If you're looking for a creative and budget-friendly way to start seeds for your outdoor plant boxes, ice cube trays might just be the perfect solution. These small, compartmentalized containers can serve as excellent seed starters, especially for small plants or herbs. Here’s why and how you can use them effectively.

Why Ice Cube Trays Work

Ice cube trays are designed to hold small amounts of liquid, making them ideal for starting seeds. Their compact size allows you to grow multiple seedlings in a small space, and the individual compartments prevent root entanglement. Plus, they’re easy to find and often reusable, making them an eco-friendly choice.

How to Use Them

1. Clean the Trays: Ensure the trays are free of any residue to avoid mold or bacteria growth.

2. Add Soil: Fill each compartment with a lightweight seed-starting mix.

3. Plant Seeds: Place 1-2 seeds per compartment and cover lightly with soil.

4. Water Gently: Use a spray bottle to moisten the soil without displacing the seeds.

5. Cover and Wait: Place the tray in a warm, sunny spot or under a grow light. Cover with plastic wrap to retain moisture until seeds sprout.

Transplanting to Outdoor Boxes

Once seedlings develop true leaves, carefully pop them out of the trays and transplant them into your outdoor plant boxes. The small root balls minimize transplant shock, giving your plants a healthy start.

Pros and Cons

- *Pros*: Cost-effective, space-saving, and great for small seeds.

- *Cons*: Limited depth for deep-rooted plants, may require careful handling during transplant.

In summary, ice cube trays are a clever hack for seed starting, especially for beginners or those with limited space. Give it a try and watch your garden thrive!
