Creating a mini gum garden in an outdoor plant box is a delightful way to enjoy the beauty of gum trees in a compact space. Here’s a step-by-step guide to help you get started:

1. Choose the Right Plant Box: Select a sturdy, well-draining outdoor plant box large enough to accommodate the root system of your gum tree seedlings. Opt for materials like cedar or recycled plastic for durability.

2. Select Gum Tree Varieties: Pick smaller gum tree species, such as dwarf eucalyptus or lemon-scented gum, which thrive in confined spaces. Ensure they are suitable for your climate.

3. Prepare the Soil: Use a mix of potting soil and sand to ensure good drainage. Gum trees prefer slightly acidic to neutral soil, so test the pH and adjust if necessary.

4. Plant the Seedlings: Space the seedlings evenly to allow room for growth. Water them thoroughly after planting and place the box in a sunny spot, as gum trees love sunlight.

5. Maintain Your Garden: Water regularly but avoid overwatering. Prune the trees occasionally to maintain their shape and remove dead leaves. Fertilize lightly during the growing season.

With these simple steps, your mini gum garden will flourish, adding a touch of nature to your outdoor space. Happy gardening!
