7 Simple and Effective Ways to Conserve Water in Home Gardening

by | Jul 14, 2023

Water conservation is a crucial practice in home gardening, not only for environmental sustainability but also to reduce water bills and promote efficient plant growth. According to the Pew Research Center, “Over 2 billion people already lack access to safe drinking water at home, and by 2025 over half of the world’s population will reside in water-stressed areas. These numbers will increase significantly if climate change and population growth follow or exceed predicted trajectories.”

At Trellis for Tomorrow, we prioritize water conservation in all our garden sites, utilizing drip tape irrigation across all sites. In this blog post, we will discuss seven effective ways homeowners can water their gardens wisely by incorporating some water-saving techniques.

Install a Rainwater Collection System

One of the most effective ways to conserve water is by collecting rainwater. Set up a rain barrel or cistern to capture rainwater from your roof’s downspouts. We recommend using a mesh screen to filter debris and prevent mosquito breeding. You can then use this stored rainwater to irrigate your garden during dry spells, reducing reliance on potable water sources. You can find DIY instructions online or purchase ready-to-go rain barrels at a local garden supply center. Check out this locally made version that you can find at Colonial Gardens in Phoenixville or stop into the Eco Store on Bridge Street.

Embrace Drip Tape Irrigation

Drip tape irrigation is a highly efficient method that delivers water directly to the plants’ root zones, minimizing evaporation and runoff. Trellis for Tomorrow utilizes drip tape irrigation in all our garden sites, and homeowners can implement it too. Simply lay the drip tape along your garden rows and connect it to a water source. Drip tape conserves water by providing a slow and steady supply, ensuring plants receive precisely the amount they need. Check out this resource from Rain-Flo Irrigation.

Water Early in the Morning

To minimize water loss through evaporation, it’s best to water your garden early in the morning. By doing so, the water has time to soak into the soil before the sun’s heat intensifies, reducing waste and promoting efficient plant absorption. Watering in the evening can lead to prolonged leaf wetness, increasing the risk of disease.

Utilize Mulch

Mulching around your plants provides several benefits, including water conservation. A layer of mulch helps retain soil moisture, reduces weed growth, and insulates the soil, preventing evaporation. We recommend using organic and undyed mulch such as wood chips, straw, or shredded leaves. Apply a 2–3-inch layer around your plants, leaving a small space near the stem to prevent rot.

Practice Smart Watering

Avoid overwatering your plants by practicing smart watering techniques. Before watering, check the soil moisture by inserting your finger into the soil. If it feels damp an inch below the surface, you can delay watering. Additionally, water deeply and infrequently encourages deeper root growth and drought tolerance. Shallow, frequent watering can lead to shallow roots and plant stress.

Group Plants by Water Needs

Efficiently manage water usage by grouping plants with similar water requirements together. Some plants require less water, while others, like leafy greens, need more. By arranging plants with similar water needs in the same area, you can avoid over or underwatering certain plants, ensuring optimal growth for all.

Capture and Reuse Household Water

In addition to rainwater collection, consider reusing household water to irrigate your garden. Collect water from abandoned cups and activities such as rinsing fruits and vegetables. This water can be used for watering plants or for irrigating with drip tape systems. Ensure the water does not contain harmful chemicals or contaminants.

Conserving water in home gardening is a responsibility we all share. By implementing these seven effective strategies, homeowners can contribute to a sustainable and efficient water management system. Trellis recommends using rainwater collection systems, drip tape irrigation, and other water-saving techniques to protect our environment and promote healthy, thriving gardens. Together we can make water conservation an integral part of gardening practices and pave the way for a greener future.
