Mini Water Gardens
Gardening by the Yard : Episode GBY-710 -- More Projects »
When you think of container gardening, you probably think of growing plants in pots with soil. But why not make a splash by using water instead? Mini water gardens offer the opportunity to grow a variety of unusual plants, and since the little water features don't require plumbing or electricity, the floating displays are surprisingly easy to do.
To get your mini-water garden started, purchase a non-porous, glazed container (preferably one without drainage holes) (figure A), a few water plants and water. If your pot already has holes in the bottom, use silicon caulk to plug them. Choose water plants--such as a standard umbrella plant, dwarf umbrella plant, and curly sedge--that are proportionate to the size of the container. Fill the pot ¾ full of water. Let the container sit for several hours or, ideally, overnight so any harmful gases have time to evaporate. Place a few small stones along the bottom of the container and position the plants in the pot, positioning the tallest plant in the back and leaving the plants in their individual plastic containers. Set a larger rock on each separate plant container to secure it in place.
"Maintenance-wise, taking care of one of these couldn't be easier," says master gardener Paul James. "Add fresh water to top off the container as the level drops due to evaporation. And since an open container of water is a breeding ground for mosquito larvae, add a little granulated Bt to prevent pests from multiplying (figure B). Place your mini-water garden in a location with plenty of morning sun. Avoid places that might receive late afternoon sun because the harsh rays can burn your plants and heat the water.
