Common Mistakes to Avoid

1. Holes Too Large

Reason: Water pours out too quickly, not allowing for gentle watering of seedlings.
Solution: Use a smaller-diameter needle or make multiple smaller holes instead of one large hole.

2. Improper Lid Placement

Reason: The lid is not securely attached, causing leaks and inconsistent watering.
Solution: Ensure the lid is tightly screwed on or use strong adhesive to secure it if necessary.

FAQs

What type of plastic bottle is best for making a DIY watering can?
A sturdy, clear plastic bottle is ideal. Avoid bottles that are thin, easily punctured, or made from a type of plastic that's known to leach chemicals. Look for numbers 1 or 2 inside the recycling symbol on the bottle; these are generally considered safer for this purpose.
