Plants do not need soil to grow. For years, gardeners have used a technique called hydroponics to cultivate and grow plants in a water solution. By transferring a plant from a small pot to a container full of water, you eliminate the need to water it. This also allows you to monitor your plant more efficiently and prevent soil-related plant diseases. To begin hydroponic gardening, all you need are a few materials.
Select a container for the plant. Any container will work as long as the plant fits the container. Choosing a transparent container such as glass will allow you to view the plant and its roots as it grows. Clean the container with hot water and soap.
Place a layer of small pebbles, gravel, or other objects in the bottom of the container. These will support the plant during its initial growth stages in the water. After the plant begins to grow, it will gain more support on its own as its roots fill the container. Cheap gravel found in pet stores makes an inexpensive support system. If you have glass marbles, they will work as well.
Remove your plant from its existing pot or vase. If the soil around the roots is moist, allow it to dry before proceeding. Dry soil will simplify the task of removing it from the roots before transferring the plant to the new container.
Gently rub the plant's roots to remove the soil. Do not bruise the roots by rubbing too hard.
Hold the roots under a stream of running water to remove all traces of dirt.
Place the plant into the container, and spread its roots across the bottom. Add additional pebbles, gravel, or other support objects to the container until the plant stands on its own.
Add spring water or well water to the container. Add enough water to cover the plant's roots and part of the stem. Do not overfill the container so that the water touches the leaves.
Wait seven days, and pour the water out of the container.
Fill a gallon bucket with water. Add soluble powdered plant food to the water. Use half the recommended amount of powder. It's better to underfeed the plant than overfeed it.
Mix the solution well. Pour enough solution into the container to cover the plant's roots and part of the stem.
