Creating a mini nocino garden in an outdoor plant box is a delightful way to grow your own walnuts for homemade walnut liqueur, even in small urban spaces. Here’s a step-by-step guide to help you get started.

1. Choose the Right Plant Box: Select a sturdy outdoor plant box with good drainage. A size of at least 24 inches deep and wide is ideal for walnut saplings.

2. Select Walnut Saplings: Opt for young walnut trees, such as Juglans regia, which are well-suited for container growth. Ensure they are healthy and disease-free.

3. Prepare the Soil: Use well-draining, nutrient-rich soil mixed with compost. Walnuts thrive in slightly acidic to neutral pH levels (6.0–7.5).

4. Planting: Place the sapling in the center of the box, ensuring the roots are spread evenly. Cover with soil and water thoroughly.

5. Sunlight and Watering: Position the plant box in a sunny spot (6–8 hours of sunlight daily). Water regularly, keeping the soil moist but not waterlogged.

6. Pruning and Care: Trim the tree to maintain a manageable size for the box. Fertilize annually with organic compost to promote growth.

7. Harvesting: After 3–5 years, your walnut tree will produce nuts. Harvest green walnuts in early summer for nocino liqueur.

With patience and care, your mini nocino garden will yield fresh walnuts for delicious homemade liqueur, bringing a touch of rustic charm to your urban space. Happy gardening!
