Caring for houseplants involves providing the right amount of light, water, and nutrients. Most houseplants thrive in bright, indirect sunlight, but some can tolerate low light. Watering should be done when the top inch of soil feels dry, ensuring not to overwater, which can lead to root rot. Fertilizing houseplants every few months with a balanced fertilizer helps promote healthy growth. It's also important to check for pests like aphids or spider mites and treat them promptly. Regularly dusting leaves can improve photosynthesis and overall plant health.
