Get to know your plants.

Look at how much daylight reaches the leaves and how long direct sun hits them. Bright, indirect light is a well-lit spot out of prolonged, strong sun. Light drops off as you move away from the window. If daylight is limited, try a grow light on a timer. Rotate the pot occasionally if the plant grows toward one side.

Feel below the surface of the mix and lift the pot to see how heavy it feels. When your plant is ready for water, soak the mix and empty the saucer after it drains. Check more or less often as the light, season, and growth change. If a plant wilts while the mix is still wet, check the roots before adding more water.

Use a humidity meter near your plants to see how dry the air gets. Many houseplants adapt to 40–60% humidity, while others prefer more. A humidifier can keep humidity steadier than occasional misting. Leave room for airflow and watch for condensation or leaves that stay wet.

Start with an indoor potting mix. Perlite or pumice can add air space, and orchid bark can give the mix more structure for many aroids. Choose a blend based on how much moisture your plant needs and how quickly the pot dries in your home. Use a container with drainage holes.

Check your plant’s guide for the best method. Many trailing plants need a stem cutting with a node, the point where a leaf joins the stem. Start with a healthy plant and clean tools. Give cuttings bright, indirect light and keep the rooting medium lightly moist, or refresh the water regularly if rooting in water.

Check whether the roots have crowded the pot, the mix has broken down, or drainage has slowed. If the plant needs more room, go up one pot size and choose a pot with drainage holes. Keep the plant at its original depth. Repotting during active growth is usually easier on the plant.

Start by checking when the symptoms appeared and which leaves are affected. Look under the leaves and along the stems for pests. If you suspect pests, separate the plant from the rest of your collection. Check the mix and roots when leaves wilt or yellow. Address one likely cause at a time so you can see what helps.
