The Importance of Watering Your Garden


Watering the garden seems like common sense, but the way we water makes a difference. The importance of water to plant growth is more complex than just a "drink of water" now and then.

Frequency and Amount

To grow and stay healthy, plants must receive water on a regular schedule in an amount suitable to the species. Tomatoes, for example, start blossom end rot with too much or too little water applied irregularly.

The Water Cycle

Plants are a part of the water cycle that provides water for rivers, oceans and aquifers. Plants' consumption and respiration of water is the link between rain and water used for drinking and recreation.


Plants use water to provide hydrogen, which, when combined with carbon dioxide collected from the soil and air, makes carbohydrates and free oxygen. These sugars are the foods upon which plants depend to live and grow.

Trace Elements

Water carries traces of minerals and other nutrients like boron, chloride and iron that complete the daily requirements of plants. Water transports these elements from the soil to the growing cells within plants.

Insulation and Cooling

Water evaporates from plants, cooling them in the summer. Regularly watered plants have well-hydrated cells that help insulate them from fluctuating temperatures and frosty weather.
