There are a variety of ways to grow a vertical garden. You might grow a vertical garden to decorate a wall with a tapestry of living color and texture or you might grow a vertical garden when horizontal ground space is limited. The type of vertical garden described here is intended for intrepid gardeners who have access to a fire escape or small patio and want the irreplaceable taste of fresh homegrown vegetables.
Determine how much room you have for your vertical garden and which plants you want to grow. Excellent candidates for vertical gardening using a trellis are tomatoes, cucumbers, squash and pole beans. Choose as many as your budget and space will allow.
Add potting soil until the pot is full to within three to four inches of the top. Carefully remove the plant from its liner, taking care to not disturb the roots. Create an indention in the soil and gently place the plant in the soil. Gently water the soil in the container and let it settle. Add more potting soil gently around the plant's root ball and water again. Do this two or three times until you have the soil nicely settled in the container with none of the root ball showing.
