How to care for houseplants, in five rules: match the plant to your light, use a pot with drainage, water only when the soil is ready, feed lightly in the growing season, and look at your plants regularly. Almost every problem beginners run into breaks one of those rules. This guide explains each one, gives a simple weekly routine, and links to the Plantbaes tools for the parts that need numbers.

Rule 1: Light comes first

Light is a plant's food supply. You can get everything else right, but a plant in the wrong light will still struggle. Before buying a plant, look at the spot you have in mind:

Spot Light level Good starter plants
Next to a south- or west-facing window Bright, some direct sun Aloe, ponytail palm, succulents
Near an east window or a metre back from a bright one Bright indirect / medium Monstera, rubber plant, spider plant
North-facing window or a few metres back Low Pothos, snake plant, ZZ, cast iron plant
No window Too dark Only with a grow light

(Directions are for the northern hemisphere. Swap north and south if you live in the southern hemisphere.)

Measure with a phone light meter and convert it with the light meter converter. Then pick a suitable plant with the low-light plant finder, which also covers medium and bright light. Our guide to best low-light houseplants goes deeper on dim rooms.

Rule 2: Pots need drainage

Roots need air as well as water. In a pot with no drainage hole, excess water collects at the bottom, roots suffocate and rot sets in. If you love a decorative pot without a hole, use it as an outer cover with a plastic nursery pot inside, and lift the inner pot out to water.

Pot size matters too. A pot that's much too big holds wet soil the roots can't reach. When repotting, go up only 2 to 5 cm in diameter. The repotting pot size calculator suggests the next size.

Rule 3: Water when the soil is ready, not on a schedule

Overwatering is one of the most common ways beginners lose plants. The fix is a habit: check the soil before every watering.

  1. Push a finger a few centimetres into the soil, or lift the pot to feel its weight.
  2. If it has reached the dryness the plant likes, water thoroughly until water drains out.
  3. Empty the saucer after 10 to 15 minutes.
  4. If the soil isn't ready, wait and check again in a few days.
Plant prefers Water when
Drying out (succulents, snake plant, ZZ) Soil is dry all the way down
Dry top (monstera, pothos, most foliage plants) Top 2–5 cm are dry
Moist (ferns, prayer plant, peace lily) Surface just starting to dry

The watering schedule builder gives you a check interval for each plant based on light, pot and season. The full technique is in how to water houseplants.

Rule 4: The right soil

Most houseplants do well in a good-quality potting mix with some extra perlite for drainage. Some groups prefer something different:

Plant group Mix
Most foliage plants General: 70% potting soil, 30% perlite
Monstera, philodendron, pothos (aroids) Chunky: soil, orchid bark, perlite
Succulents and cacti Gritty: cactus soil with lots of pumice or perlite
Ferns, calatheas Moisture-holding: soil with coco coir

Garden soil is usually too dense for pots and may bring pests. Use bagged potting mix. The soil mix calculator turns these recipes into litres.

Rule 5: Feed lightly in the growing season

Potting mix runs low on nutrients over time. During spring and summer, feed with a liquid houseplant fertilizer as the label directs. Many growers prefer half strength or weaker. Stop or reduce feeding in autumn and winter, and skip it for a month after repotting. The fertilizer dilution calculator works out exact millilitres.

More fertilizer doesn't mean more growth. Excess fertilizer salts build up and can burn roots, causing brown leaf tips and white crust on the soil.

Humidity and temperature

Most common houseplants are happy in normal room conditions. A few things help:

  • Keep plants away from radiators, heaters and air-con vents, which dry the air and soil quickly.
  • Avoid cold drafts from doors and single-glazed windows in winter.
  • Humidity lovers such as ferns and prayer plants do well in a bright bathroom or grouped with other plants. A tray of wet pebbles under the pot (with the pot sitting above the water) is a common approach.

Reading your plant

Leaves tell you a lot. Learn the common signals:

What you see Likely cause
Yellow lower leaves, wet soil Overwatering
Drooping, dry soil Thirsty
Brown crispy tips Dry air, irregular watering, or salt build-up
Leggy stems, small new leaves Not enough light
Pale, bleached patches Too much direct sun
Sticky leaves, webbing, white fluff Pests (aphids, spider mites, mealybugs)
One old leaf yellowing occasionally Normal ageing

Pests: catch them early

Check under leaves and along stems every week or two. Common pests include spider mites (fine webbing, speckled leaves), mealybugs (white cottony clusters), scale (small brown bumps), fungus gnats (tiny flies around wet soil) and thrips.

If you find pests:

  1. Isolate the plant so they don't spread.
  2. Wipe or rinse the leaves. A shower spray removes many pests.
  3. Let the soil dry more between waterings if you see fungus gnats.
  4. Use a houseplant treatment if needed, following its label exactly.

A simple weekly routine

Day Task Time
Once a week Walk round your plants, check soil, water those that are ready 10–15 min
Once a week Look under a few leaves for pests 2 min
Every 2–4 weeks Rotate pots a quarter-turn; wipe dusty leaves 5 min
Spring–summer, every few weeks Feed at the label's dilution 5 min
Spring, yearly Check if any plant needs repotting varies

Bringing a new plant home

The first few weeks set the tone. Some practical steps:

  1. Inspect before you buy. Look under leaves and at the soil surface for pests, and avoid plants with mushy stems or a sour smell.
  2. Quarantine for two weeks. Keep a new plant away from your others until you're sure it isn't carrying pests.
  3. Expect a little sulking. Moving from a bright greenhouse to a home is a big change. A yellow leaf or two in the first weeks is common.
  4. Don't repot straight away unless roots are bursting out or the soil is waterlogged. Let it settle first.
  5. Check the nursery soil. Some plants come in very dense, peaty soil that stays wet for a long time. Check it carefully before the first watering at home.

Seasonal care at a glance

Season What changes
Spring Growth restarts. Repot root-bound plants, begin feeding, check soil more often.
Summer Peak growth and water use. Watch for sun scorch and spider mites.
Autumn Light drops. Move plants closer to windows, taper feeding.
Winter Slow growth. Water much less, keep away from radiators and cold glass.

Pets and children

Many popular houseplants, including pothos, monstera, philodendron, snake plant, peace lily and aloe, are listed by the ASPCA as toxic to cats and dogs. If you have pets that chew plants, choose non-toxic species or keep plants out of reach. The low-light plant finder has a pet-safe filter. If a pet or child may have eaten a plant, contact your vet, poison control or a doctor straight away.

Your first plant: a checklist

  • Measured the light where it will live
  • Chosen a plant that suits that light
  • Pot with a drainage hole
  • Bagged potting mix (with perlite if needed)
  • Watering schedule set up as soil-check reminders
  • Checked pet toxicity if you have animals
  • Left it in its nursery pot for a couple of weeks before repotting, unless it's badly root-bound

Where to go next

For plant-specific care, see the monstera care guide and the pothos care guide. Print a care card for each plant if someone else will look after them while you're away.

Frequently asked questions

What is the easiest houseplant for beginners?

Golden pothos, snake plant and ZZ plant are widely considered among the most forgiving. They tolerate a range of light and occasional missed waterings.

How do I keep my houseplants alive?

Match each plant to the light you have, use pots with drainage, water only when the soil is ready, and watch for changes in the leaves. Most beginner losses come from overwatering and too little light.

How often should I fertilize houseplants?

Most products suggest feeding during spring and summer and reducing or stopping in autumn and winter. Follow the label and consider using a weaker dilution for slow growers.

Why do my houseplants keep dying?

The most common reasons are overwatering, a pot without drainage, not enough light, and sudden changes such as moving the plant next to a radiator or a cold window.
