DIY herb gardens. Cut the soda bottle or any plastic bottle with a cover. Turn upside down; attach to board. I'm thinking of leaving the cover to the bottle on; punch in a few holes to drain excess water, but not have the soil drain out with it
Technically I did this last year and reprised it this year. My little container herb garden is thriving this year although I lost my original basil to some mystery issue. I have chives (which are flowering and pretty!), sweet basil, chocolate mint, spearmint, rosemary, sage, thyme.
