What Do Plants Need to Live?

Plants require water and nutrients to live. Most plants also require light, temperature, space, time, healthy soil and clean air. Plants perform chemical and physical processes similar to other living organisms that allow them to sustain life.

Plants use a process called photosynthesis to create their own food. This process requires sunlight and a cell pigment called chlorophyll, which gives plants their green hue. A lack of adequate sunlight often causes plants to produce less fruits or flowers, and it can weaken the plant. Poor air quality can also prevent photosynthesis, as plants need to be able to take in carbon dioxide from the air to complete the photosynthesis process.

Plants require healthy soil in order to receive nutrients that are necessary for survival. The soil also keeps the plant firmly grounded. Providing fertilizer helps to keep plants healthy by providing additional nutrients not found in the soil. Nitrogen, phosphorous and potassium are the most essential nutrients required by the majority of plants.

Plants are affected by temperatures, and many plants die if subjected to extreme cold or hot temperatures. Plants require ample space to grow and live. If they are confined, plants are often subject to diseases due to a lack of proper airflow.
