This updated guide covers the essentials of houseplant care: how to check soil moisture and water correctly, feeding strategies, protecting plants from temperature swings, effective ways to raise humidity, when and how to repot, and matching plants to light conditions. It includes practical alternatives to misting and quick plant placement suggestions.

Why houseplants need basic care

Houseplants brighten a room, improve air quality, and can lift your mood. They are living organisms and need consistent care. Ignore watering, light, nutrients, temperature and humidity, and they will show stress.

Watering: not too much, not too little

Check soil moisture by pushing your fingertip into the pot to the first knuckle. If the soil is damp at that depth, wait to water. If it feels dry, water thoroughly until excess runs from the drainage hole and let the pot drain. Use room-temperature water to avoid shocking the roots.

Most common houseplants tolerate tap water. Plants that prefer low-mineral or acidic water - examples include many orchids, gardenias, azaleas, and some carnivorous plants - often do better with rainwater, distilled, or filtered water.

Feeding: replace what the potting mix uses up

Houseplants get nutrients from potting mix and from fertilizer. Use a balanced liquid feed during the active growing season (spring-summer) or a slow-release fertilizer if you prefer fewer applications. Use a higher-nitrogen formula for leafy plants and a higher-potassium (potash) formula for flowering plants. Watch for slowed growth or yellowing leaves; those can indicate a need for feeding.

Temperature and placement

Follow the temperature range on plant tags when available. Avoid placing plants in spots with repeated rapid temperature swings - near unshielded radiators, heat vents, or frequently opened exterior doors. Most houseplants do best in stable indoor temperatures and away from cold drafts.

Humidity: options that work

Central heating lowers indoor humidity. Many tropical plants (thin or broad leaves) benefit from higher humidity. Effective options:
  • Place pots on a tray of damp pebbles so evaporation raises local humidity.
  • Group plants together to create a microclimate.
  • Use a room humidifier for consistent humidity.
Misting can help briefly but does not reliably raise humidity and may encourage pests or fungal problems if leaves stay wet.

Pot size and repotting

Plants will show signs they need repotting: slowed growth and faster drying of the potting mix. Repot into a container one size larger, using a fresh, appropriate potting mix (for example, orchid bark for orchids, a well-draining mix for succulents). Ensure good drainage.

Matching plant to place

Choose the right plant for the light available. Shade-loving ferns will decline in bright, direct sun; flowering houseplants typically need brighter light. Light intensity falls rapidly with distance from a window, so move plants closer to the window if they need more light.

Quick plant suggestions

  • Sunny windowsill: Hibiscus
  • Occasional sun: African violet
  • Bright, indirect light: Monstera (Swiss cheese plant)
  • Semi-shade: Spider plant
  • Low light: Aspidistra

FAQs about Houseplants

How often should I water my houseplants?
Water when the top soil at your fingertip (first knuckle) feels dry. Frequency depends on plant type, pot size, and season - most need more water in spring and summer and less in winter.
Can I mist my plants to increase humidity?
Misting gives short-term leaf wetting but rarely raises ambient humidity. Use a pebble tray, group plants, or a room humidifier for sustained humidity; avoid keeping leaves wet for long to reduce pest and fungal risk.
What fertilizer should I use?
Use a balanced liquid fertilizer during the growing season or a slow-release option for less frequent feeding. Choose a higher-nitrogen feed for foliage plants and higher-potassium for flowering varieties.
When should I repot a plant?
Repot when growth slows, roots appear through drainage holes, or soil dries out very quickly. Move up one pot size and refresh the potting mix appropriate to the plant type.
Which plants tolerate low light?
Low-light-tolerant options include Aspidistra and some species of fern and snake plant, but flowering plants generally need brighter light.
