|Some bottles drained fast, others are still full after several hours|
Instead of storing away the bottles though, I've discovered a new use for them. I flipped them upside down and with some pressure, snugged the bottle tops into the soil enough to hold them in (like the wine bottles). I also stuck a stake through each one just to help keep them upright. Each tomato plant got a bottle planted next to it.
Now, instead of watering the whole bed, I simply fill each bottle up with water and let it slowly soak in. That does two things: it provides a steady amount of water over a longer period of time and it prevents the problems that overhead watering causes with tomatoes, i.e. fungal diseases. I know the water is going directly into the root system too. I can add some fertilizer or Epson salts to the bottle when need be. Yet another use for those plastic bottles until they are ready to be recycled or stored.
