Here along the Front Range, our beautiful Colorado sunshine and high-altitude climate make indoor gardening a true adventure. Our climate is so unique, standard internet advice can backfire inside our homes. If you have ever been told to water your plants on a strict calendar schedule or drop ice cubes into your orchids, you have already run into the world of houseplant folklore.
The internet is absolutely packed with well-meaning plant rules, but many of these deeply ingrained "laws" do your green friends more harm than good. Whether you are a brand-new plant parent trying to keep your first pothos alive, or a seasoned veteran with a living room jungle, it is easy to get caught up in bad information.
Today, we are putting on our myth-busting hats to separate fiction from science-backed facts. Grab a cup of coffee, look at your greenhouse collection, and let’s dive into the truth behind these common houseplant tales:
Myth #1. Bigger pot = Faster growth
It seems logical: give the roots maximum room, and the top of the plant will explode with growth. However, the exact opposite happens. When you place a small plant into an oversized container, the massive amount of extra soil holds on to way more water than those tiny roots can drink. This leaves the soil perma-soggy, suffocating the roots and inviting root rot. Your plant will divert all its energy underground to try and fill the void, completely halting any new leaf or stem growth.
Truth
Most plants prefer being a little snug in their quarters. Only upgrade your pot size by 1 to 2 inches in diameter at a time. This small stepping up in size allows the plants roots to fill
the space comfortably without excess moisture build up.
Myth #2. Low Light Plants Can Survive Anywhere
We have all seen the beautiful home décor photos featuring a lush snake plant or a dark green ZZ plant tucked deep inside a windowless bathroom or a shadowy hallway corner.
Labeling these varieties as "low light plants" is highly misleading.
Truth:
In reality, these plants are simply low-light tolerant, meaning they possess a high threshold for survival and die very slowly compared to others. No plant can grow without light; light is their food. In a dark corner, a plant stops growing, sheds its lower leaves, becomes leggy, and easily succumbs to overwatering because it lacks the energy to process moisture.
If you cannot comfortably read a book in that corner without turning on a lamp, your plant cannot feed itself. For dark spots, rotate your greenery closer to a bright window every few weeks, or pick up a dedicated LED plant grow light from our shelves. Poor / low light exists in corners that do not face windows, in areas more than about 8 feet away from the source of light, or even directly in front of windows darkened by buildings or other obstructions.
Myth #3. The Annual Repotting Routine
Many new plant parents assume that spring cleaning must include repotting every single green resident into a larger home. However, forcing a plant into a new pot before it is truly ready is an easy way to stall its growth entirely.
Truth
Don't let the calendar dictate your schedule. Many slow-growing varieties—like Hoyas, Snake Plants, and Spider Plants—love a snug fit and prefer to stay compact in the same pot for two to three years. If you move them to a bigger space too soon, they will stop pushing out beautiful new leaves above the soil and spend all their energy growing roots to fill the void.
Your plants will tell you when they are genuinely ready for an upgrade. Look for real signs of overcrowding, like roots swirling out of the bottom drainage holes, water running straight through without soaking in, or the plant pushing itself up out of the container. If it looks happy, compact, and healthy, leave it be! Instead of upsizing, simply refresh the top couple inches of soil with a nutrient-rich potting blend to feed the plant without disturbing the sensitive root ball.
Myth #4. River Rock / Gravel in the Bottom of the Pot for Drainage
This is perhaps the oldest myth in the book: if your pot doesn't have a drainage hole, or if your pot is too large – just layer an inch of gravel, rocks, or broken pottery shards at the bottom to create a drainage reservoir.
Truth
Physics proves this method has the exact opposite effect. Water does not easily move from a fine texture (potting soil) into a coarse texture (rocks) until the soil is completely
saturated. This creates a hidden, stagnant pool of water right where the soil meets the gravel, raising the perched water table straight into your plant's root zone and drowning them.
No Drainage? The Advanced Hack That Does Work: If you absolutely must use a decorative pot without a drainage hole, drop the heavy gravel and switch to LECA (Lightweight Expanded Clay Aggregate). Because LECA consists of baked clay balls, it is incredibly lightweight and won't make your pots heavy.
How to do it right: Lay down a 1-to-2-inch layer of LECA at the bottom of the container. Next, place a cut piece of breathable mesh (like plastic window screening or landscaping fabric) directly on top of the LECA before adding your potting soil. This mesh acts as a physical barrier, preventing the soil from sliding down and clogging up the reservoir below.
The Catch: While this creates a functional "false bottom" reservoir, remember that the water still has nowhere to escape. You must be incredibly careful with your watering can. Only add a measured, conservative amount of water, so you don't overflow your hidden LECA reservoir and flood the soil above.
Pot’s Too Large?
How to Shrink Your Pot: Pour a thick layer of LECA into the bottom of the oversized planter until the remaining space is the perfect size for your plant's current root ball. Lay your
breathable mesh over the clay pebbles and then add your potting soil on top.
Why it Works: The LECA fills the empty structural space without holding onto a massive, dangerous blanket of soggy soil around your plant's roots. It keeps the root environment nice and compact, while the mesh ensures your soil doesn't wash down into the pebbles. It is the ultimate design hack for using big, beautiful pots on small plants.
Myth #5. Calendar Watering V. Intuitive Watering
"Water your plants every Tuesday" or “Sunday is my watering day” this way of watering can quickly become a recipe for disaster, especially along the Front Range.
Truth
Plants do not keep a calendar, and their thirst levels change constantly based on external factors. A sunny, windy week in July will dry out your soil significantly faster than a gloomy, snow-heavy week in January. Factors like indoor heating, air conditioning, and pot material change how fast water evaporates. Stick to a strict schedule, and you will inevitably overwater in the winter and underwater in the summer.
Throw away the schedule and use your hands. Push your finger 1 to 2 inches deep into the soil. If it feels dry and dusty, it is time for a thorough watering. If it feels cool and damp, leave it alone and check back in a few days.
Myth #6. Watering With Ice Cubes
Using ice cubes to water orchids or sensitive tropical plants is a popular internet shortcut designed to prevent overwatering, but it ignores the biological origins of your plants.
Truth
Many houseplants originate from warm, humid rainforests. Dropping freezing ice cubes directly onto the soil shocks the root system, causing root dieback, tissue damage, and premature leaf or flower drop. A couple of melting ice cubes rarely provide enough water to saturate the entire root zone, leaving the bottom roots completely parched while the top roots freeze.
The Real Way to Avoid Overwatering: Overwatering isn't about giving your plant too much water at one time; it is about watering too frequently or letting the soil stay constantly soggy. To thrive, tropical plants need a thorough drenching that saturates all the soil, followed by a period of drying out.
When to Water: Instead of counting ice cubes, look at the soil and the plant itself. Push your finger 1 to 2 inches deep into the soil. If it feels cool and damp, leave it alone. When it feels dry and dusty, your plant is ready for a drink. You can also watch for early signs of thirst, like slightly drooping leaves or a pot that feels unusually light when you lift it.
The "Thorough Drench" Method: Take your plant to the sink and pour room-temperature water evenly over the soil until it runs freely out of the bottom drainage holes. This ensures
every single root gets an even drink and flushes out harmful built-up fertilizer salts. Let the pot drain completely for 10 minutes before putting it back on its saucer so it never sits in stagnant water.
Myth #7. Outdoor Summer Vacation Means Automatic Indoor Pests
As our days warm up it is incredibly tempting to give your houseplants a "summer vacation" on the patio to soak up that bright Colorado sunshine. But many plant parents
hesitate, paralyzed by the fear that bringing them back indoors in the autumn will automatically invite an infestation of aphids, spider mites, or fungus gnats into the house.
While it is true that nature has bugs, you do not have to banish your plants to a life indoors just to avoid pests. In fact, moving your plants outside exposes them to nature's very own pest control team. Outdoor spaces are filled with beneficial predators like ladybugs, lacewings, and predatory wasps that actively hunt and eat the bad bugs for you!
The real magic of moving your plants outside comes down to visibility. Inside our homes, the directional lighting and cozy corners can make it easy to miss the early signs of a pest
problem. But the brilliant, full-spectrum Colorado sunlight acts like a natural spotlight.
When you take a plant out onto the patio, that bright outdoor light instantly brings awareness to anything hiding under the leaves or along the stems. It acts as an early warning system, allowing you to catch and treat a potential issue out on the deck before it ever has the chance to turn into a major headache inside your home.
The Truth
Outdoor summer growth is incredibly beneficial, and the natural predators outside help keep your plants safe. Plus, the bright sun makes it easier than ever to inspect your
collection.
The "Summer Checkup" Protocol: The day you move your plants outside, take advantage of that bright outdoor light. Give them a rigorous, top-to-bottom visual inspection under the full sun. Look closely at the stem joints and the underside of the leaves. If you spot anything suspicious, a quick blast with the garden hose is often all it takes to wash the pests away.
The "Welcome Home" Fall Clean: When the summer season winds down and it's time to bring your plants back inside, use that bright outdoor light one more time for a final checkup. Give the foliage a good rinse and treat the soil and leaves with a natural pest preventative like insecticidal soap or neem oil—both of which you can easily grab at The Flower Bin.
Just because a plant loves the outdoor air doesn’t mean it wants full, direct Colorado sun! Our high-altitude Front Range sunlight is incredibly intense and will sunburn indoor foliage in a matter of minutes.
To give your plants the ultimate summer vacation without the crispy leaves, follow these placement guidelines:
Covered Patios & Porches: This is the sweet spot! A covered north- or east-facing porch provides excellent bright, indirect light while protecting your plants from the harsh midday glare.
Dappled Tree Shade: Placing your plants under the canopy of a large backyard tree mimics their natural rainforest environment, giving them a perfect mix of shifting light and shade.
Protection from the Wind: Longmont is famous for sudden afternoon wind gusts. Keep your pots tucked against the house, behind a privacy screen, or nestled together so they
don’t tip over or suffer windburn.
The "Slow Introduction" Rule: No matter where they end up, acclimate your plants slowly. Start by putting them in deep outdoor shade for just a few hours a day, gradually increasing their outdoor time over a week so they can adapt to the higher UV levels.
