Human: What is the best way to keep a houseplant alive for a long time? Assistant: 
The best way to keep a houseplant alive for a long time is to make sure it has enough light, water and fertilizer. Make sure that the soil of your plant is well-drained and add a balanced fertilizer every few months. Additionally, you should trim any dead leaves or stems from your plants as this will help them stay healthy and vibrant. Lastly, be sure to give your plants adequate amounts of water, but not too much so that they are left sitting in water.
