Wall of Water 101: Guide to Growing Success

Last Updated: August 24, 2023

The wall of water is a gardening tool that is designed to extend the growing season for plants. It is a plastic sleeve that surrounds the base of a plant and creates a microclimate around it. The tool works by trapping and retaining heat from the sun, which helps to keep the plant warm and protect it from frost and other cold weather conditions.

It typically consists of several interconnected tubes or cells that are filled with water. When the sun shines on the Water Wall, the water inside the tubes absorbs the heat and retains it, creating a warm and humid environment around the plant. This helps to promote faster growth and protect the plant from cold weather damage.

This is a popular tool for gardeners who live in areas with short growing seasons or unpredictable weather. It is also commonly used to protect tender seedlings from frost and other cold weather conditions. With the same, gardeners can extend the growing season and produce more abundant and healthier plants.

Importance of extending the growing season

Extending the growing season is important for several reasons:

  1. Increased Yield: Extending the growing season means more time for plants to mature and produce fruit or vegetables, leading to a larger yield for the same amount of space and effort.
  2. Variety of Crops: With an extended growing season, gardeners have the opportunity to plant a wider variety of crops, including those that require longer growing periods or that might not otherwise thrive in their region.
  3. Cost Savings: By extending the growing season, gardeners can avoid the expense of purchasing produce from grocery stores and farmers’ markets during the off-season.
  4. Gardening as a Hobby: For many gardeners, growing their own food is a hobby that brings them joy and satisfaction. Extending the growing season allows them to spend more time in the garden and enjoy the fruits of their labor for a longer period.
  5. Environmental Benefits: Growing your own food reduces the carbon footprint of transportation and packaging involved in buying products from stores.

How the tool traps and retains heat

These plant protectors traps and retains heat by utilizing the greenhouse effect. When sunlight penetrates the clear plastic tubes or cells of the same, the water inside absorbs the energy from the sun’s rays and heats up.

The water acts as a thermal mass, absorbing and storing the heat. At night or on colder days, the heat from the water radiates back outwards and warms the surrounding air. It also reduces heat loss by blocking wind and shielding the plant from cold temperatures.

By creating a warm and protected environment, the wall of water helps to promote faster growth and protect the plant from frost and other cold weather conditions. This allows gardeners to start planting earlier in the season and to keep their plants growing later into the fall.

Overall, it is a simple but effective tool for creating a microclimate that promotes optimal plant growth and helps to extend the growing season.
