To prevent and treat common pests on houseplants, regularly inspect leaves and stems for signs of infestation. Keep plants healthy, as stressed plants attract pests. For prevention, use neem oil or insecticidal soap sprays. If pests are present, isolate the affected plant, remove visible pests by hand or with a water spray, and treat with appropriate insecticides or natural remedies like diluted soap water. Regularly clean plant leaves to remove dust and debris, which can harbor pests.

To repot an indoor plant, first choose a new pot that is slightly larger than the current one. Gently remove the plant, shaking off excess soil and untangling roots. Place some fresh potting mix in the new pot, position the plant in the center, and fill around it with more soil. Water thoroughly to settle the plant and eliminate air pockets.
