5. Use Mulch around Plants to Cut down on Evaporation

Adding a generous layer of mulch around your plants creates a protective barrier between the sun’s harsh rays and the moisture-rich soil below. You can easily purchase organic mulch at a local nursery or craft your own at home using recycled materials:

Layer the mulch so it is at least 3 to 4 inches deep around plant bases. When combined with deep watering tools like a soaker hose, mulching dramatically slows down soil evaporation and keeps your plant roots cool during hot summer days.

4. Check the Moisture Level of the Soil before Watering

Many home gardeners fall into the trap of watering on a rigid daily schedule regardless of whether the soil actually needs it. Before reaching for the hose, simple soil inspection or the classic finger test can prevent overwatering. Insert your finger about two inches into the soil in various garden beds to check the moisture level before turning on the tap. For precise scientific guidelines on soil moisture monitoring, consult resources from the U.S. Geological Survey. If the soil feels damp below the surface, skip watering for the day and let the roots breathe.

3. Water Plants as Close to the Root System as Possible

Avoid using a sprayer that mists foliage, as fine water droplets evaporate into the warm air before reaching the ground. Leaves do not absorb water for hydration, so directing moisture toward foliage wastes significant amounts of water. The roots are where a plant requires the most water. Position your hose or sprayer so you are watering the ground directly at the root zone rather than the air. You can also pair this practice with mulching around plants to maximize retention right where your garden needs it most.

2. Use a Soaker Hose

Utilizing a soaker hose is an excellent way to make sure the roots get first dibs on water. The flow of water is extremely slow out of these porous hoses, allowing moisture to gently soak deep into the ground instead of running off in a different direction where it goes to waste. According to water efficiency guidelines from EPA WaterSense, drip irrigation and soaker hoses reduce garden water waste significantly compared to traditional sprinklers. Connecting your hose system to a dedicated rain barrel water supply makes your irrigation routine even more sustainable.

1. Catch Water in a Rain Barrel to Use for Plants

If you don’t have to pay for the water you use, then that’s an additional bonus for any home gardener. Position gutters along the house and garage to funnel rainfall into a storage barrel for later use. The more rainwater you catch during storms, the more free water you will have available during dry spells.
