Houseplant Care for Beginners: A First-Year Roadmap

The short answer: most beginner houseplant problems come from two mistakes. One is putting a plant in the wrong light. The other is watering on a schedule instead of when the pot needs it. Pick a plant that suits the spot you already have, check the potting mix before every watering, feed only while the plant is growing, and look it over once a week. University of Maryland Extension calls light "probably the most essential factor for healthy indoor plant growth" (Lighting for Indoor Plants). Utah State University Extension says overwatering "is likely the number one killer of house plants" (Help for Houseplants).

Before you buy: match the plant to the spot

Read your light first

Look at the spot before you look at plants. The RHS points out that no plant will tolerate complete darkness, such as a windowless room, because plants need daylight to make their own food (RHS: Easy care houseplants). Window direction gives a first clue. University of Maryland Extension pairs north-facing windows with low-light plants, east- and west-facing windows with medium-bright light, and south-facing windows with high light. That pairing comes from a US source and assumes a Northern Hemisphere home. Distance matters as much as direction, because light intensity drops quickly as a plant moves away from the window (UMD Extension).

Don't trust your eyes on this. Your pupils adjust to dim rooms, so a dark room seems brighter than it is, which makes it "nearly impossible" to judge how much light a plant gets by eye (Virginia Tech, SPES-720). If a label asks for bright, indirect light, the RHS description of "bright shade" is a useful test: bright light that does not cast a sharply defined shadow (RHS: How to grow houseplants). For individual plants, see how much light pothos need, Monstera light requirements, orchid light needs and whether cacti need direct sun.

Pets and toxicity

If you live with cats or dogs, check a plant before you buy it. The ASPCA's Toxic and Non-Toxic Plants database lets you search by common or scientific name, and you can filter it to show plants toxic or non-toxic to dogs, cats or horses. Look up the exact name on the plant label. Keep two ASPCA cautions in mind. The list "is not meant to be all-inclusive", and eating any plant material may cause vomiting and stomach upset in dogs and cats. The ASPCA's 24-hour poison control line is (888) 426-4435. For plants you may already own, see are pothos toxic to dogs, are Monsteras toxic to cats and are orchids poisonous.

What to check at the shop

Shape: look for a balanced plant with no dieback (RHS). A good one should not look leggy or sparse (Illinois Extension: Get Started).
Leaves and stems: inspect the leaves carefully, and look closely at stems and leaves for insects or disease (Illinois Extension). Turn a few leaves over, because the RHS notes that scale insects sit on stems and leaf undersides.
Moisture: avoid plants wilting in dry compost, and especially plants wilting while their compost is moist or wet (RHS).
Roots: roots growing through the drainage holes or showing at the soil surface mean the plant has probably outgrown its pot (Illinois Extension).

Your first month

Settling in: expect some leaf drop

Plants often drop or yellow a few leaves when they first arrive somewhere new. Illinois Extension says this adjustment period should not last more than a few weeks. It also suggests keeping a new plant away from your other plants for two to three weeks, keeping it relatively cool to reduce water loss through the leaves, and not fertilizing while it adjusts (Illinois Extension: Get Started).

Pot and drainage: why the hole matters

Containers with drainage holes are best for most plants, and pots without them carry a greater risk of root rot (Illinois Extension). Decorative pots often have no hole. In that case, keep the plant in a plain pot with a hole and set that inside the decorative one, which is called double potting (CSU PlantTalk 1315). Never let a plant sit in water, and empty saucers after watering (UMD Extension: Watering Indoor Plants). More detail: does pothos need drainage holes and do snake plants need drainage holes.

Potting mix basics

Houseplants do best in a sterilized mix that drains well, and garden soil alone will not drain adequately in a pot. As a general mix, Illinois Extension suggests equal parts soil, peat moss and perlite or vermiculite (Illinois Extension). Some groups need something different. Succulents need a sharp-draining mix that dries quickly (Iowa State Extension), and orchids are usually repotted into a bark mix for air and drainage (Clemson Extension). Don't jump to a much bigger pot: a small plant in a large pot stays too wet for too long, so move up one pot size at a time (Illinois Extension). See also the best soil for pothos and whether cactus soil works for other plants.

Watering without a calendar

Plants "should not be watered on a schedule, but rather should be watered when they need it" (UMD Extension). Light, temperature, humidity, pot size and the potting mix all change how fast a pot dries (USU Extension). Check the pot instead of the calendar:

Feel the mix. Push a finger about two inches into the mix. If it is dry at that depth, the plant probably needs water (UMD Extension; Illinois Extension).
Lift the pot. A dry pot is much lighter than a wet one (UMD Extension; RHS).
Water thoroughly. Water until it drains freely from the bottom of the pot (UMD Extension), using room-temperature water rather than cold (Illinois Extension).
Empty the saucer. Pour away the water that collects in the saucer after an hour or so (USU Extension).

A wilting plant doesn't always need water. Wilting is often a sign of thirst, but it can also be a symptom of overwatering (Illinois Extension), so check the mix before you reach for the watering can. For more, see how often to water pothos, how to water Monstera and signs of an overwatered pothos. Our watering assistant walks you through these checks for your plant and pot.

Feeding: only while the plant is growing

Feed during the growing season and ease off in winter. The RHS gives the feeding season as March to October and says winter feeding should be limited to once a month at most. Illinois Extension says to fertilize only while plants are actively growing, and that plants resting through short winter days usually need very little or no fertilizer (RHS; Illinois Extension: Care). The two sources suggest different intervals during the growing season. Whatever product you use, follow the label rate and never go above the recommended strength (Illinois Extension). Two more points:

Don't feed a plant whose soil is dry, because fertilizer applied to dry soil can burn the roots (RHS). Water first.
Fertilizer salts build up over time. Brown leaf tips and a crusty deposit on the soil surface or around the drainage holes are warning signs. Flush the pot with plenty of water before fertilizing (UMD Extension).

Humidity, temperature and draughts

Most foliage plants prefer daytime temperatures of 65–75°F (about 18–24°C), with nights 5 to 10°F (about 3–6°C) cooler (Illinois Extension: Care). Watch for hot and cold spots:

Keep plants away from blasts of hot or cold air from windows and radiators. Leaves touching cold window glass can be damaged (Illinois Extension).
Close to a radiator, leaves can dry out and turn brown at the edges. Cold draughts can shock a plant and make it collapse. In winter, don't leave plants behind drawn curtains, where the space can get very cold (RHS).

Indoor air gets dry in winter. Illinois Extension says most homes are below 30 percent humidity then. It recommends a humidifier, pebble trays with the pots kept out of the water, or grouping plants together (Illinois Extension). The RHS also suggests grouping plants and standing them over trays of moist gravel. Sources disagree about misting. The RHS says spraying can help if done frequently, while Illinois Extension says misting doesn't always work, its effect is brief, and too much of it can increase disease. More: Monstera humidity, pothos humidity and Monstera temperature.

Weekly five-minute check

Once a week, look over each plant for a few minutes:

The mix: do the finger and weight checks, and water only if they show the pot is drying out.
Leaf undersides and stems: the RHS lists the common signs. Fine webbing and straw-coloured speckling point to red spider mite. White, cotton-wool-like blobs are mealybugs. Light brown, limpet-like insects on stems and leaf undersides are scale. Minute black flies are sciarid flies, also called fungus gnats (RHS). Fungus gnats can also be a sign that a plant is being overwatered (USU Extension).
New growth: spindly, "leggy" stems and faded leaves suggest too little light. Pale leaves that turn brown suggest too much direct light (UMD Extension).
The soil surface: a white crust can mean salts are building up (USU Extension). Algae on the compost surface can mean the compost has gone sour (RHS).

Problem guides: bugs on pothos, scale on Monstera, thrips on Monstera, leggy pothos, pothos sunburn and yellow mold in plant soil.

When to repot

Repot when the plant tells you to, not on a date. Signs include roots growing through the drainage holes, a soil mass filled with roots, roots on the soil surface, smaller new leaves, and wilting between waterings (Illinois Extension: Repotting). A plant that dries out very quickly and makes little growth may be pot-bound (RHS).

When: spring or early summer, while the plant is actively growing (Illinois Extension). The RHS suggests potting on every two to three years, because compost breaks down and compacts over time.
How much bigger: keep the step small. The RHS suggests a pot 5–10 cm (2–4 in) wider than the current one. CSU suggests a container one or two inches wider than the root ball (CSU PlantTalk 1315).
How: knock the plant gently out of its pot, check the roots, and replant at the same depth in fresh mix. Press the mix gently around the roots and water straight away (Illinois Extension).

Care rules to drop

"Houseplants will purify the air in your home"

A review of indoor-greening research led by the University of Surrey notes that "many older experiments used unrealistic numbers of plants or controlled chambers in labs". The pollutant reductions it describes come from engineered greening systems, and depend on plant density, lighting and design (University of Surrey). So that evidence doesn't show that a few ordinary pots will clean the air in a room. Grow houseplants because you enjoy them. Read more in Monstera benefits: real and myth and do cacti produce oxygen.

"Add gravel to the bottom of the pot for drainage"

Iowa State Extension says a "drainage layer" of coarse gravel at the bottom of a container is not a suitable replacement for a drainage hole (Iowa State Extension). See why gravel doesn't solve poor drainage.

"Ice cubes are the way to water any orchid"

Ohio State researchers found ice cubes to be "a practical way to water Phalaenopsis orchids grown in bark media" (Ohio State). That finding covers moth orchids in bark, not every orchid or potting medium. The researchers also note that water needs vary between cultivars and that you should watch the plant and give more or less water as it needs. As with any houseplant, let the condition of the potting medium decide when to water, not the calendar. See how to water an orchid.

"Mist daily for humidity"

Misting "does not always work well", its effect is brief, and heavy misting can increase disease (Illinois Extension). Illinois Extension suggests a humidifier, pebble trays or grouping plants instead. See what actually helps Monstera humidity.

"More hours of light are always better"

Most plants need a dark period. UMD Extension advises no more than 16 hours of light a day in total (UMD Extension), and Illinois Extension says plants need a rest period too (Illinois Extension: Lighting). See can you leave grow lights on 24 hours a day.

Frequently asked questions

How do I know when to water a houseplant?

Push a finger about two inches into the potting mix. If it is dry at that depth, the plant probably needs water. You can also lift the pot, because a dry pot is much lighter than a wet one (University of Maryland Extension). Water when the pot needs it, not on a schedule.

Why is my new houseplant dropping leaves?

Plants often drop or yellow a few leaves after moving to a new place. Illinois Extension says this adjustment period should not last more than a few weeks. Keep the plant somewhere suitable, don't fertilize while it settles, and check that the mix isn't staying wet.

Should I fertilize houseplants in winter?

Usually very little or not at all. The RHS limits winter feeding to once a month at most, and Illinois Extension says plants resting through short winter days usually need very little or no fertilizer. Follow the label rate when you do feed.

How often do houseplants need repotting?

Signs are a better guide than dates: roots growing out of the drainage holes, a root-filled soil mass, smaller new leaves, or a pot that dries out very quickly. As a rough guide, the RHS suggests potting on every two to three years, and Illinois Extension recommends repotting in spring or early summer, while the plant is actively growing.

Can a houseplant live in a room with no windows?

Not on daylight alone. The RHS says no plant will tolerate complete darkness, such as a windowless room, because plants need daylight to make their food. University of Maryland Extension lists rooms that are artificially lit alongside north-facing windows as suitable for low-light plants, so a windowless room needs artificial light for any plant to grow there.

Do houseplant pots really need drainage holes?

For most plants, yes. Illinois Extension says containers with drainage holes are best and pots without them carry a greater risk of root rot. To use a decorative pot without a hole, keep the plant in a plain pot with a hole inside it and empty any water that collects.
