You will need a few basic items to create a container garden from a found object. These are what I used for this project.
A cordless drill
Left over latex paint
Depending on what your object is you may decide to use a cheap plastic pot as an insert.
Second because I wanted to pretty it up I painted the box with latex paint and lined it with weed cloth. The holes where small but I prefer to keep as much of my potting mix in my container and not running all over the table top where this will live. A bit more decorating with some acrylic paint to add lettering and my container was ready for soil.
I will post pictures in a few weeks to show how this has grown....but for me this is the perfect kind of project...most of the plants were started from seed and cost us pennies. Many were volunteers in the garden, so we can say that this project cost us under $10 after buying the potting soil! Not bad for a pretty little garden.
