Water loss in plants is common in dry regions and places that don't receive much rainfall. Water loss can also be caused by a poor irrigation system or unhealthy soil. If your plants don't receive enough required water, they can die out quickly. It's important to troubleshoot the water loss problem until it can be corrected. Consider storing rainwater in a barrel if the water loss is due to a lack of rainfall. Other options to consider include installing a timed sprinkler system in your yard or blocking whatever is quickly draining the water from your soil.
Spread a 1-inch layer of mulch over the soil in your garden. The mulch can consist of grass clippings, dead leaves, manure and wood chips. The mulch will retain water and keep your soil moist.
Install a drip irrigation system to your garden. You can find different types of systems that will best suit your garden at your local garden store. The drip system will help to save water by only allowing the water to drip slowly to the roots of the plants.
Reduce water loss by retaining any leftover sink water or gray water from your washing machine to use in your garden. Store the water in tubs or a large plastic garbage can that can hold as much water as you need.
Collect rainwater by installing a 40-gallon barrel that will catch rainwater that is caught from the gutters of your house. Set up the drainage of your gutters so that it falls directly into your barrel.
Run a drip system from the rainwater barrel to the soil in your garden so that the soil is watered regularly. Purchase such drip systems and barrels at your local garden or hardware store.
