-box stores instruct their employees to water all the plants on a specific day, and they don't cater to the needs of each plant. However, the smaller stores that specialize in plants take the time to understand what the plant needs, like which plants were watered yesterday and don't need to be watered as often. They'll also be able to see issues with a plant and act on it. For example, big box stores don't care if some of their inventory dies, but the smaller stores might pull the plant from the shelf and try to save it.
Healthy plants
In the end, the plants you buy from a smaller store will be healthier because the staff took the time to tend to their needs. In comparison, you might take a plant home from a big box store that's been over- or under-watered and dies the following week by no fault of your own. Additionally, smaller stores will pull plants with pests or diseases and treat their plants regularly to ensure all their plants are healthy.

4 important lessons we learned from Crazy Plant Guy’s YouTube channel
Pilea plant

Alongside channels such as Planterina and House Plant Journal, Crazy Plant Guy is one of the main fixtures on plant YouTube. Based in Toronto, Ontario, Crazy Plant Guy, or Christian Esguerra, is known for his plant care guides, tours, and recommendation lists. His videos are often fun and playful while also full of helpful information for both beginner and seasoned plant enthusiasts alike. Since 2017, Esguerra has been spreading his love of plants with the YouTube community — here are the best lessons he’s shared thus far.

Repotting time is an ideal window for aerating soil and taking cuttings.
While this video specifically covers Esguerra’s (now notoriously gigantic) pilea peperomioides, it includes versatile tips about repotting plants in general. As he repots the pilea plant, he moves it into aerated soil, using a well-draining mix of 50% cacti soil, 45% potting mix, and 5% orchid bark and perlite. He reminds us not to pack in the new soil — keep the mix aerated to prevent root rot. Remember to use the opportunity of repotting your plant to take cuttings, too. Just don’t overdo it, or else you may shock your plant when you transplant it.

Can you grow dracaena from cuttings? Here’s what we know
Close up of dark and light green dracaena leaves

Dracaena is an interesting plant with many unique varieties. It can be either a tree or a shrub, and comes in several different shades of green, and even a few shades of red. This easy-to-care-for tropical plant is a big hit for both indoor and outdoor gardens. If you already have one, you might even be itching for a second, or even third dracaena. Of course you can get an entirely separate dracaena plant, but you can also propagate your own dracaena at home. Not sure how to get started? We’ll help you out with this step-by-step guide!
Why and when should you propagate dracaena?
The why is easy to answer: Because it’s a great way to get more dracaena! Propagation works by cloning the parent plant, often, but not always, through a cutting. The cutting grows into a second, separate plant that is genetically identical to the parent plant. This means you have a second plant of the same type, to plant, give away, or propagate further as you wish.

Your dracaena should be a mature plant when you begin to propagate it, but you can propagate it during any season. It’s easiest to propagate them during spring and summer, when new growth is naturally occurring. However, if your dracaena is an indoor plant, or you live somewhere with hot temperatures year round, you can propagate your dracaena in fall or winter with few issues. Your cutting will just take longer to root.
