The 3 Ways to Water a Houseplant (and Why It Matters)
If you're scared of accidentally killing your new plant, take a deep breath—you're already doing the most important thing by learning how to water it. Most plants don't die because their owner forgot. They die because of how the water was given. Good news: there are only three methods to learn, and you don't need to memorize a single fancy Latin name.
Here are the three ways to water a houseplant:
- Top watering — Pour water onto the soil from above until it drains out the bottom. The classic method you already picture in your head.
- Bottom watering — Set the pot in a dish of water and let the roots sip it up from the drainage holes. Great for thirsty roots and fussy leaves.
- Soaking — Submerge the whole pot in water for a few minutes, then let it drain. Best for plants that have dried out completely.
Why does the method matter? Because the how affects your plant just as much as the how often. The right technique helps roots grow strong, keeps leaves from rotting, and stops you from over- or under-watering.
Don't worry about choosing right now—we'll give you a simple rule to match each plant to its method a little later.
Top Watering: The Default for Most Plants
If you're nervous about getting this wrong, take a breath—top watering is the easiest method to learn, and it's the right choice for most plants you'll bring home. It's exactly what it sounds like: you pour water onto the top of the soil.
How to do it
- Pour slowly and evenly over the soil, not just in one spot.
- Keep going until water runs out the drainage holes at the bottom.
- Let it finish draining, then empty the saucer so the roots aren't sitting in standing water (that's what leads to root rot).
That's it. The "water until it drains" step is the trick that tells you the whole root ball got a drink—not just the top layer.
Best for
Most leafy houseplants love this method, including:
- Pothos — very forgiving, great first plant
- Philodendron — easygoing and quick to recover
- Peace lily — even tells you when it's thirsty by drooping
The most common mistake
Giving a quick, shallow splash. A little water on top looks like you watered, but it never reaches the roots—so the plant stays thirsty. Always water enough to see it drain out the bottom.
Bonus: Watering thoroughly until it drains also flushes out salts that build up from fertilizer over time, keeping the soil healthier for your plant.
Bottom Watering: For Fussy Leaves and Forgetful Waterers
If the thought of watering "wrong" makes you nervous, bottom watering is your friend. Instead of pouring water on top, you let the plant sip it up from below at its own pace. It's hard to mess up, and it's gentle on the plants that sulk when their leaves get wet.
How to do it
- Fill a tray, bowl, or sink with about 1-2 inches of room-temperature water.
- Set your pot (it must have a drainage hole) into the water.
- Wait 15-30 minutes while the soil drinks from the bottom up.
- Lift the pot. If the top of the soil feels damp, it's done. Let it drip, then put it back.
Best for
- African violets – they hate water sitting on their fuzzy leaves.
- Ferns and other humidity-lovers.
- Any plant where wet leaves lead to spots or rot.
Bottom watering is also a lifesaver when soil gets dry and crumbly. Once soil pulls away from the pot's sides, water poured on top just runs straight through without soaking in. Watering from below lets the soil slowly soak up moisture and "reset."
Why it builds stronger roots
When water sits at the bottom, roots grow downward to reach it. That gives you a deeper, sturdier root system over time, instead of shallow roots crowding the surface.
Common mistake: leaving the pot soaking too long. More than 30-45 minutes and the soil gets soggy, which can lead to root rot. Set a timer on your phone so a forgotten pot doesn't turn into an overwatered one.
What to do if the top stays dry: give it another 10-15 minutes, or add a small splash on top to finish the job.
Soaking: Reviving Thirsty or Bone-Dry Plants
If you forgot to water for a while and the soil looks cracked or pulled away from the sides of the pot, don't panic—you probably haven't killed your plant. This is exactly what soaking is for.
When soil gets bone-dry, it actually starts to repel water. Pour from the top and it just runs straight down the sides and out the drainage hole, leaving the roots dry. Soaking fixes this by giving the dry soil time to slowly drink the water back in.
How to soak a plant:
- Fill a sink, bucket, or bowl with a few inches of room-temperature water.
- Set the pot in the water so the bottom 1–2 inches are submerged.
- Wait until you stop seeing air bubbles rise to the surface (about 15–30 minutes). That means the soil is done drinking.
- Lift the pot out and let it drain fully before putting it back. Never leave it sitting in water.
Best for:
- Plants whose soil has shrunk away from the edges of the pot
- A wilted, neglected plant that needs a rescue
Rescue tip: If your plant is droopy and the soil is rock-hard, give it a full soak, then move it out of direct sun for a day or two while it recovers. Most plants perk back up within a few hours.
One warning: soaking is a rescue tool, not a routine. Doing it every week keeps the soil too wet and can rot the roots. Once your plant bounces back, go back to your normal watering method.
Which Method for Which Plant? A Simple Cheat Sheet
Don't worry about memorizing all of this. Pin this section, glance at it on watering day, and you'll be fine. Here's the easiest rule to remember:
Fuzzy or hairy leaves? Bottom water. Everything else? Top water. Water sitting on fuzzy leaves can cause spots and rot, so those plants drink from the bottom.
Here's your quick-reference card:
| Plant | Best Method | Forgiveness | Watering |
|---|---|---|---|
| Pothos | Top | Very forgiving | When top 1–2 inches of soil feel dry |
| Snake Plant | Top | Super forgiving | When soil is fully dry (about every 2–3 weeks) |
| Succulents | Top | Forgiving | When soil is bone dry; less in winter |
| Ferns | Top (or soak if dried out) | Less forgiving | Keep soil lightly damp, never soggy |
| African Violets | Bottom | Less forgiving | When top of soil feels dry |
When to switch it up:
- Winter: Plants drink less, so water less often. Wait an extra few days and check the soil first.
- Bone-dry pothos or fern? If water runs straight through and the soil pulls away from the pot, give it a 15–30 minute soak instead of top watering.
- Yellow, mushy leaves? You're overwatering. Let the soil dry out more before the next drink.
Pet parents: Pothos, snake plants, and many succulents are toxic to cats and dogs, while African violets are pet-safe. Check the ASPCA list before placing any plant within reach.
Beginner Watering Mistakes to Avoid
Good news: most "dead" plants are just overwatered, and that's an easy habit to fix. If you've made any of these mistakes, don't panic, just adjust and move on.
- Watering on a set schedule. Your plant doesn't drink on a calendar. Skip the "every Sunday" rule and check the soil first. It may need water sooner some weeks and later in others.
- Letting pots sit in water. A saucer full of water keeps the roots soaked, which leads to root rot. Pour out any extra water 15 minutes after watering.
- Using pots with no drainage holes. Without a hole at the bottom, water has nowhere to go. Choose pots with drainage, or pop a plastic nursery pot inside a pretty cover pot.
- Skipping the finger test. Before you water, push a finger about two inches into the soil. If it feels damp, wait. If it feels dry, go ahead and water.
Fix these four things and you'll dodge the most common plant killers.
FAQ
How do I know if my plant needs top or bottom watering?
Match the method to the plant. Top watering (pouring water over the soil) works for most houseplants and is great when you want to flush out built-up salts. Bottom watering (setting the pot in a tray of water so the soil soaks it up) is best for plants that hate wet leaves or crowns, like African violets, succulents, and snake plants, or for soil that has gotten so dry it repels water. If your plant's leaves get spotty or rot easily when they're wet, choose bottom watering. If you're not sure, top watering is a safe default—just make sure your pot has drainage holes.
Is bottom watering better than top watering?
Neither is 'better'—they're good for different situations. Bottom watering helps the roots drink evenly, keeps leaves and crowns dry, and is forgiving if you tend to underwater. Top watering is faster, mimics rain, and rinses away mineral salts that build up in the soil over time. A simple routine many beginners like: bottom water most of the time, then top water once a month or so to flush the soil. Use whichever keeps your plant happy and fits your schedule.
How long should I leave a plant soaking?
For bottom watering, set the pot in a few inches of water and leave it for about 10 to 30 minutes—small pots need less time, large or very dry pots need more. The soil is done when the top feels moist to the touch. Then lift the pot out and let it drain fully so it isn't sitting in water. Don't leave a plant soaking for hours or overnight, because constantly soggy soil can cause root rot. If the top of the soil is still dry after 30 minutes, top water it lightly to finish the job.
Can I bottom water any plant?
Almost—but the pot must have drainage holes, because that's how the water gets in. Bottom watering works well for African violets, succulents, snake plants, pothos, peace lilies, and most common houseplants. It's not ideal for very large or heavy pots that are hard to lift, or for plants in pots with no drainage. It also won't rinse out mineral salts, so plan to top water occasionally to flush the soil. If a plant looks like it isn't drinking from the bottom, check that the hole isn't blocked and top water instead.
How often should I water my houseplant?
Skip the calendar and check the soil instead—most beginner-friendly houseplants like to dry out a bit between waterings. Stick your finger about 1 to 2 inches into the soil: if it feels dry, it's time to water; if it's still damp, wait a few days and check again. As a rough guide, many common plants need water every 1 to 2 weeks, but this changes with light, pot size, and the season (they drink more in summer, less in winter). When in doubt, it's safer to wait—most houseplants bounce back from being a little thirsty far more easily than from soggy, overwatered soil.
Do I need a pot with drainage holes?
Yes—drainage holes are the single easiest way to avoid killing a plant. They let extra water escape so the roots aren't sitting in soggy soil, which is the most common cause of root rot. They're also required for bottom watering to work. If you fall in love with a cute pot that has no holes, use it as a 'cover pot': keep the plant in a plastic nursery pot with holes and just set that inside the decorative one. Water in the sink, let it drain, then pop it back. If you ever see standing water in the bottom of a cover pot, tip it out.
