Growing bulb vegetables in outdoor plant boxes is a fantastic way to maximize space and enjoy fresh, homegrown produce. Whether you're a beginner or an experienced gardener, selecting the right plants is key to a successful harvest. Here are some of the best bulb vegetables to grow in outdoor plant boxes:

1. Onions – Easy to grow and versatile, onions thrive in containers. Choose short-day varieties for warmer climates and long-day varieties for cooler regions.

2. Garlic – Plant garlic cloves in fall for a summer harvest. Hardneck varieties are ideal for colder climates, while softneck types do well in milder areas.

3. Shallots – These mild-flavored bulbs are perfect for small spaces and add a gourmet touch to dishes.

4. Leeks – With their mild onion-like flavor, leeks grow well in deep plant boxes and can be harvested throughout the season.

5. Spring Onions (Scallions) – Fast-growing and compact, spring onions are great for continuous harvesting.

Tips for Success:

- Use well-draining soil to prevent rot.

- Ensure your plant boxes receive at least 6 hours of sunlight daily.

- Water consistently but avoid overwatering.

- Fertilize lightly with a balanced organic fertilizer.

By choosing the right bulb vegetables and following these tips, you can enjoy a bountiful harvest from your outdoor plant boxes. Happy gardening!
