Growing plants in water -- without potting mix -- is easy to do. Here you'll discover how to transfer your plants from soil to water gel crystals or other supporting medium, find out which containers to use, how to supply nutrients to the water, and more.
Some plants can grow directly in water with pebbles for support. Want an easy plant to start out with? Give lucky bamboo a try.
Most plants will get root rot if left in water for long. They'll grow beautifully, however, if placed in clay aggregate or water gel beads. Water beads not only support plants, they absorb water and release it slowly as plants need it.
Just a tip before you get started -- not all plants will grow well in a soilless medium. Take a look at this list of house plants that grow in water.
Soak the crystal gel beads in water for several hours, allowing the beads to absorb as much water as they can. They'll swell up before they're ready to use. Drain off any excess water before potting your plant. House plants grown in gel crystals need watering less often than traditional medium.
Although you can buy plants already growing in water, you can also transfer a house plant from potting mix to hydroculture. Here's how:
This is easy. Add water-soluable fertilizer to water before refilling the container. Growing plants in water are completely dependent on added nutrients, because they are not provided by a potting mix. If your plant looks pale between waterings, apply a foliar (spray) fertilizer up to once a week.
Rainwater is ideal for your house plants. It's naturally soft and free from chlorine, fluoride and other chemicals that plants don't like. Use a rain water barrel to capture it and water your plants.
Hydroculture is a fairly new name for the old method of growing plants in containers filled with water, rather than soil.
Rather than plucking a plant right out of its soil, it's a good idea to take a cutting and root it in water. That way you won't risk tearing any roots.
