Caring Tips

Choosing the Right Vegetables

As you see, there are leafy greens to choose from like spinach, lettuce, and Asian greens; root crops like radishes, baby carrots, and beets; and other summer vegetables like bush beans, zucchini, and cucumbers.

Reading Seed Packets

Seed packets contain all the information on planting depth, spacing, and time to maturity. By following these guidelines closely, you'll secure a successful harvest.

Preparing the Raised Beds

Raised beds offer better drainage, controlled soil quality and temperatures, and effective weed management. Vego Garden provides a large collection of raised beds in various sizes to fit any type of backyard or garden, and they even offer planters for indoor gardens, perfect for those with limited backyard space.

Preparing the Soil 

Use a healthy soil mix for your raised beds and ensure the soil temperature stays between 60-75°F for summer crops.

Add Mulching

Use mulch around your plants to keep the soil cool and moist, reduce water evaporation, and suppress weed growth.

Don’t Stop Watering

Water early in the morning or late at night, but not during the afternoon heat, and don’t skip a watering day.

Feed with Fertilizer

Before planting your seeds, use a nutrient-rich and balanced slow-release fertilizer to promote healthy growth and ensure your plants are well-fed and growing quickly.

Final Thoughts

Planting in early summer and harvesting in late summer is a fun way to keep enjoying fresh veggies all season long. It's not just about the food though—it's a chance for kids to learn about how plants grow and to have fun projects together outside. 

Getting your hands dirty in the garden can teach them about soil, water, and the sun's role in making things grow. Plus, it's a great excuse to spend some quality time together as a family, away from screens!
