Then I saw an idea for a plant waterer. Lord knows I have plenty of bottles around. For my larger plants, I took some empty glass wine/lemonade bottles, filled them with water, and stuck it mouth down into the dirt. The idea is that the water will pour into the soil as needed. When the soil is saturated, water won't come out. Thus, no need to keep checking if the soil is dry. The plant should basically water itself, and all I need to do is refill the bottle as necessary.
Will this work? Time will tell. As well as dead plants.
