What a great idea. Going on vacation? Who will water your container gardens while you are away? I tried this last year for a client, with great success. What I did:

1) create a hole in the container garden about 3” deep with the empty neck of the wine bottle;

2) fill the wine bottle with water (if you want to add decorative stones in the bottle to filter the water, do so first);

3) hold fingers over the opening of the bottle and quickly tip it upside down (straight up or at a slight angle) into the hole you’ve already made in the container; and

4) quickly nestle the bottle into the soil, tapping soil around the neck opening to make sure it is stable and upright.

Smaller containers: try a beer bottle or other decorative glass bottle!
