• Watering: Water regularly to keep the soil moist.
• Harvest: Radishes are ready to harvest in as little as 25-30 days.

6. Lettuce

Lettuce is a cool-season crop that does well in bags, giving you a continuous harvest of fresh greens.

Growing Tips:

Practical Tips for Growing Vegetables in Bags

For successful container gardening, it's essential to choose the right container and potting mix. Here are some tips:

• Container size: Make sure the bag is large enough for the vegetable’s root system. Larger bags are better for root vegetables like potatoes, while smaller ones work for lettuce or radishes.
• Potting mix: Use a high-quality, well-draining potting mix rich in organic matter. Avoid garden soil, which can compact in containers.
• Fertilization: Feed your vegetables regularly with a balanced fertilizer. Slow-release organic fertilizers work well for long-growing crops like tomatoes and eggplants.

Common Mistakes and How to Avoid Them

• Overwatering: Watering too much can lead to root rot. Always check the soil moisture before watering.
• Poor drainage: Ensure your bags have adequate drainage holes to prevent waterlogging.
• Wrong container size: Using bags that are too small for certain plants can stunt growth. Always choose the appropriate size for each vegetable.

Conclusion

Bag gardening is a simple and effective way to grow your own vegetables, even with limited space. Whether you want to enjoy fresh tomatoes, crispy lettuce, or homegrown potatoes, all you need is a few bags, some soil, and a little bit of know-how. Start small and experiment with different vegetables, and before you know it, you’ll have a thriving urban garden.
