Growing Trees in Earthboxes

EarthBox planters, and other self-watering containers, give you the option to grow a wide variety of plants in small spaces. Using self-watering planters allows you to grow trees on patios, decks, porches and balconies, in small yards or with poor soil. Growing in self-watering containers also minimizes your time maintaining the plants. Developed by Blake Whisenant, the EarthBox takes up little space at 29 inches long and 13.5 inches deep. The height of 11 inches and the design intended for growing vegetables means you can only grow small species of trees in the container.

Instructions

    • 1

      Choose columnar and dwarf varieties of trees for container growing. Some trees for container gardening include columnar apples, dwarf peaches and cherries, Norfolk Island pine, papaya, dwarf bananas, star magnolia and citrus trees.

    • 2

      Make or purchase premade potting soil. A soilless mix works well in large containers to reduce the weight. An EarthBox filled with soil and water weighs approximately 80 lb. You need about 2 cubic feet of growing medium per container.

    • 3

      Place the EarthBox where you want it. Consider the trees' lighting needs. The location should have wind protection and the proper amount of sun.

    • 4

      Wet the potting mix thoroughly. Add the wet mix into the container. This will prevent later settling of the mix.

    • 5

      Plant the tree in the EarthBox. Pull the soil away from the center and place the tree in up to its crown. Replace the soil mix, but do not cover the crown. Install a plastic mulch cover or an organic mulch to conserve moisture and prevent windblown weed seeds from taking root.

    • 6

      Fill the water reservoir. During hot or dry weather, you need to check the water reservoir daily and fill it full. EarthBox planters have a water reservoir that holds 2.2 gallons of water.

      Add fertilizer as needed. Follow the manufacturer's directions and any guidelines for the species of tree you planted.
